Re: ISA net configuration In Vlan and multiple Internals network

Correct me if I am wrong, but this is more of a network aggregation problem?
Is your networks subnet contiguously? If you have contiguous subnet, you
could look into Classless InterDomain Routing (CIDR)/Supernetting. If you
unmask your subnet properly you don't have to setup a default gateway in
each subnet.

HI,

Here is my situation,

1---I have 6 internals network defined behing ISA
2---A trunk link is attached to a GiG interface to the ISA server, this
link
carry all the 6 internals network to the ISA server.
4---I have another link to the external
6---All the internals vlan are defined in a cisco catalyst 6500 serie and
extended to the access switches where hosts are connected, no routing
interface are defined on the 6500, meaning it is only layer 2.
3---Using the Intel Card software, i have created a vlan interface of all
my
internal network on the ISA server
5---For each vlan interface i have setup the ip address appropriate ip
per
vlna interface without a gateway.

Problem: for each of vlans i have setup a permenant default route but it
is
not working.

Question:
Has anyone either comme to this kind of setup, how can i get this setup to
work.
I am looking more specifically on how i have to setup the interfaces and
routing in ISA to get all this working.

Comments:

for the default gateway setup for each vlan, i have left these empty as
Windows have a lot of problem to find its route when multiple gateway are
defined on the box.

Thank you for any suggestion, references, help.

Ralph
