That should not be an issue for pg_hba.conf - although you must make
sure that requests coming from your virtual LAN are allowed.
On the other hand, the main configuration option you should properly set
is 'listen_addresses', which specifies on which interfaces/IP addresses
PostgreSQL is listening for incoming requests
(http://www.postgresql.org/docs/current/static/runtime-config-connection.html).
I hope this helps.
Ciao,
Gabriele
