Ok, traceroute shows the next hop is:
1 tc3-1-hfc.stcla1.sfba.home.net (24.1.4.193) 16.235 ms 14.679 ms 14.715 ms
this corresponds to what I was told when they installed the cable modem. It supposedly
is my gateway address on the cable network.
So I should add a route like:
route add -net 24 -netmask 255.0.0.0 24.1.4.193
and for ftp.netbsd.org
route add -net ftp.netbsd.org 24.1.4.193
Which doesn't produce any tcpdump output on any interfaces when I ping.
route get 24.1.4.193 shows:
route to: tc3-1-hfc.stcla1.sfba.home.net
destination: tc3-1-hfc.stcla1.sfba.home.net
gateway: c528574-b.stcla1.sfba.home.com
interface: ne0
flags: <UP,GATEWAY,HOST,DONE,STATIC>
recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtu expire
0 0 0 0 0 0 0 0
ping 24.1.4.193 gets:
PING tc3-1-hfc.stcla1.sfba.home.net (24.1.4.193): 56 data bytes
ping: sendto: No route to host
ping: sendto: No route to host
I guess I'm just to network dumb to get this?
Thanks for you help,
Paul
