okay.

I assume you are using pppoe, if i recall correctly,
you can grep the gateway address off the 'ifconfig <device>' output.

IPE/NME is supposed to be the external ip 1 and its netmask.
Since you are a single host, you can skip the NM part.
if you don't want to skip, use either /255.255.255.255 the old way,
or /32 the new way. 

NWE is supposed to be you externernal IP-Range/Network, you don't have
one.
