I am new to ISA Server and now trying to configure. I tried DNS and web yesteray but i got a 403 error when i try to access from outside. Today i want to check simple pcanyhwere connection. I followed the step in accordance with the publised document about publishing pcanyhwere in isaserver web site. Created 4 protocol definitions(tcp,udp,561,5632) and created 4 Server publishing rule pointing towards the public ip address and the private ip address. But when i tried connecting from outside the firwall it did not work. I added the public ip address in the external interface of the ISA Firewall. Is this correct. Should i define something in the Access Policy also for the pcanyhwere to work from outside? Can come guide me in this regard. Thanks in Advance
