Hi there, I have a situation with a customer who has an ASA 5510. They have a fairly standard config with an Internal, DMZ and Outside interface, with rules on the Internal and Outside interfaces primarily. What they want to do is set up a guest wireless network. What I want to do is split the Internal interface into 2 sub interfaces - one with the same settings as the current Internal interface and the other in a second VLAN for the guest wireless traffic. In order to do this though I have to remove the current config from the internal interface. The big question mark for me is what happens to all the firewall rules for the current Internal interface when I remove it? Do they all get deleted? do they revert to Global rules?, do they remain unchanged ready to be applied to whatever interface is named as Internal in the future? (That's what I'm hoping for) One other thing, if I put the second sub interface for the wireless guest trafffic into VLAN 2 that is effectively enabling 802.1q right? Frames tagged for VLAN 2 will go to the second sub interface and native VLAN 1 will go to the Internal sub interface right? ... View more
