No the Zoom 3x has a DMZ section I believe. You have to enter 10.0.0.2 in a web browser to access the interface and configure the DMZ for your modem. I guess you have to DMZ your router that should be the 192.168.1.1 . That means go in a browser enter 10.0.0.2 enter the default password or whatever (see the instruction manual that came with it). Find the DMZ section of your modem and enter the IP 192.168.1.1 (should open your router to all possible traffic). Again what I say might be different from what you'll encounter. I have to say that the Zoom modem with routing properties seems overkill and might stopped you from connecting to the gnet fully. You do the tests. You decide.

Ciao et bonne chance

OK - I had set up to have my laptop in the DMZ (192.168.1.102) but I have now put the Linksys Router (192.168.1.1) instead... but still no joy though !

The above address is the manual of your modem. It made things a little clearer in my mind. First, the modem gives a IP to the router like 10.0.0.3 (you'll have to check the DHCP table to know the address used it is between 10.0.0.3-10.0.0.15). Once you found that IP, you'll have to enter it in the DMZ of the modem. That way all ports will be forwarded freely to your router. After that you just do the normal portforwarding config in the router as explained above (forward port 6346 to 192.168.1.102) and the forced ip in LW.

Bonne chance!

Sounds promising - will have a try tomorrow and let you know if it works.

Thanks for your help

Still no joy I'm afraid - I've added the modem's IP address to the DMZ.

Should I have the port forwarding direct to my machine (thats what it does at the moment)or should I forward to the Linksyss router and at the Linksys then forward the port on to the computer ?

It is the router IP given by the modem that you have to enter into the modem DMZ. Do not forward Linksys IP.

The IP address I have put into the DMZ of the Zoom modem is the DHCP client address shown on the web console (10.0.0.10)

I had port forwarding set up on the modem to forward port 6346 to my laptop (192.168.1.102), and also have port forwarding on the LinkSys forwaring the same port on to the laptop as well.

That didnt work so my question then was should the port forwarding on the modem be forwarding the port directly to the laptop, or on to the IP address of the linksys (192.168.1.1) which in turn should then forward on to my laptop.

Either way still doesnt work.
