Draytek Vigor 3300v and BT Broadband

[Flying_V]

Help i'm stuck!

We've got this firewall and I need to get it working with our BT Business Broadband router. The router picks up our broadband fine, everything is automatic and it has a sticky IP address from BT for security reasons. We've been given a public IP address for the router and 5 more static IP's.

So everything works ok, I know want to run everything through the draytek firewall. I have a LAN and WAN side to the firewall. The LAN side makes sense to me, I just use private IP addresses in the range of my network. On the WAN side, i'm not sure whether to use public IP addresses or just put the private IP address of the BT router so they can talk to each other?

Does anyone have any idea what i'm doing wrong? At present I can't get past the draytek to the bt box and get online.

Thanks got it working in the end. The range of public IP addresses needed to be added to the WAN interface, so we just set that as DHCP and the BT router issued them to the draytek.

The only other problem was the BT router freaking out due to the number of connections from clients, but we turned that option off as the draytek can handle it. Just need to put our SDSL line on it now and we're done!
