external.if file sets the name of the external interface.
I believe it should be local.arp, and on a NT system it should be in
%SystemRoot%\fw\state\
With the IP address of the Natted box then TAB the mac address in this
format xx-xx-xx-xx-xx-xx
Then reinstall the rule base. It is important to create this file using
edit.com

I believe it is the external.if file in the $FWDIR/conf directory.
