Hello all, can anyone give me a definitive answer on this? Recently the clients behind our ISA firewall were set up to use the FW client on each of their respective workstations. However, due to some problems with another Telnet application I have removed the firewall client. At this stage I would suspect that outside email, (where the local email client goes to an ISP mail server to retrieve POP mail) would not work. But it does still work using only the web proxy client. The email still goes out and comes back no problem. Am I missing something that the web proxy is supposed to do this? I had always thought that only the firewall client would allow winsock apps to go through the ISA server. Any ideas? Thanks Peter
