Hi all, Is there anyone in the house who is interested in spending a bit of time trying to help me figure out what protocol or application filter I need to allow a client application to pass thru ISA. I am trying to allow the hotline client to pass thru ISA, as it stands now I can connect to servers and chat, read and post news etc. I cannot upload or download to the server. I have tried everything I can imagine, but it still will not work. Anyone interested in this problem ? Regards, Mark
