Hi,
I'm trying to get my FreeBSD 3.3 box up and running as a gateway between
2 local subnets. I have already recompile the kernel with the IPFIREWALL,
IPFIREWALL_FORWARD, IPFILTER, DUMMYNET, and BRIDGE options.
Currently the firewall rule is allow all from any to any.
subnet1 -- gw -- subnet2
Here's what I've got at the console when I type netstat -r:
localhost localhost UH 0 1 lo0
192.168.1/26 link#3 UC 0 0 ep0
gw <gw ep0 ether addr> UHLW 0 2 lo0
192.168.1.5 <host1 ether addr> UHLW 1 1550 ep0 694
192.168.2/26 link#1 UC 0 0 xl0
gw <gw xl0 ether addr> UHLW 0 136 lo0
192.168.2.63 ff:ff:ff:ff:ff:ff UHLWb 1 1 xl0
But I encountered a problem, when I ping from gw box to host1 box,
I always have the responses back to me in about 10 to 40 seconds.
Then in the host1 machine, I type "tcpdump -i ep0" at the console
and I think host1 runs correctly, because it always reply immediately
after it gets the echo request.
When I unplugged my xl0 device out of the machine, everything goes well.
Anyone, please help me fix this problem.
Thank you
Benedict
