Looking for any ideas/thoughts on this as I'm completely fried.
We have a 3300 (on-site) with the following IP assignments:
192.168.1.19 (Applications Suite)
192.168.1.20 (MCD)
172.20.0.0 (All of our IP phones)
192.168.4.0 (Offsite network)
We are setting up an offsite office that will be using softphones over a site-to-site VPN tunnel using Sonicwall routers.
The issue we are experiencing is that the tunnel connects, we can ping everything except for the Applications Suite. We can ping every phone as well. I've been working with our vendor and Mitel support and they are both 100% stumped. The MCD responds without issue. The 192.168.4.0 network is in the list of Local Networks on the server, packet capture from both Sonicwall's show the packets coming in and properly being forwarded to .19. However, .19 never responds. We cannot even access via the web, it just times out.
Has anyone had any experience with this type of issue at all? Any help would be greatly appreciated.
