Hi,
this is one of those questions asking if FreeBSD is able to do it or not.
I have two ethernet cards with IP numbers configured on the same subnet e.g.
# ifconfig -a
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.108.132 netmask 0xffffffe0 broadcast 192.168.108.159
ether 00:40:95:96:0c:c3
ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.108.151 netmask 0xffffffe0 broadcast 192.168.108.159
ether 00:a0:24:10:e5:b4
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
ed0 and ep0 are the two interfaces. Now I want to add a static route to host
10.1.2.3
via interface ep0. All other traffic has to use ed0. The default gateway which
is also the
gateway to 10.1.2.3 is 192.168.108.158.
I tried something like
route add -interface ep0 -host 10.1.2.3 192.168.108.158
and it results in
route: bad address: ep0.
Is it possible to achieve the routing I want? Do I have a syntax problem with
route?
The machine does not do ipforwarding and firewalling, routed and gated are NOT
running
but I could install/activate those if needed to achieve the routing. OS version
is 2.2.7.
I know that I could put the second card onto another subnet and it will work
just adding
a route to the gateway of that subnet.
The reason for this kind a tricky thing is to account the traffic to and from
host 10.1.2.3
on the switch connected to the FreeBSD machine (it is one of the central
accounting
machines).
Thanks in advance,
Marcus Haebler
