Kaspersky Internet Security and Comodo Firewall..anything I should know??

Hello!
Just wondering if these two play along fine or if something is going on that I need to fix. I am using KIS but with the firewall disabled mainly because I dont want to have to reconfigure everything I set up with Comodo Firewall plus Comodo has been working fine so why bother changing the Firewall?
So just checking with you guys…
thanks!
