Manual:RadioOS FAQ

What is CableFree RadioOS™?

What does CableFree RadioOS™ do?

CableFree RadioOS™ is a router operating system which runs on CableFree Carrier Class Radio devices. It includes fully-featured advanced IP router capabilities.

What features does RadioOS™ have?

RadioOS feature list

Can I use CableFree router to hook up to a service provider via a T1, T3, or other high speed connection?

Yes, you can use CableFree hardware router devices to use the device as your edge router, backbone router, firewall, bandwidth manager, VPN server, wireless access point, HotSpot and much more in one box.

How fast will it be?

CableFree RadioOS depends on the main CPU for routing and traffic processing capability. If many features are used, the CPU power may be the limiting factor for performance. There are various hardware models with different power CPUs to enable higher speed operation

How does RadioOS compare to using a Cisco router?

You can do almost everything that a proprietary router does at a fraction of the cost of such a router and have flexibility in upgrading, ease of management and maintenance.

How secure is the router once it is setup?

Access to the router is protected by username and password. Additional users can be added to the router, specific rights can be set for user groups. Remote access to the router can be restricted by user, IP address. Firewall filtering is the easiest way to protect your router and network.

Logging on and Passwords

What is the username and password when logging on to the router for the first time?

Username is 'admin', and there is no password (hit the 'Enter' key). You can change the password using the '/password' command.

How can I recover a lost password?

If you have forgotten the password, there is no recovery for it. You have to reinstall the router.

After power failure the CableFree router is not starting up again

If you haven't shut the router down, the file system has not been unmounted properly. When starting up, the RadioOS™ will perform a file system check. Depending on the HDD size, it may take several minutes to complete. Do not interrupt the file system check! It would make your installation unusable.

How can I access the router if the LAN interface has been disabled?

Please avoid disabling the LAN interface at all times. If you do, it may prove difficult or impossible to access the devices. Some devices have an internal serial port, which could allow access through the serial console.

Licensing Issues

How many CableFree RadioOS™ installations does one license cover?

The license is per RadioOS installation. Each installed router needs a separate license.

Does the license expire?

The license never expires. The router runs for ever. Your only limitation is to which versions you can upgrade. For example if it says "Upgradable to v4.x", it means you can use all v4 releases, but not v5 This doesn't mean you can't stay on v4.x as long as you want.

What happens if my hardware breaks again, and I lose my replacement key?

The same process is used as above, but this time, we need physical proof that there is in fact been another incident.

How can I enter a new Software Key?

Entering the key from Console/FTP:

• import the attached file with the command '/system license import' (you should upload this file to the router's FTP server)

Entering the key with Console/Telnet:

• use copy/paste to enter the key into a Telnet window (no matter which submenu). Be sure to copy the whole key, including the lines "--BEGIN CABLEFREE SOFTWARE KEY--" and "--END CABLEFREE SOFTWARE KEY--"

Entering the key from Winbox:

• use 'system -> license' menu in Winbox to Paste or Import the key

I have mis-typed the software ID when I purchased the Software Key. How can I fix this?

In the Account Server choose `work with keys`, then select your mis-typed key, and then choose `fix key`.

Upgrading

How can I install additional feature packages?

You have to use the same version package files (extension .npk) as the system package. Use the /system package print command to see the list of installed packages. Check the free space on router's HDD using the /system resource print command before uploading the package files. Make sure you have at least 2MB free disk space on the router after you have uploaded the package files!

Upload the package files using the ftp BINARY mode to the router and issue /system reboot command to shut down the router and reboot. The packages are installed (upgraded) while the router is going for shutdown. You can monitor the installation process on the monitor screen connected to the router. After reboot, the installed packages are listed in the /system package print list.

How can I upgrade?

To upgrade the software, you will need to download the latest package files (*.npk) from our website (the 'system' package plus the ones that you need). Then, connect to the router via FTP and upload the new packages to it by using Binary transfer mode.

Then reboot the router by issuing /system reboot command. More information here: Upgrading_RadioOS

I installed additional feature package, but the relevant interface does not show up under the /interface print list.

You have to obtain (purchase) the required license level or install the NPK package for this interface (for example package 'wireless').

If I do upgrade RadioOS, will I lose my configuration?

No, configuration is kept intact for upgrades within one version family. When upgrading version families (for example, V2.5 to V2.6) you may lose the configuration of some features that have major changes. For example when upgrading from V2.4, you should upgrade to the last version of 2.4 first.

How much free disk space do I need when upgrading to higher version?

You need space for the system package and the additional packages you have to upgrade. After uploading the newer version packages to the router you should have at least 2MB free disk space left. If not, do not try to make the upgrade! Uninstall the unnecessary packages first, and then upgrade the remaining ones.

Downgrading

How can I downgrade the CableFree RadioOS™ installation to an older version?

You can downgrade by reinstalling the RadioOS™ from any media. The software license will be kept with the HDD as long as the disk is not repartitioned/reformatted. The configuration of the router will be lost (it is possible to save the old configuration, but this option has unpredictable results when downgrading and it is not recommended to use it).

Another way is to use the /system package downgrade command. This works only if you downgrade to 2.7.20 and not lower. Upload the older packages to the router via FTP and then use the /system package downgrade command.

TCP/IP Related Questions

I have two NIC cards in the CableFree router and they are working properly. I can ping both networks from the router but can't ping from one network through the router to the other network and to the Internet. I have no firewall setup.

This is a typical problem, where you do not have routing set up at your main Internet gateway. Since you have introduced a new network, you need to 'tell' about it your main gateway (your ISP). A route should be added for your new network. Alternatively, you can 'hide' your new network by means of masquerading to get access to the Internet. Please take time to study the Basic Setup Guide, where the problem is described and the solution is given.

There is an example how to masquerade your private LAN:

[admin@CableFree] ip firewall nat> add chain=srcnat action=masquerade out-interface=Public
[admin@CableFree] ip firewall nat> print
Flags: X - disabled, I - invalid, D - dynamic 
 0   chain=srcnat out-interface=Public action=masquerade 

How can I change the TCP port number for telnet or http services, if I do not want to use the ports 23 and 80, respectively?

You can change the allocated ports under /ip service.

When I use the IP address/mask in the form 10.1.1.17/24 for my filtering or queuing rules, they do not work.

The rules 'do not work', since they do not match the packets due to the incorrectly specified address/mask. The correct form would be:

   10.1.1.0/24 for the IP addresses in the range 10.1.1.0-10.1.1.255, or,
   10.1.1.17/32 for just one IP address 10.1.1.17. 

I need to set up DHCP client, but there is no menu '/ip dhcp-client'.

The DHCP feature is not included in the system software package. You need to install the dhcp package. Upload it to the router and reboot!

Can I statically bind IP's to MAC addresses via DHCP?

Yes, you can add static leases to the DHCP server leases list. However, DHCP is insecure by default, and it is better to use PPPoE for user authentication and handing out IP addresses. There you can request the user to log on from a specified MAC address as well.

How can I masquerade two different subnets using two different external IP addresses for them?

Use /ip firewall nat rule with chain=srcnat action=nat, specify the to-src-address argument value. It should be one of the router's external addresses. If you use action=masquerade, the to-src-address is not taken into account, since it is substituted by the external address of the router automatically.

I cannot surf some sites when I use PPPoE.

Use /ip firewall mangle to change MSS (maximum segment size) 40 bytes less than your connection MTU. For example, if you have encrypted PPPoE link with MTU=1492, set the mangle rule as follows:

 / ip firewall mangle 
 add chain=forward protocol=tcp tcp-flags=syn action=change-mss tcp-mss=!0-1448 new-mss=1448

Bandwidth Management Related Questions

How can I controll bandwidth(bandwidth shaping)in Bridge mode?

In bridge settings enable use-ip-firewall.

Can I use CableFree as a bridge and a traffic shaper in one machine?

Yes. You can use all the extensive queue management features. Set the queue to the interface where the traffic is actually leaving the router, when passing through the router. It is not the bridge interface! The queue on the bridge interface is involved only for the traffic generated from the router.

Can I limit bandwidth based on MAC addresses?

For download:

   1. connection-mark all packets from the MAC of each client with different marks
   for each client using action=passthrough:
   /ip firewall mangle add chain=prerouting src-mac-address=11:11:11:11:11:11 \
   action=mark-connection new-connection-mark=host11 passthrough=yes

   2. Remark these packets with flow-mark (again different flow-marks for each connection-marks):
   /ip firewall mangle add chain=prerouting connection-mark=host11 new-packet-mark=host11

   3. We can use these flow-marks in queue trees now.

While this solution should function, it is fundamentally flawed as the first packet of each connection destined to these clients will not be taken into account.

For upload:

   [admin@AP] ip firewall mangle> add chain=prerouting src-mac-address=11:11:11:11:11:11 \
   action=mark-packet new-packet-mark=upload
