I found this in the packet filter log of the server that is not letting the app through: Date/time/source-ip: [normal] destination-ip: 66.212.233.228 Protoco: Udp param#1: 137 param#2: 137 filter-rule: BLOCKED Interface: [normal] It is not there on the server that works. Also I have no protocol rules setup for this protocol on either server. I have not touched the filters from their default. Any ideas? -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: June 6, 2004 11:21 AM To: [ISAserver.org Discussion List] Subject: [isalist] Re: Trouble shoot Protocol Defn http://www.ISAserver.org Look in the ISA logs. If ISA is the one blocking the traffic, the logs will say so. Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles!

Now an app wont' work (pokerstars.exe TCP-26002). I then built another server with what i assume exactly the same except its on win2k3, created the protocol rule and it works fine. The app only uses that one port and port 80 so i haven't even a clue where to look for problems.... On my machine I tell the FWClient to use the production ISA - no work, change to test server, connects no prob. I have removed my default gateway. I have defined the Protocol Rule to specifically allow my client IP on both servers. Prod server ISA 2000 SP2 FP1 Win2K SP4 Any clues as to what to check?
