ASA to to terminate ipsec and anyconnect connections + SNMP on single loopback

[Rajesh Hirani]

The router (800 series) that is being replaced with the ASA sits behind a point to point connection behind the landlords router. They have provided one public IP which has been configured as loop back interface. The loop back interface has NAT enabled for hosting internal SMTP etc. The loop back interface is also used to terminate ipsec and any connect connections.

Can ASA support such configuration? 

[S-Lemming]

Unfortunately not, ASA does not support loopback interfaces. 

Also the IP terminating VPN's is always the outside interface IP of the ASA.
