Hi,
I am new to FreeBSD and router setup.
I have two ethernet cards for the router machine and they are configure
as follows:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 202.14.153.187 netmask 0xffffff00 broadcast 202.14.153.255
ether 00:90:27:06:3d:88
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 202.14.154.187 netmask 0xffffff00 broadcast 202.14.154.255
ether 00:60:97:b8:cf:70
The card, fxp0, is connected to Machine A with IP address,
202.14.153.190 through a hub and
the card, xl0, is connected to Machine B with IP address, 202.14.154.186
through another hub. There
is no problem in communication between router and Machine A and router
and Machine
B. However, when I tried to ping Machine A from Machine B and vice
versa, it fails to
connect. The IP forwarding is enabled by setting the gateway_enable =
yes.
The routing table obtained using netstat in the router is:

May I know what is the problem with my router configuration? How can I
configure the
router for Machine A to be able to talk to Machine B without changing
the physical connection?
Hope to hear from you soon.
Thank you in advance.
