Hi,

Has anybody seen this problem or I have done something wrong?

I have a Vigor 2860n connected to WAN (dynamic IP address provided by the ISP). This router is connected via it's Ethernet port to the WAN1 port of a 2820vn for DMZ connections.

I have configured DynDNS and VPN Remote Dial-in User on the 2860.

Now, if I define the WAN1 DMZ as "None" or "Private IP" on the DMZ Host Setup screen, both VPN and DynDns work as expected in that the incoming VPN connections are established successfully and DynDNS database gets updated by the router everytime it's public IP address changes by the ISP.

However, when I use "Active True IP" for the DMZ link, none of the above work.

Any ideas/suggestions?

Many thanks.
