Question : ISA denying with blank rule

It's ISA 2006.
There's an existing rule for the proxy and this rule has this network named "internal" in the from and to fields which has several of our networks inside it.  

I've added another network to the "internal" network by adding the network's IP range.
However, the traffic from the new network is being denied by ISA even though the rule allows it.

When I go to monitoring > logging, it says it's denying the traffic but the rule is blank with no other useful information.

Does it think it's spoofed or something?

Where can I go to view a more detailed log of this?

Answer : ISA denying with blank rule

Have you added a route add command for the new internal network defined in the ISA server?
