Hacking autoexec.net on a P660-HW (Nat loopback)

The ZyXEL P660-HW router has a nice feature that allows you to turn on NAT loopback. I want this to always be on! The default is off on a reboot.

Enter "sys edit" a primitive editor living under Menu 24, submenu 8 of the telnet admin interface.

Log in, drop to a command shell and type

sys edit autoexec.net

Keep hitting N(ext) until you see "EOF" appear. You've found the line to insert after.

Q(uit) and then type "sys edit autoexec.net" again. This time hit N until you see the line before EOF appear. On mine this is something to with adsl dmt2. Then type I(nsert), followed by "ip nat loopback on", then X(it) edit.

To remove, just hit D(elete) when the "ip nat loopback on" line appears, then hit X(it).

Techy, yes, geeky, yes, irritating to find, yes, useful feature, yes.

Take that you ZyXEL P660-HW!
