Hi all,
I just recently received a new Cisco 1800 and have starting configuring it in a test environment. I am not terribly familiar with these combined router/firewall deals, and have only limited experience with 2600 routers and PIX firewalls. I am configuring the 1800 through the web browser and am trying to create an outside interface inbound acl. Essentially, my test ACL looks like this:
permit any any echo-reply/icmp
permit any any unreachable/icmp
permit any any time-exceeded/icmp
permit any any source-quench/icmp
deny any any ip
My problem is that this cuts off my internet activity. My question is how do I go about creating a secure outside_inbound acl and still have my internet traffic. I know I am missing something simple. All my inside_outbound are permit any any ip at this time.
