I have two answers:
1/ Use ipfw add NNN fwd localhost,8001 [deny criteria]
to make the packet that is denied go to a default server listenning on
port 8001
2/ there is an in-kernel webserver built using netgraph but it&#x
Same thing, it only works for telneting to test2:80 for test1.

Hi, Julian:
Here's all the rules that I am using:
[17:13:59][root@test2:~]$ ipfw show
001000 0 allow ip from any to any via lo0
002000 0 deny ip from any to 127.0.0.0/8
003000 0 deny ip from 127.0.0.0/8 to any
004000 0 allow udp from 0.0.0.0 2054 to 0.0.0.0
00500

My goal is using test2 as authentication server, when http request pass
through test2 box, test2 will redirect to an authentication url on itself.

You cannot do a socket directly but you can indirectly
tell me what you are trying to do and I can help..

I am trying to modify ip_fw.c in the /usr/src/sys/netinet, I tried to add a
socket call in the code, it can be compiled, but when it runs into the code,

wrong.
Can any one tell me if socket call can be used in kernel level?
