Please excuse my ignorance, but I am new to ISA server and am having great difficulties in configuring it to allow access to the internet for my firewall clients, but also blocking incoming requests as appropriate as to make my network secure. I appear to be able to get the network secure in regard to external access, but in doing so, I am blocking any outgoing requests. If someone has a tutorial or can offer some advice I would be appreciative. I am only wanting to allow MSN Messenger, mIRC, ICQ, and Real Player. All other internet access needs to be restricted. Thanks in advance. Justin Annear
