You have not used MASQUERADE in your POSTROUTING rules or haven't showed
it..

iptables -A POSTROUTING -t nat -p tcp -s 192.168.0.42 -d
207.106.22.35 --dport 80 -j MASQUERADE
iptables -A POSTROUTING -t nat -p tcp -s 192.168.0.23 -d
207.106.22.35 --dport 80 -j MASQUERADE


without the rules above, the 192.168.0.XX packets leave the network out into
the internet and eventually get dropped by some ISP...

Subject: SMTP HTTP port allow


I am implimenting iptables for first time.
I want to allow all my LAN users to send emails to SMTP (port no. 25) all
destination with following code. :

***
iptables -A FORWARD -p tcp --dport 25 -j ACCEPT

***

I also want to allow LAN users having ip 192.168.0.42 192.168.0.23 to upload
contents to webserver on ip 207.106.22.35 (outside of LAN) with following
code.

***
iptables -A FORWARD -p tcp -s 192.168.0.42 192.168.0.23 -d
207.106.22.35 --dport 80 -j ACCEPT
***

I would loke know whether It works or not.
Tell me whether my code is O.K. also where can i check logs.
Thanks
