VLAN over VPN, is it possible?

Question

Dear experts,

We have a local LAN connected remotely using an IPsec VPN...

Since we are using windows clustering service, we need to create the heartbeat interface
to be transparently connected. We would like to establish a VLAN between the two sites.

On both sites, the Astaro is on a Virtual Machine (ESXi) with the INTEL/Pro NIC.

Is it actually possible to establish a VLAN going thru the VPN?

Thanks a lot!

Hi Bob, 
 Even if the VLAN tag is stripped off from the packet, the UTM will still forward it on the basis of destination IP address/network on Layer 3. When the receiving UTM see's a packet for VLAN network it will add the tag and forward thorugh the respective interface. I think defining the remote and local network in the IPSec policy, should do the job. 
 Let's await reply from Neko once he test's this scenario. 
 Yes, XG do RED tunnels. 
 Thanks
