I have an OpenVPN server running on an untangle/ARISTA device (A). It has a site-to-site connection with another untangle/ARISTA device (B). Also connected to that (B) is an IP-restricted modem. There is a similar modem (same IP restrictions) off-site that has a third untangle/ARISTA device (C) that has a site-to-site cred for VPN server.
I’ve tried a few variations in the config, routing, NAT settings, etc, but haven’t been able to get C to tunnel to A. With the number of factors in the equation I’m struggling to the identify the individual problems, let alone the solution.
