Cisco router 881G
Posted on 2012-03-10
I have an 881G with an internet connection. I have an ACL on the router applied inbound on the outside interface.
Traffic will overload out the outside interface.
I find that I have to allow ANY tcp inbound to the outside interface or web browsing does not work. I tried just www, and 443 but that doesnt work. Is it because web traffic goes outbound on port 80 or 443 but comes inbound on a high port?
Is there a way to make the router stateful like a firewall?
