I seem to have an irresolvable problem, but I'm sure I'm just 
misunderstanding something.

I have the following active network configuration in a NetBSD-1.3.3-i386
system:

# netstat -in

and I'm trying to add a default route via ne1, the gateway being 
192.168.30.17.

# route add default 192.168.30.17

The result is disappointing: 

Internet:

default            192.168.30.17      UGS         0        0      -  ppp0
                                                                     ^^^^

I tried:

# route add -ifp ne1 default 192.168.30.17

but route(8) seems to expect something else after -ifp, it seems to try 
to resolve the "ne1".

Before I return to that, I tried -ifp 0 and -ifp 1, assuming that 
perhaps an index was required, but I got no results.  -ifa would seem 
to need an address, but 192.168.30.22 is assigned to both ne1 and ppp0, 
so it would not seem to act as a selector at all.

So, I looked at route(8)'s sources.  Can't quite figure out from the 
available information, not even after looking at /usr/include/netinet/
in_var.h what I'm supposed to understand IFP to mean.

Help, anyone?  Perhaps some indication where to look?  I have copies of 
TCP/IP Illustrated, if I should look there, but I honestly don't know 
where to start looking.

And while I'm asking, where could I find the updated traceroute(8) that 
automatically selects the most sensible interface rather than the first 
one?

PS: seems I'm having trouble resubscribing to tech-net, so if you see 
this you might have to reply off the list to get to me :-(
