I am using SBS 2004 with ISA enabled. I am attempting to install back up software (iron Moutain) wich is an off site back up solution. There is a client I install on the server then config it to back up whenever and however. I created a rule in ISA to allow the proper port 1636 out. I can do a tracert and follow the IP its home however the client cannot connect to the server at Iron Mt. Do I need to allow the port IN as well? how can I config that? Is there away to allow specific apps access throught he firewall in ISA? Thanks.
