Dynamic DNS via changeip.com

I am trying to create a VPN tunnel via T-Mobile, and is does not get through them with noip.com…If I use the 440GX as strictly a modem, and put a Sonicwall TZ170 on the inside, Changeip works fine identifying the IP and forwards without issue and without interference from T-Mobile. Is there a way to use changeip.com for my GX440?

Any help would be appreciated.

from this it seems Changeip is working fine at your end :confused:

thanks,
Rex

I was hoping to not use the Sonicwall appliance for my VPN tunnel though.
