If you have telnet access to the router you can login to it and delete the rule that is causing problems. Obviously only do this if you feel confident doing so. Also note that some routers have had telnet locked out, usually by ISPs.
Taken from the Steam FAQ at
https://support.steampowered.com/kb_article.php?ref=1452-HCVB-6984https://support.steampowered.com/kb_article.php?ref=1452-HCVB-6984 and amended slightly.
- Click on "Start", then select "Run", or if run is not present type it into the search box, type "cmd" and press Enter or click "Ok". This will bring up a command prompt.
- Type "telnet speedtouch", or if that doesn't work then type "telnet 192.168.1.254". * **
- You will be prompted to login to the modem with a username/password. The default is one of the following: Username: Administrator
Password: None (leave this field blank)
OR:
Username: admin
Password: admin
If neither of those combinations work, please contact your Internet Service Provider for assistance.
- Once you have logged in, you will be presented with the command line of your modem. This is where you must enter the following commands:
- Type connection bindlist and press enter. This will list connection bindings.
- Look for a line that contains "GAME" and some port numbers. For example: GAME(UDP) udp 27010-27011
- Enter the command :connection unbind application=GAME(UDP) port=27010-27011 and press enter. The port numbers in this command must match the numbers that are listed in your GAME port listing, similar to the example above.
- Try joining a KF game and see if that fixes things. You will have to issue the command saveall to save the changes.
* Note that if the IP address of your router is different then this won't work. To find out what your router's IP address is, open up a command prompt (type cmd into the search or run box as before) and type ipconfig. This should show your currently connected network connection - the router's address should be under "default gateway". If you can't see this, try "ipconfig /all" without quotes. This will bring up all network adapters so you will have more to look through, but you should be able to find it.
** If you do not have telnet installed and get an error message (it isn't installed on Vista and 7 as default), you can either install it through the programs and features -> turn windows features on or off section, or you can use Putty -

I'm not sure if this will cure the router restarting, but after I did this to my test HomeHub it worked fine and didn't reboot at all.
