Hi.
I've a Draytek 2820n router.
When I set up a VPN to connect this to the HQ all works well when I am using the WAN1 link which is using the Draytek itself as the ADSL modem.
I also have a secondary connection which is connected into WAN2 an ethernet port with a modem mode cable modem on. Browsing can be send over this fine.
However when I try and send the VPN out over this link it is not announcing its public IP address. It presents either the Drayteks local ip (192.168.x.y) or 0.0.0.0 if I switch the setting of "From first subnet to remote network, you have to do" from Route to NAT
