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.
I can send on private e-mail more detail description and configuration with logs.
Will appreciate any help
With best regards
