Question : How to connect a D-Link Modem to a Draytek Vigor Firewall

Hi guys,
I am looking for some advice on how to configure a D-Link ADSL ethernet Modem (Model DSL-320B) to a Draytek Vigor 2910 Dual-WAN Security Router.  I setup the modem to our Pipex connection simply by choosing PPPoA and putting in our Pipex username and password. (I also turned off DHCP as I am connecting it into our network which already had a DHCP server).  This works so far.  

Now comes the problem.. I want to connect it to the Draytek firewall.  The draytek does not have the setup option of PPPoA.  It does have Static IP option(which I do have a static IP with this Pipex Connection).  I have also just upgraded the firmware of the Draytek so it's up to date.  But I cannot get the Draytek to see the modems connection to the internet.  Do I have to use bridging mode somewhere?  Not sure what that is but someone said it might be that..  Bit out of my depth here so any fool proof advice would be great :-)

Cheers

Paula

Answer : How to connect a D-Link Modem to a Draytek Vigor Firewall

I don't have any direct knowledge of those products, but I may provide some insight.

If the Draytek don't have any PPPoA options, my guess is you should use the PPPoA on the D-Link as it is.  Bridging is for letting the firewall take care of the PPP stuff.

If you set up the D-Link to forward everything from the outside to the Draytek, and set the default gateway of the Draytek to the D-Link, it should work.  As long as the D-Link does not do DHCP anymore, this probably needs to be configured manually.

As long as the D-Link is doing NAT, you should not set up NAT on the Draytek, as double NATing is nothing but trouble.

Hope that helps.
