Cisco Pix 520 - Open Ports

How can i see what ports are open on my Pix 520?
1 Solution
You want to sh run check for access-list permit statements, and also then verify they are open by looking for access groups that apply the access-list to an interface.

ACLs dont open the ports necessarily, they need to be applied to an interface.
please post a sanitized config and we can help out.
To add on to TMekeel's answer above, If you don't have ACLs applied to the interfaces (show run access-group and see if acl's are assigned), then the rules of traffic will be governed by the security interface number.  No ACL needed to get traffic flowing from a higher numbered security zone to a lower numbered security zone, all that traffic will be implicitly allowed when no access-list is applied via access-group command.
