Hi All,

Thanks in advance.

I have install server application on one machine(64 bit win 7). it is basically for licensing purpose on local area network. In windows firewall setting i created inbound rule for listening connection request i.e UDP port 5000 and outbound rule for broadcasting purpose.

scenario:-

I am using 64 bit windows 7 professional and windows firewall is on. when client application try to connect to server, it connect successfully but after 30-40 second connection to server lost and it lunch connection error and asking for reconnect.

If i turn off firewall, every things are going as per my expectation.

Note:- above scenario is working fine on window XP.

Kindly suggest what firewall setting need to change in order to get resolve this issue.

your response is keenly awaited.

Thanks a lot for your valuable time.

Same problem with Win XP.
My application, running on LAN server, works with Winsock protocol.
When client connect to server, all is OK, but after 4/5 minuts, connection is lost.
If I disable Win XP firewall on client, all works correctly!
Client firewall hav a explicit rule for appliceation (EXE) and TCP port called.
Server machine has firewall enabled and no problem is rised....
