Are you sure the "little routers" can't be changed?

I ask because we had the same issue here, though not with MS VPN.  If it's a
Linksys 4 port type, the LAN address can be changed by using the Status tab
(I think) on the router config page accessible from your browser.

One then has to think through some network allocation issues depending on
how many people you have.  Do you give each person a /24 like 192.168.25.0?
etc.

Subject: [fw-wiz] Pix and W2K VPN


Hello Wizards,

I am trying to setup a W2K VPN server have only
partially success. If I establish a static route
(inside,outside) on the Pix and open port 1723 and gre
things work just fine. Problem here: The remote
clients use routers at the home offices which only
support the basic 192.168.1.x network - unfortunately
the same class c IP range I have on my office network
and those little routers cannot change theirs. Result:
routing at the client side messed up
Any idea how to solve this?

Same scenario but I use a multihomed server for the
W2K vpn - one Nic connecting to the dmz and the other
to the inside. However - no matter what I try I am
unable to connect to the NIC on the dmz (all ports are
open both ways 47/gre and 1723). Any idea why the Pix
does not let this go thru (I tried telnet on port 1723
- no luck).

I am open for some suggestions as I do not like to
place a NIC on the outside of the firewall.

Thanks!

Christoph

PS: W2K SP2 and Pix 515R 4.4
