I would need help with setting VPN to LAN.
This VPN used to be working, but I must reset both ADSL modem and Router/Firewall to factory setting.
Now I am not able to create VPN to small LAN.
VPN clients are Smart VPN clients.

Could you recommend me some resources how to set Thomson SpeedTouch (500) and Zyxell Zywall to IPSEC VPN?

Thank you very much
