IPSec tunnel from Vigor 2900 to ZyXEL ZyWall 35

Today I connected some Vigor 2900's to a ZyXEL 35 using an IPSEC tunnel. The Zyxel settings are unchanged from my blog of 29/01/2006.

Firstly a version check of the kit I'm using:
ZyWALL 35 : V4.00(WZ.5) 01/06/2006
Vigor 2900 : 2.5.6

I've screen dumped the configuration pages below. The network IP address of the ZyWALL network is 192.65.100.0/255.255.255.0. The network address of the Vigor 2900 network is 192.168.65.0/255.255.255.0.
