Zywall USG 20 site to site VPN


I'm attempting to setup a site to site vpn using 2x Zywall USG 20's. Each location has a static ip, site 1 uses a netgear router for internet access and site 2 uses a tp link modem. Both site have access to the internet.

On each USG 20 I have configured a VPN gateway using the sites external ip in the domain name/ip section under My Address and the remote sites ip under peer gateway ip address.

Most other config for the gateways I have left the same other than a preshared key. Nat transversal is on (have tried it off) Encryption I have left as DES to make it as simple as possible for the time being.

I have then setup a VPN connection on both USG's using the VPN gateway I have created for each site. Under policy I have Local Policy LAN1 and remote policy set tot he subnet I made for the other site.

Encryption I have again left on just DES, Encapsulation is Tunnel (default) zone is set to IPSec VPN.

Whenever I click connect from either end I get a box saying "dialling" and after 20 seconds it times out.

I have tried many difference combinations of all different settings, double checked ip addresses and searched for hours on the internet to no avail.

Any help would be much appreciated.
