I have a new Linksys WRT110 router (has built in firewall) and just redid harddrive. CIS firewall needs to be disabled to get a connection due to the built in firewall in the router…I didnt have this issue in my old 110 router, is there a fix so both firewalls are active and they dont keep pinging each other >…

PLEASE HELP ME

What do you mean with redid my hard drive? Do you mean you got a new one and freshly installed Windows?

What OS are you on and what other security programs do you have running in the background?

Can you show us screenshots of your Global Rules and Firewall logs (Firewall → Common Tasks → View Firewall Events)?
