Thanks, but unfortunately I can't, since some services must be able
to answer on both addresses.
the answer is to use the ipfw setfib rule for incoming packets on
the second interface.
setfib 1 ip from any to any in recv em0
In new freebsd kernels you can do this with ifconfig em0 fib 1 (I
think that's the syntax) without involving ipfw.
then the session will inherit that fib. Outgoing packets from that
session will use fib 1 while other outgoing packets will use fib0.
from the ifconfig man page. (FreeBSD 11 but I think it's in 10 too.)
fib fib_number
Specify interface FIB. A FIB fib_number is assigned to all
frames or packets received on that interface. The FIB
is not
inherited, e.g., vlans or other sub-interfaces will use the
default FIB (0) irrespective of the parent interface's
FIB. The
kernel needs to be tuned to support more than the
default FIB
using the ROUTETABLES kernel configuration option, or the
net.fibs tunable.
this can be simulated using ipfw setfib should you not have it in the
release you are running.
Maybe I could use socket in one fib to proxy to the other, but that
would probably make a mess in the logs when I have to identify who
connects to what and from where.
