I've configured my freebsd 2.1.0 as a gateway from my lan to my ISP.
I recompiled the kernel including the IPFIREWALL and IPACCT options and
I tried to account the packets that are passed into my lan and sent out
through SLIP by using the commands:
ipfw adda single all from any to my.net.address.0 on sl0
ipfw adda single all from my.net.address.0 to any on sl0
and using the following command to print the accounting.
ipfw -as l a
I found that the accounting was incorrect. It accounted all packets
regardless of on sl0 or ed0 (ethernet). For example, when I telnet from
other machines in the same network to the freebsd (it's on ed0), the IP
accounting adds all packets as if it ignore the parameter "on sl0".
Could anyone give me a recommendation?
Thank you,
Ekasit K.
