1. External interface entry on LAT has now been removed. (hasn't helped!!??) 2. We don't host the web server which has the SQL database on it but we know their side works, its just our ISA server in between that is the problem. 3. In regards to the rules, I though I had these defined perfectly but if its still not working, then maybe I have done something wrong... Do I just make a protocol definition and then make a protocol rule to apply that definition? Ports 1433 and 1434? I have firewall client and secureNAT clients configured. All platforms are Windows 2000 server. Looks like I could be in for an all-nighter...... I will supply any info that is needed to help you guys with this, as your help is greatly appreciated.
