Hello!
I'm new to FreeBSD (5.3) and trying to make the transition from Linux. One
thing that has me stumped is a routing question... it must be something
really simple because I can do it all the time in Linux.
I just want to add an arbitrary machine (eg. with IP 192.168.2.214) to my
home network 192.168.254.0/24. Under Linux I just do a
route add -host 192.168.2.214 eth0
and I can ping it.
On FreeBSD I tried both
route add -host 192.168.2.214 192.168.254.245
route add -host 192.168.2.214 -interface rl0
but I'm getting some kind of redirect loop. Apparently my use of the
FreeBSD route command is wrong.
BTW - I don't want to use DHCP for various reasons (mainly because I need
to ssh to the new machine and therefore need to have a known IP address -
but also because some of the machines I need to add don't support DHCP
clients or else setting them up to do so is just too much).
I haven't got round to natd and firewalling stuff yet and I won't try
turning these on until I can at least ping the new box. For now, these
features are not enabled in /etc/rc.conf.
Just to eliminate the obvious - yes I booted Linux on this machine
and tested it and it worked - so it's not a h/w problem.
Here's the detail: I'm issuing the "route add" commands on "raita" and
trying to reach "rasam":

I tried two ways to add the route to rasam from raita:
1/ using the address for the interface:
# netstat -rn
