Parallel VPN Tunnels?

« on: March 05, 2010, 11:49:25 AM »

We have a requirement to set up two concurrent IPSec VPN’s between the same 2 devices.

Al the central site we have an NS-5GT with trusted network 44.0.0.0/8 and DMZ 10.0.0.0/8

At the remote site we have a Billion Bipac 7402GX ADSL Router with a trusted network 192.168.60.1

Both devices are on fixed public IP addresses

The requirement is to tunnel to both the 44 and 10 networks from the Billion end

The limitation is that the Billion can only tunnel a single subnet down a tunnel so it needs two tunnels set up – one for 10 and the other for 44

On the 5GT we have set up a single Phase 1 Gateway and two AutoKey IKE tunnels with associated bi-directional policies (Policy Based VPN)

The problem is that we can only have one VPN active at a time. If the VPN to 44 is up then the VPN to 10 fails Phase 2 & vice versa

Does anyone know for to fix this?
