We have moved two clients to a new network scheme as follows:


CLIENTS 192.168.1.x
||
||
|| 192.168.1.10
WEB SERVER / TERMINAL SERVER / ROUTER
||192.168.2.10
||
||
SERVERS NETWORK 192.168.2.X


We have thinking about this servers' subnet in order to isolate them to the
main network and also to build a gigabit ethernet between them. There is a
middle server who act as a web server, serves some terminals (clients who
works into it) and also forwards the packets between the two networks (act
as a router/firewall).

All the net configuration is correct, all the network has normal
connectivity, but the software running on the old clients (main network)
seems to have some trouble connecting to the database servers on the subnet
2.x. We launch the program and it "hang" when connecting to the database for
1 minute, then it gets connected and everything works fine.

We have one company running windows servers and the other one on linux. Both
runs the same firebird version (1.5)

On the clients the only thing I've done is add the routes to find the new
subnet and change the database IP on the config files of the old software.
Maybe I've forgotten some step?


Surely this has nothing to do with firebird, but I've prefered ask first
(maybe anyone has found it) before begin mounting various computers,
configure the network and begin testing.


Many thanks,
