comodo won’t allow my desktop to reconnect coming out of sleep or if there is a temperary interuption of the connection. I had to set the security level to allow all and repair the connection. This has only start in the last few weeks. I have been using it for 5 months and didn’t have this problem. Can anyone give me any insights?
I think I can confirmed that. I’ve only had my computer in sleep mode once since I installed Comodo so I wasn’t sure this was the cause. I think the Comodo Firewall isn’t the best solution for nonstatic IP addresses. Lot of tinkering to get it to work, but I’m gonna stick with it a little while longer to test it.
I had the same problem, worse: I even needed a full reboot after coming out of sleep or stand by. But with the help of Comodo I discovered my configuration wasn’t right.
The easy solution (which worked for me) was provided by a video tutorial on basic installation:
(It has to be said that I had to uninstall and reinstall CPF in order to get this solution working)
If you want a more indepth explanation or if you want to configure CPF’s network control rules manually you have to look in the forums:

Hopefully it will work for you too
If not: you’d better contact Comodo than me
