RDP to home network no longer working

[marcus2704]

Ive spent ages trying to resolve this, so will be very grateful for anyone who comes up with the answer!

I have a D-Link DIR615D2 provided by Virgin Media. Until recently, I was able to come into my home network via RDP, however am no longer able to since the router appeared to reset itself.

I am fairly certain this isnt an internal network issue, rather one with the DLink, as I tried my old Lynksys router and was able to RDP to my internal network fine from external internet.

I have set up a TCP port forward condition which sends requests on port 3389 through to my internal client 192.168.1.102, which has a fixed IP. Clientside, port 3389 is open, and listening. Internally, I can RDP fine to that client, which is joined to my Windows 2008 domain.



I have been using the standard V1.00 factory firmware since I had the router, but today tried a DD_WRT firmware with no success. I have tried a multitude of things, down to removing and reseating the coax from the cable modem, enabling ICMPv4 so my W7 client is pingable from the router (which it is). Whether I try coming in through the internet IP directly, or through my DYNDNS service it still fails to connect.

The internet IP from the working router is different to that of the DLink, which I presume is down to the IP Lease renewing itself against the new routers MAC, however I did call VM and ask them to change my IP for a last ditch effort in getting this working! (they said they would, but so far its still the same..).

Short of buying a new router, which seems unneccessary really, can anyone think of anything else I can try?

My first port of call would be to wireshark both ends of the connection to see what is happening at the network TCP/IP layers.

The IP address in the pic is .102 - you say your client PC is .100? Or am I missing something here?

So sorry, my mistake, the IP is 102 not 100. Ill fix the original post.
