I am trying to configure ASA 5505 as SSL VPN server. I have a range of public IP addresses from service provider. I am using interface vlan 2 (outside) IP address for our internal Exchange server which uses port 443, 80 and 25. I want to use another available public ip address for SSL VPN, but it seems it's impossible. when I run wizard, it only lets me to specify interface which it's already used for PAT.
if you suggest me how to accomplish this task, I'll be very appreciated.
Since you need the actual interface to terminate SSL VPN or any other VPN I would suggest to use a different pub IP that you have available and cutover the rules that you have configured for your exchange server that is using the ourside interface as static PAT for 443 and use regular static nat for exchange services , you need the actual interface to terminate the vpn ,..AFAIK ASA does not support secondary IPs on the same interface .. like you could on a router.
