Hi2all,
I have a Zywall 5 in the head-office and a zywall 2plus in my home-office and I need to establish a vpn between them.
The Zywall5 is connected to DSL by PPPoE (dynamic IP), the Zywall 2+ is connected to Vodafone UMTS by a LinkSys UMTS-Router (dynamic IP).
Vodafone does not route any open ports to me so the vpn can only be initiated by the zywall 2+
I have no idea how to set up the two zywalls so I hope to get a small "howto" from you :-)
Thanks in advance Florian
