I am attempting to use a Vodafone New Zealand network connected Android phone is establish a PPTP connection through to Telecom NZ TG585 modem to establish a connection to a PPTP server on a router.
I just can't seem to establish a connection and thought it best to check if anyone knows of or has used PPTP over said networks, especially the Thomson TG585v8
On the LAN based router (Linksys E4200 running Tomato firmware) I see the port 1723 IP packets, but they are dropped.
At this point I'm just looking for assurance that PPTP and GRE protocol can be routed between Vodafone NZ and Telecom NZ via a Thomson TG585 modem with PPTP passthrough (port forwarding) enabled.
If I test the connection on my local LAN it all works with no problems.
Just seem to be having a problem establish the connection via a WAN.
Thanks in advance for any help or thoughts.
