Entry- and Exit-Gateway can be identical

[wiiinnie]

Expected behaviour Expect to have different Entry- / Exit-Gateways selected

Yep, from the system perspective there is no reason a gateway can't act as both entry and exit for the same client. But I think we want to guard against this happening in the gateway selection process in the vpn client
