We've just had BT install our new Leased Line using an 'ADVA FSP150CP' routed to a 'Cisco 2921 ISR' which the engineer has setting as 'straight through'. He's shown us it working (30mb up & 30mb down!).

Our software guys (who manage our routers & configuration) had previously specced and setup a 'Draytek Vigor 2830' for our DSL connection and had chosen it because it has a WAN port for future use... Now that future is here they're struggling to configure the WAN port!

From my reading of the routers specification it almost reads as if the ADSL connection is automatically the primary and it'll only fallback on the WAN connection if the ADSL link drops?

◾Secondary WAN Port : Gigabit (1000Mb/s)) Ethernet for load balance and WAN failover
Click to expand...

I've setup the WAN connection as best I can on the Vigor (we have no details from BT, but the engineer left us the IP addresses it's using). On the WAN screen it shows in Red, the ADSL is in Green. I really must be missing something somewhere?!

Help! Thoughts? :)

Edit: we will be keeping our DSL line active until all email and MX records have been swapped over so this router will need to run both connections (if possible).
 
BT Engineer has given us the IP address range allocated to it.

I'm assuming the 2921 will automatically be using one of them already so setting that IP as the gateway on the WAN connection is correct?

There doesn't seem to be any guidance from Draytek how to configure a leased line on the WAN port. BT do not provide any support on configuring the equipment attached to the 2921 if it is not their own.
 
When I recently configured an EFM connection with a Draytek I just configured the WAN as static and entered the IP Address, Subnet Mask and Gateway IP based on the information provided by BT.
 
We don't have a gateway IP from BT...

Have been given an IP range of 4 and a subnet of 255.255.255.254

The Engineer did mention '29 mask bits'?
 
A /29 would be 255.255.255.248 which would make a lot more sense than your 255.255.255.254.

If it's the same as the EFM I configured (also a /29) then you need to enter the IP of Cisco as your Gateway and the next one is your first usable IP address.

You can then add the additional IPs using the 'WAN IP Alias' button.
 
That would make much more sense (with the IP range given as well!)

Certainly setting the subnet as .248 the router seems to be happier but nowhere can I see how to use 'both' of the lines apart from choosing load-balancing...

Basically our domain MX points to our DSL for mail delivery to our server, we want to confirm everything is working with the leased line before we switch the MX over (we would also be doing a domain transfer, but that doesn't need to happen right away - we may transfer it to our web guys instead).

Again I can see nowhere on this router to configure any kind of connection 'priority'. I do see a mention within the load balancing about balancing by 'line-speed' but the WAN2 connection doesn't have a line speed listed, the DSL on WAN1 does?!

I've plugged a laptop into the 2921 with the IP settings listed to confirm it's connected & online - all worked fine! Just stuck at the final hurdle of configuring the existing router! :(

Weekend to think about it anyways, thanks for the insight and input so far bremen! :)
 
If you're hosting a mail server you must have opened/forwarded the necessary port(s) on the Vigor. In the port forwarding rules you can choose which WAN the rule applies to. So get your MX DNS updated and then update the port forwarding rules.

If you want to force outgoing traffic through WAN2 then use the settings under 'WAN IP Alias' so that only IP(s) from the new connection have 'Join NAT IP Pool' enabled. It's best to only have a single IP selected to avoid confusing some web services.

Don't forget to get your rDNS updated to point to the new WAN IP.
