I have a customer requirement where the following scenario would be ideal. Can anyone confirm whether by having a 2950 at each site this is possible?

Main Site
2 x ADSL connections into Draytek 2950 (all static IPs)

Remote site 1
2 x ADSL connections into Draytek 2950 (all static IPs)

Remote site 2
2 x ADSL connections into Draytek 2950 (all static IPs)

Continued service is of highest priority, with performance also being important.

Main office WAN1 call Remote site 1 WAN1.
Main office WAN2 call Remote site 1 WAN2.
Main office WAN2 call Remote site 2 WAN1.
Main office WAN1 call Remote site 2 WAN2.

I guess I need to use the Load Balancing feature here, which would also ensure connectivity continues in the event of any one connection going offline for a period of time?

Can anyone confirm this would work? Or what I need to do? Before we spend £1000+ on hardware.

Thanks for any help/advice...

How's the LAN side setup? One subnet on each site?

Yeah, each site is on it's own subnet.

Main 192.168.16.0/24
Branch 1 192.168.20.0/24
Branch 2 192.168.30.0/24

yes is the answer, but guess you prob know by now.

there's also a vpn failover & load balance feature on the 2950's but i've never had a chance to try it.
