Dual WAN Question - 2925 was created by ronniem
Hi there
Having recently turned away from Netgear (who have an unresolved firmware bug in products that can act as a VPN endpoint) to Draytek products, I need to establish if the following is possible.
Current Setup :
We have a site that has two Satellite broadband services, each having it's own main purpose.
Each Satellite service has its own router, only one does DHCP, and they both feed the same LAN subnet via a switch.
All computers have static IP addresses, and their internet traffic can be routed through either Satellite service, simply by pointing the machine's "gateway" at one or other router.
Question 1 :
Is it posssible to replicate this functionality using a single Draytek "Two WAN" 2925 model ?
Question 2 :
The Draytek resource material talks of load balancing and failover, but . . . . .
If we wanted to change to two separate subnets, one fed by each Satellite service, (possibly sharing hard wired network) can a single Draytek 2925 be configured to support this ?
Thanks for any words of wisdom !!

Are you looking to replace the two satellite routers for the 2925 or keep them and connect to the drayteks respective WAN ports?
Either way you can create two VLANs on the 2925 and make it the default gateway for each LAN then use polices to route the traffic.
Within each policy you can then use the failover option in case of failure

Sorry . . . . I should have made it clear that we intend to remove the existing routers and replace them with a single Draytek router.
Each Satellite service has a Satellite modem, which would feed one of the WAN ports on the 2925.
Thanks for this, and the very helpful image.
So . . . . my understanding is :
That you can create a VLAN and have it use a defined WAN port.
. . . . . in which case it looks easy to achieve our aim.
Is this understanding correct ?

Yes you just need to make sure you have the load balancing rules set correctly
Source of LAN1 Subnet to go via WAN1 and source subnet of LAN2 to go via WAN2.
I would set up your VLANs first and make sure you can get the internet etc with both Satellite modems plugged in to the 2925 then once you are happy its all working as standard start with the route polies.
Are you going to use tagged (dot1Q) vlans or just port based? (How are you going to configure the switch they are all sharing?)

Don't know yet is the honest answer !!!
There is a managed switch already in situ which can generate VLANs and have its physical ports allocated. The physical network is distributed to the building from this switch.
We may be able to utilise one ethernet cable for one subnet, but it is possible that we may have more than one subnet using one cable. if we end up "cable sharing" I guess we need to pursue the "tagged VLAN" route ?
Thanks for your help.

Yes you will need to use tagged VLANs if you are trunking. Failing that you can just go port based on the router and use separate switches for each LAN
