Nortel Contivity to MS ISA VPN server

Archived from groups: comp.dcom.vpn,microsoft.public.isa.vpn (More info?)

Hi,

Wonder if anyone can help or shed light on this one for me.

I've a working Nortel Contivity VPN solution, allowing me to VPN into
our corporation network - no problems.

However, within our corporate network sits my section and we're
firewalled off with PIX's using NAT and an ISA 2003 server, with one
interface, mainly for proxy stuff. In our secure part of the network
we've DNS / AD etc. etc. Worth noting we use the 192.168.0.0 address in
our section and 10.0.0.0 corporatley.

What i'd like to do is VPN in the Corporate network, then use ISA2003
to VPN in my section so i can login to AD etc. etc.

I've created the VPN stuff on the ISA server (allowed VPN clients to
access all internal and external networks) and configured our PIX to
let any traffic inbound or outbound from the ISA server.

on my PC at home i've setup the MS-VPN client, and can get
authenticated and issued a 192.168.x.x IP address from my section DHCP
server. I can even resolve DNS names. But that's it, i can PING,
TELNET, SNMP etc. etc.


Apologies for the essay.

Yours.

Flanshaw Guy.
