Hi Tladi, if the ISA server is setup as a default gateway you should be able to. However, if it is not you will not be able to. If the the ISA is the default gateway you need to add a protocol rule to allow you computers to connect out. You might also need a packet filter rule if you have packet filters enabled.

Before I put the ISA server they were able to telnet out or even send email outside using mailx. Ever since the ISA server was put in place they havent been able to do some of these things and I am actually under too much pressure to have this work. This worst case scenario is I'll have to disable the proxy server. Please help out.
