No, not with IPsec using 'main' mode, the actual IP address is a part  
of the security policy.

Using certificates is a solution, but trunk/0.7 does not support that.

Also a FQDN 'could' be used as an identity, but that requires the use  
of 'aggressive' mode which has security issues, so we chose not to  
support that.
