Hi all,

I am hoping somebody can tell me what i am doing wrong here.

I have 3 internal networks connecting to cisco router.

Network 1: 10.10.1.0
Network 2: 10.10.2.0
Network 3: 10.10.3.0

the ISA internal connect to 10.10.1.0 network. IP: 10.10.1.10.

I add 2 static route on ISA internal NIC and i also specify 3 networks in Internal network. That's all i have to do i thought. However, I can't ping to network 2 & 3 at all. Looking at the logs, The ping get denied by default enterprises rule. I dont know whatelse i suppose to do...Any ideas?

Thanks

Danny

Stefaan,

I have a dump question. I continue to see the log where traffic got denied by enterprise default rule. Ex. 10.170.80.xxx to 10.170.80.255 ...this 10.170.80.255 should be part of ISA internal network right? any thoughts? I did include 10.170.80.255 in the IP range.

Thanks

Danny

Hi Danny,

what is the source and destination network and IP's in the log entries?
Is the network ID 10.170.80.0/24 directly connected to the ISA server?
...

Please, more details!
