the firewall is blocking the Internet

Hello, I installed comodo firewall.
When I am at home, the Internet works well, but when I came to work and chose a “work network” in the firewall, the Internet doesn’t work.
When I turn off the firewall, the internet works well

I get the same with Microsoft Edge. I can not found the rule who blocks Edge. The option witch I use is modified security rules when I switch to safety modus it works fine.
I imported an configuration backup witch i made a while ago but the problem exist. Even no popup when i use the modified security rules from comodo when I start Edge. There is also no rule to found from Edge in ‘application rules’ witch block Edge. Sorry for my English, hope you understand the problem.
