Hello,

    I've got a NetBSD-1.2-sparc system setup call my ISP over PPP.
    Everything is working, however, I've added a second machine to 
    my network and I can't get it to connect outside. It appears
    that the datagrams are getting routed out over the PPP line, but
    not making it back. I've checked routed, and its being called
    with -s (I tried -g as well). I'm using a kernel with option 
    GATEWAY set as well.

     Sparc is 192.1.1.3 and my other machine is 192.1.1.7. The basic
     PPP script I'm using is, nothing set in /etc/ppp/options:

     /usr/sbin/pppd \
     connect '/usr/sbin/chat -v -f /home/nomad/bin/udPPP' \
     /dev/ttya \
     38400 \
     -detach \
     debug \
     crtscts \
     mru 1500 \
     mtu 1500 \
     bsdcomp 15,15 \
     modem \
     defaultroute \
     netmask 255.255.255.0 \
     lock \
     noipdefault

     I removed proxyarp since it gave an error:
     pppd[855]: Cannot determine ethernet address for proxy ARP

     It appears as though routed is trying to communicate with the PPP 
     server to update its routing tables, but of course that host isn't
     running routed.

     So, I suppose that I need to tunnel these packets from the sparc
     somehow? I see the modem's lights blink send, but not recieve.

     I'm a newby with BSD, what are my options? Or more specifly, how 
     do I setup my Sparc to act as my gateway? Should I be using gated
     instead? If so, could someone post a sample configuration?

     Any help or suggestions is greatly appreciated.

                                    Thanks in advance,
                                    Joe Rach
