Avaya IP Office & Phone Manager on different subnets

[klubar]

We have an Avaya IP Office IP500 (software V4.1)that I recently moved to it's own subnet. The IP Office is on net 192.168.1.0/24 (IP Office assigned address 192.168.1.31). All the phones and voicemail server are on the same subnet and everything is working fine.

From my PC on subnet 192.168.10.0/24 I'm able to access and configure the control unit via IP Office Manager without any issue. I can ping the IP Office unit at 192.168.1.31. And the voice mail server on the Phone subnet is able to see our email server on the PC subnet.

My problem is that IP Office Phone Manager (the end-user program) will not connect to the Control Unit. I've entered the IP-Address in the Unit Name\Ip-Address field and when I click "User List" I get "Unable to Connect to 192.168.1.31". I've opened our router/firewall that connect the subnets to enable access from our PC LAN to the PHONE LAN and vice versa.

I've changed the IP Route -> 0.0.0.0/0.0.0.0 to point to Gateway IP Address 192.168.1.1 (the router) from 0.0.0.0 with no apparent effect.
Packet capture on the PC Network (my IP is 192.168.10.182)
IP 192.168.10.182.56118 > 192.168.1.31.69: UDP, length 24
IP 192.168.10.182.56118 > 192.168.1.31.69: UDP, length 24

And on the PHONE side

Is there anything special that needs to be done on the IP office? Perhaps in the LAN settings do I need to do anything with RIP Mode (currently set to None)?

Windows firewall settings.

If the router/firewall is a sonicwall, that's probably it

Use both LANs. LAN1 connected to the 192.168.10.0 subnet and LAN2 to the 192.168.1.0 subnet.
Remove the routing in the router, it is not needed. In fact it can screw up things.
Then PhoneManager can connect to the IP Office in the 192.168.10.0 subnet without a problem.

If you get it working as it is now then only ten PhoneManager are able to receive BLF status messages.
For sure the customer will not be happy with that.
