I have the need to send sms messages from the wan side of a raven xe modem. I have a server in the cloud, a raven xe that I am connecting to thru a MVNO via vpn(private static). I am able to send sms when I telnet in using the local lan port, but cant get it to send when trying to send thru the wan IP using telnet. Is there a restriction on sending via the wan port? or am I missing a setting somewhere?
Here is the command I am using, which works on the local lan port using the ip address 192.168.13.31 and telnet, but not when telnet to the wan IP:
