"Unidentified IP traffic" - 30.Apr.2007 4:20:56 PM

I'm using an ISA server within my organization behind a hardware firewall and router.  Its intended use is to proxy web users for internet filtering.  I am using one network card on the server.  Also, I have one firewall access rule that allows any network sources to get to any network destination via any port.

However, my backup software is unable to communicate with the ISA server.  It has a client that installs on the ISA server and operates over port 6123.  I have added user defined protocols to allow incoming and outgoing TCP traffic on that port.  When I try to communicate to the ISA server, it will log "Unidentified IP traffic" as the protocol via TCP transport and the Enterprise Default Rule is responsible with the result code being 0XC004000D FWX_E_POLICY_RULES_DENIED.  This will show up 3 times before the backup server gives up.

I've ran network monitor on both the ISA and backup server, but I'm not sure what I'm looking for.

Why does ISA bypass my rule to allow traffic in/out on port 6123?

Thanks

The ISA Firewall is a FIREWALL. Get a second NIC in that ISA Firewall so that it can shore up the security holes in your "hardware" firewall. Then we'll be able to fix your current problem.

HTH,
Tom
