Comodo won't work with Linksys router

Comodo won’t allow access to the internet when I installed a Linksys Router. Only when I shutdown Comodo can I access the internet. I need to find a way to allow COmodo to work or find another firewall client, which I don’t want to do.

Any ideas?

You should add your router as a trusted network zone. Sorry for not giving you more specific information, but I am using version 3 of the firewall and don’t remember how to do that exactly in v2. Although I think you can find it in the manual. Until someone who is still familiar with v2 answers your problem, good luck.
