Hi,
I have a problem with ipfw:
(10.0.0.x) (ed0)(10.0.0.1)(rl0) (1.2.3.4)
--LAN----------------FreeBSD--------------ISP_1
|
|(rl1)
|
| (5.6.7.8)
|_________________ISP_2
thw default route is 1.2.3.4
( $ route add -net 0.0.0.0 1.2.3.4 )
I want to forward only port 80 from LAN to ISP_2 .
I do:
$ natd -p 8668 -interface rl0
$ natd -p 8669 -interface rl1
$ ipfw add 500 fwd 5.6.7.8 tcp from 10.0.0.0/24 to any 80
$ ipfw add 1000 divert 8668 all from any to any rl0
$ ipfw add 2000 divert 8669 all from any to any rl1
and it's seems not to work .
'tcpdump' on rl1 show connections from 10.0.0.2.3122 > WEB_SERVER.80 , and
it must be: 5.6.7.8 > WEB_SERVER.80
is missing the natd .
what is wrong?
thanks.
