VPN over Vodafone 3G / Vigor 2800 was created by brannan
We use a Vodafone E172 3G dongle as broadband backup on our Vigor 2800 in head office.
The failover works well for web surfing traffic - after 20 seconds we are back online over 3G.
However we cannot get our LAN to LAN VPN working.
Anyone know what we should be doing?

Is the 3G site getting a proper public IP address from the ISP ?

Is it the dial-out end which is using the 3G, or the dial-in ?
