I have about 20 vlans with 6509 connecting to the ISP router.
I intend to bring it an ASA 5510 firewall and have it do VPN for my external clients. I want the 6509 to be the main link to the ISP router.
I wan to use my private address space on the ASA interfaces(outside and inside)
My question to the expert is, can this be done easily? Can someone explain to me without necesarily providing me the commands, how ot achieve this? The ASA would have something like 192.168.40.4 for the inside and the 192.168.41 for the outside interface. The 6509 does intervlan routing and is connecting to the ISP router on say 172.16.30.36/29
I am not allowed to use any of the addresses on the 172.16.0.0/16 space on the ASA.
Can someone please help?
