I'm trying to confirm the following but can't seem to find the 2 answers that I need. Can anyone help.
We will be using GRE tunnels from remote sites that terminate on 6509 switches in the primary site to get multicast across a providers cloud.
I know that both the 7204 & 6509 that we are using can support GRE tunnelling and have it in place on a test network.
The 2 Questions
1. Does the 6509 with FWSM still support GRE tunnels (I know pix don't)?
2. Can the FWSM inspect packets arriving on the tunnel interface and leaving out a physically routed port or even a vlan interface?
Are you askin if the FWSM supports GRE or the 6500 with a FWSM in it. If the second then yes the 6500 will still support a GRE tunnel.
Could you be a bit more specific in question 2. The FWSM deals with vlan interfaces and bridge groups. You could terminate the GRE tunnel onto a router in a DMZ and then inspect the traffic.
