setsockopt failed: Protocol not available
|
Dear All:
I had compiled my kernel over. but i still have some question with NAT .
--------------------------->>>
why not i type ipnatadm -O -i -P tcp -S 192.168.200.17/32 -M 206.229.31.17/32 -W eth0 would happen error ,here is error message below:
ipnatadm:setsockopt failed : Protocol not available
What happen in my Linux ? I also draw my network frame's picture for all and what i hope to finish ?
----------------------------->>>
192.168.200.17
webserver---| 192.168.200.253 206.229.31.253
11 | eth1 eth0
bill--------|-------|| Linux Box||------||Router||---Internt
10 | 206.229.31.254
pason-------|
18 |
ftpserver---|
19 |
mailserver--|
I hope NAT can finish below function:
F1. => I had to configure WWW(192.168.200.17),FTP
(192.168.200.18),Mailserver(192.168.200.19)
in private network [192.168.200.0] ; so such as if you want to access my www-services ,you
type 192.168.200.17 in Netscape-Browser , you would direct access my private network's
Web-server box ,because 206.229.31.17 not have a physical box, so my Linux-NAT must
translate 206.229.31.17 with 192.168.200.17 ,so did you know this software can do it ,if it
can do it ,did thay can finish another services such as FTP AND Mail?
F2. => can i limit some box's ip to access internet's services,such as i allow bill to access mail but not
not allow he access www and ftp.so can i limit their port in linux-NAT
can you advise me with your opinion? thank you in advance . Tsai David Regard.
