Cisco VPN with Router

[Jay Somerset]

I use a Cisco VPN to connect to my office network. This worked just fine
for all types of access until I installed a router between my home desktop
and my cable modem. Now, I can log on through the VPN, and access an
Exchange server, but I cannot do a NET USE to connect to my files on an
office server.

The router is a Netgear WGR614, and I can't find anything in its
documentation that tells me how to "escape" this transaction from the
router's built-in firewall.

Has anyone seen and cured this type of problem -- it must be general to most
routers (Linksys, Dlink, etc.) as well as Netgear.

Thanks.

Do you see ipsec passthrough on the router? I would either move the computer
into the dmz or disable the router firewall just long enough to test and see
if it works. If it does you might have to forward TCP and UDP Ports: 135,
137-139, and 445 UDP Port 593 and see if that helps.

Also you might want to check the client, i think there is a NAT traversal
switch (sometimes called udp encapsulation)
