Double NAT or other communication problem

Tuning in

Hey,

I have been having troubles with my internet, what began as a seemingly intermittent and slow connection, eventually turned into complete inability for services to communicate with my networ.

I usually have a set up where my own router is hardwired into the SH4 in modem mode, and then my PC is hardwired into the router..
I have also tried using the PCC directly hardwired to the SH4 in both modem mode and in router mode.

When running a trace route in each of the possible set ups, I am faced with the same outcome..

a) SH4 Modem Mode > Router > PC:

Tracing route to virginmedia.com [213.105.9.24]
over a maximum of 30 hops:

1 1 ms <1 ms <1 ms 192.168.1.1

Trace complete.

...a technical support member of Ubisoft and elsewhere have told me that from the trace route it appears to be a Double NAT, whether it is or not, the outcome is the same as if it were... Services are unable to communicate with my network and vice versa, causing some things to entirely be unreachable, and others to intermittently disconnect due to a timeout..


I have no idea of anythiong else I can attempt myself, and telephone support at Virgin have been utterly useless and left me waiting for longer than they should have for a call back from somebody who would have the ability to help fix this..

A Trace dose not show if you are Double NAT 10. has always been their in some cases VM router their end shows the WAN gateway IP and in other cases 10. is missing with a timeout. You can tell if your Double NAT by checking your router IP that is the one your PC is connected too in WAN settings then go to whats my IP and see if is matches.
