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


|

| 217.174.88.91 (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 an a nother remote ntwork.


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

Successful establishment of the VPN tunnel requires that the tunnel end points agree on common parameters for each phase. The parameters include encryption type (Advanced Encryption Standard [AES], Triple Data Encryption Standard [3DES] and DES), authentication mechanisms (pre-shared keys as opposed to certificates) and lifetimes. If these parameters do not match at both ends, the tunnel is not established and you receive the atts are not acceptable error message.
