Modem: Thomson tgt585v7
Requirements:
1-Ps3
2-Pc connected to the modem
and the most important one is you need to insert a custom ip address in the ps3 (for ex **192.168.1.68**)
Choose an ip which is not taken/used by a device in your household
The config of the ps3 should be :
Ip Address : **192.168.1.68** ( for example )
Subnet Mask : 255.255.255.0
Default router 192.168.1.254
Primay Dns : 192.168.1.254
Secondary Dns : 0.0.0.0
MTU : Auto
Upnp : Disabled
Keep in mind this is for ps3 connected via ethernet i don't know if this works on wifi connected ps3 machines
The pc part
You'll need to enable telnet which can be enabled if you go to the address in explorer
Control Panel\Programs And select "Turn Windows features on or off" and search for "Telnet Client" And enable it.
Now after it is installed "takes a couple of minutes for that" Press windows key + r (just to open run in style)
and type telnet 192.168.1.254 ; Default Username is Administrator with a blank password
Now enter the following commands :
1-nat tmpladd intf=Internet type=nat outside_addr=0.0.0.1 inside_addr=192.168.1.68
2-firewall rule add chain=forward_host_service index=1 name=AllPorts srcintf=wan dstip=192.168.1.68 state=enabled action=accept
3-ids config state=disabled
4-saveall
5-exit
_____________________________________
Notes : The ip address can be anything you want but if you want select 192.168.1.68
If the Username and password didn't work you'll need to contact your isp
Go to
http://192.168.1.254/cgi/b/games/cfg/?be=0&l0=2&l1=4 in your browser and uncheck upnp
This is meant to work if your ping is in a good state and you can be able to connect to game servers
