VPN behind NAT on ZyWALLs

Archived from groups: comp.dcom.vpn (More info?)

Hi,

Here is another problem.

I am trying to establish VPN between ZyWALL 2 which is behind a NAT ADSL
router (non static IP) and ZyWALL 70 which is connected through DSL and has
static WAN IP.



I have configured as it is said on Zyxell support webpages but they don't
want to establish VPN tunnel.

In ZyWALL 70 there is an entry saying:

Rule[TEST_VPN] preshare key mismatch with peer



I am sure that keys are correct entered because I have copied it an pasted
it in both devices.



Both routers have the newest firmware.

Any idea?



I can send on private e-mail more detail description and configuration with
logs.



Will appreciate any help

With best regards



Mike
