I have problem connecting to FB server from a remote PC sitting on different subnet mask. It said "Cannot attach to services manager" everytime I tried to establish connection using TCP/IP mode.

Server IP: 172.30.18.104

Gateway: 172.30.16.1

Client IP: 172.30.0.244

Gateway: 172.30.0.1

Firewall is off at both side.

Port 3050 is opened.

Anti-virus sofware is off.

Local conncetion to database at server is fine.

If I connect from a client PC which resides on the same network segment, it is working fine. I suspect is has something to do with the packet routing or have I missed anything here?

Your help is very much appreciated. Thanks in advanced.
