Connecting GPRS with EDGE

[louisp]

Hi,

I'm trying to connect 2 PC's. One is a Laptop with an Edge card, the other is a PC with a cable connect to gprs phone.

Both PC's can ping sites and even other PC's. but I can't get them to ping each other.

Firewalls are off.

It seems that MTN is dropping the packets on the third hop.

Any Advice??


Tracing route to 172.24.30.*** over a maximum of 30 hops

AFIK the MTN network uses NAT (Network Address Translation).

That means that all MTN users have the same IP address outside the MTN network. NAT sorted out where incoming trafffic should be routed to inside the MTN network.

The bottom line is that you cannot ping a PC on the MTN 3G/EDGE/GPRS network.

For more information about NAT see:

That would make sense.

I thought it was some internal firewall/proxy blocking the ping requests. It could be true, allthough it didn't appear to be as both PC's reported different IP's.

Is no one on EDGE then able to setup home web pages, alarm systems, remote desktop, etc?

You need an internetvpn apn AFAIK. Call them and ask for one. Haven't used it myself though.
