Problems accessing PgSQL trough a VPN

Hi,

I've a "little" problem while trying to access any pg database trough our
VPN. It simply refuse the connection. Otherwise, The connection works fine
on our server put in the DMZ with a classical connection.

Our setup is:

client: Eclipse with a JDBC driver trough VPN
server: Pg SQL 7.4.2 with a pg_hba.conf where I put such line: host all
all 192.168.2.1 0.0.0.0 md5
Ther is no integrated firewall and the server is in a LAN, protected by a
firewall.

All the other connection such as SSH works just fine trough the VPN.

Any ideas?

Thanks in advance.
