I have a Cisco ASA 5510 with 4 interfaces. I am using one as my outside, one as my inside, one for internal wireless guests. I have an extra that i would like to use for my VPN traffic so that it does not touch my outside interface. I have a block of 16 public ip's. One is assigned to my outside interface already. I want to apply a different addy to my VPN interface. The asa throws up an error when trying to configure an ip address because it overlaps with the outside interface subnet.
Can you give me direction on how i can make this happen?
