I'm trying to setup a PIX 501 behind a 3G Router (Linksys WRT54G3G) as follows:

| 217.174.88.nn (static IP)
-------------
| 3G Router |
-------------
| 192.168.10.1
|
| 192.168.10.2
-------------
| PIX 501 |
-------------
| 192.168.215.1
| Internal network
--------------------------------

The reason for using the PIX is that we want to setup a site-to-site VPN between our
192.168.215 network and a nother remote network.

The 3G router is configured to use VPN pass-trough and to forward
ports 1723, 4500 and 500 to 192.168.10.2.

I can't find any references if/how this can be done. Any advice or hint's
on how to configure the PIX for a setup like this would be great!

Thanks,
/Janne

PS. My current PIC setup follows. As far as we can see the tunnel is created,
but we can't ping the remote site...

Why not just replace the WRT54G with the PIX as the Internet gateway, and use the WRT54G as a pure wireless access point/bridge? Then you don't have to double-nat through the PIX, or forward anything through the Linksys.

>forward ports 1723, 4500 and 500 to 192.168.10.2.
You don't need 1723 for IPSEC.
Make sure 500 and 4500 are UDP and not TCP
Add this to the PIX:
isakmp nat-traversal 20

>access-list 100 permit ip 192.168.215.0 255.255.255.0 host 172.32.100.20
So you're only trying to access one single host on the other side of the VPN tunnel?
That side must be setup with a mirror image of the access-list (assuming it is also a Cisco end point)
access-list 100 permit ip host 172.32.100.20 192.168.215.0 255.255.255.0

hi,

did you resolve you problem ?

I have the same issue. I plugged an asa5505 behind the WRT54G3G and i can connect the vpn but i can't access to any servers...
Where as it works well if i plugged the same asa5505 behind and ADSL router.

Thanks for you help

regards
