Hi,

I have a similar problem, internal network with 10.68.37.0 mask 255.255.255.0, after created a perimeter network with 192.168.10.1 mask 255.255.255.0 to recive tree subnets by router cisco, 10.68.47.0, 10.68.46.0 and 10.68.48.0. Ok
New, i can't route with this subnet's, but if i put a Gateway into perimeter a do a ping, horever the isa server give a error with a route 10.255.255.255.

Thank's helio.viegas@algar.com.pt

Hi helio,

If I'm getting this correct you have following setup:

Internal: 10.68.37.0/24
Perimeter: 192.168.10.1/24

10.68.47.0 Internal or seperate network??
10.68.46.0 Internal or seperate network??10.68.48.0 Internal or seperate network??

So what do you want to achieve ??

Hi,
Before i installed isa 2004, i had a isa 2000, i have 3 subnets, 10.68.46.0, 10.68.47.0 and 10.68.48.0, subnet's routing by cisco with internal card with 10.68.37.254 my central and connected a switch, it's worked. Now a learn that isa 2004 does not support traffic redirection, this is my problem, i can't change the subnet's IP. When i installed the isa 2004 with card to recieve that subnet's, all the time give a error becouse the internal card created a routed 10.255.255.255.

Thank's a lot by your interest to help me.

Hi,

This might work:

A) Create static routes on your ISA for each subnet (in the routing table of your operating system):

10.68.46.0 --> Gateway IP adress CISCO
10.68.47.0 --> Gateway IP adress CISCO
10.68.48.0 --> Gateway IP adress CISCO

B) As these will be members of your Internal network you should also add them to your Internal network on the ISA

C) You can safely delete the 10.255.255.255 entry from your ISA Internal network.

Hope this works,

Stefan
