Forward All Ports

Forward all Ports to One IP Address

Thomson TG585v7 & TG587n Routers

If you need help with telnet commands, see this first telnet.html

Objective
To forward all ports to one specified IP address on the LAN or DMZ network.
Useful for a web server or to fix a strict NAT's issue with a games console.
In this example I've chosen to forward ports to IP 192.168.1.50.
The PC or games machine needs to be placed on this static LAN IP.
If a different IP is required choose one from outside the DHCP pool.
With the default configuration this means using a IP in the range 192.168.1.1 to 192.168.1.63

This method removes all protection offered by the routers firewall.
Ensure you are satisfied with the security aspect.
Do not be tempted to forward a range of IP addresses, this will break the DHCP.
Also "unassign" any existing port forwarding rule before trying this.
If you have any issues then a factory reset will return the router to default settings.

Commands

Command	Comments
nat tmpladd intf=Internet type=nat outside_addr=0.0.0.1 inside_addr=192.168.1.50	See note (1) below regarding "intf=Internet"
firewall rule add chain=forward_host_service index=1 name=AllPorts srcintf=wan dstip=192.168.1.50 state=enabled action=accept	Open firewall to IP 192.168.1.50
firewall rule list	Optional -- view the firewall rule
saveall

Now place the device (PC or Games machine) on a static LAN IP of 192.168.1.50
This is how the settings would look in a windows PC.

Don't forget you will need to allow the necessary ports through any software firewall / windows firewall on the target PC.

Undo Commands

First use the command firewall rule list

Note the firewall index number for the rule AllPorts. In this case the firewall index number is "1".

Also use the command nat tmpllist

Note the NAT index number for this port forward. In this case the NAT index number is 15

Commands	Comments
firewall rule list	Use to find the firewall index number -- see above
firewall rule delete chain=forward_host_service index=1	Use the index number found above.
nat tmpllist	Use to find the NAT index number -- see above
nat tmpldelete index=15	Take care to use the correct index number.
saveall

Note (1) :
The "intf=Internet" part of the above commands may need to be changed depending on the routers firmware.
ie "intf=Internet" should be correct for standard firmware.
O2 supplied routers may need "intf=Internet" replacing with :-
For O2 supplied routers on a LLU connections replace with "intf=O2_ADSL2plus" or in some cases "intf=RoutedEthoA"
For O2 supplied routers on the Access service replace with "intf=O2_ADSL"
Hint - You can check which one to use for the WAN interface by looking at the results from the "dns server route list" command.
See the screen capture below, in this case it's "intf=O2_ADSL2plus".
