Hello all. I am trying to find a way to get around the need for Site-To-Site VPN Boxes such as Cisco RV-180s for Work From Home users that my company has been using for years and go to a Firewalla based solution.
I have but a Blue+ behind my Watchguard Firewalla in the main office and here is the main configuration at this point...
Main Office LAN (Watchguard): 10.10.10.x/23 / SNAT to Firewalla Blue+ for VPN
Office Firewalla Blue+ (On Main VLAN) : LAN 10.10.10.150 / Overlay 192.168.100.1 / Limited Mode
OPENVPN Network (On Firewalla Blue+): 10.102.90.1/24
Remote Firewalla Red: LAN 192.168.99.1 / Overlay 192.168.200.1 / DHCP Mode
I have the Blue+ set up as the Site-To-Site VPN Server and I can connect from the Red just fine when I assign clients to the VPN. However, I have one HUGE issue that I can't figure out.
I have a Polycom SIP Phone that is able to register to the SIP Server, but the calls are failing to go through. I have struggled getting SIP to work over SNAT on the Watchguard in the past and the only way it has worked is through the BOVPN Site-To-Site in Watchguard.
I feel like I am on the cusp of this working as the VOIP Phone is a deal breaker if I can't get it working.
Any ideas on what might be causing the calls to fail?
