Hi Wayne,

The local and public IP's on the interface are both different to that which
is displayed on the remote sites as my IP when I'm hitting them. The ppp
interface looks like this:

ppp0      Link encap:Point-to-Point Protocol
          inet addr:10.90.235.192  P-t-P:10.64.64.64  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:21 errors:0 dropped:0 overruns:0 frame:0
          TX packets:23 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:2498 (2.4 KiB)  TX bytes:1359 (1.3 KiB)

Hopefully the provider isn't nating the service, are you able to tell from
those details or will I need to contact them?

I've not made any modifications to the IP tables myself, this is a
completely clean voyage 0.6.0 build with just wvdial installed, I've not
made any changes to configurations outside of that.

Thanks mate,

Rob

Some of the 3g providers NAT your connection so inbound services will not
work

What is the IP on your ppp interface ?

Also do you have iptables blocking inbound ssh ?
