Hi,
I'm running 2.2.8-RELEASE, and I noticed, that static host routes to
directly connected hosts don't seem to work correctly. I have the
following Problem:
192.168.25.0/24 ------ed1 |FreeBSD| de0-------- 172.27.0.0/16
|
---- Host 192.168.25.224
where the addresses of the interfaces of the BSD-Box are:
ed1: 192.168.25.223
de0: 172.27.10.254
For the single host I need a hostroute to de0, and i thourght, this line
should do the job:
# route add -host 192.168.25.224 -interface 172.27.10.254
After that the routingtable looks fine so far:
192.168.25.224 172.27.10.254 UHS 0 0 de0
but it doesn't work, no arp-requests for 192.168.25.224 on de0.
Because i was not sure, if it is a netmask-problem, I tried the same with
an address out of 172.27.0.0/16, for example 172.27.1.1, which was routed
correctly before, and from this moment on the address was unreachable. It
seems that static host routes don't route but block, and no arp-requests
happen anymore for that address.
Then i tried the -interface-option with the real device-name:
# route add -host 192.168.25.224 -interface de0
and it created a permanent arp-entry, but with the ether-address of the
adapter of de0, again no arp-request was done. With arp -s I manually set
the ether-address to that of the host, and, WOW, it works! But this can't
be the way to do it, can it? I would like to have a solution, where I
don't have to set the ether-address by hand but it is determined by an
arp-request.
Btw.: if I route a whole subnet (at least 2 IPs), there's no problem
anymore, fine arp-requests, fine connects.
I'm really confused, and from my point of view this is a bug, but maybe
someone can explain me, what I'm doing wrong?
Thanks in advance,
Sven
