Hello Mark,

Yes, it's true.

The timeout setting can be changed in configuration file. Stop Winroute, edit the "winroute.cfg" file and search for the following values (they are in "Firewall" section): DefaultTcpTimeout and DefaultUdpTimeout. Timeout can be in minutes, default value is 40 minutes for TCP and 8 minutes for UDP protocol. However, there are some services with different timeout which cannot be changed (DNS, FTP, SNMP, NTP).

Please be sure, you know WHAT you are doing and WHY you are doing it.

hi. thanks for that. i will trz this.
we are using a voice transmitting software which uses a udp port. if one side doesnt transmit for a longer time, no connection can be established. i hope this solved our problem.

Does your voice software use SIP or H.323 protocol?
KWF is able to handle these protocols and allows VoIP software to run from behind the firewall transparently.
