We have an ASA5520 with 3 active VPN connections, currently with one active Public interface on a DSL link (8 IP addresses), and an EOL PIX 515 VPN with 7 VPN connections on another Public network (10Mb connection, Class C network).
We need to migrate the VPN tunnels from the 515 to the 5520. I would like to create a new Public Interface on the 5520 in the 10Mb Class C pool, and migrate the 515 tunnels over to this, then move the 3 existing VPN tunnels onto this 10Mb network. Finally, decommission the DSL link and interface.
First, can the ASA5520 support VPN configuration with 2 separate Public IP interfaces, and Second, if this is possible, could I get a configuration example of this setup?
