Ah thats fairly easy to configure...
Just set the Speedtouch up in standard nat mode.
Then go into the CLI..to do this open a command prompt and type: Telnet 192.168.1.254 (assuming that is your router's IP address) and press enter
Type Administrator as the username (thats the default - note the capital A) and press enter
When prompted for the password just leave the field empty and press enter again, unless you have changed the password.
Now... (with a.b.c.d as your external/public additional IP, and p.q.r.s as you internal/client computer IP) type the command :
nat mapadd type=nat intf=Internet outside_addr=a.b.c.d inside_addr=p.q.r.s
You can confirm what is setup with the command:
nat maplist
And you can remove a previously set up static NAT with the command:
nat mapdelete intf=Internet index=?
index can be determined from the nat maplist command
when you are done in the CLI don't forget to type the command:
saveall
..as unlike the web interface changes are not automatically saved (so you need the saveall command if you want them to survive a reboot)
You can quit the interface with the command:
exit
Note these commands are case sensitive. If you are unsure on the CLI commands you can start typing and press tab to complete, or you can type ? and enter for help (or a command followed by ? for help on that specific command)
Kindest regards,
