Watchguard BOVPN problem

Hi,

We have a head office and a satellite office, connected through a VPN, for network traffic. This is working fine. We have an Avaya IP Office telephone system in head office and would like to use 5 x IP phones in the satellite office that connect to it. The phone network in head office is on a separate IP subnet  / VLAN to the main network. We are struggling to get the phones to work over the VPN.

Setup is as follows:

Head Office
Watchguard XTM330 Firewall (Main Network 10.1.0.0/24, VLAN1) (Phones 192.168.25.0/24, VLAN 5)

Satellite Office
Draytek 2860 (One Network 192.168.101.0/24)

We have our VPN configured as a LAN to LAN on the Draytek with both subnets added under Network settings, and their diagnostics show that traffic destined for the phones network in head office does route through the VPN. I don't think that we have the Watchguard (uses BOVPN) set up properly to get the phones to connect. The Watchguard acts as a DHCP server for the phones network. IP phones in head office work fine.

Any help to get the phones connected would be appreciated.

Is the phone VLAN terminated on the watchguard, or do you have an internal router ?
Do you have connectivity between the remote office and the main office for the other main office subnet ?
The VPN configuration on both ends needs to include all three subnets.
This question needs an answer!
