hello guys!!! Can someone help me on my problem regarding iptables??? This has been my problem a month now.. I'm running a redhat 7.3 firewall server with two NICs; eth0 facing the internal network (192.168.0.x) and eth1 facing the internet (external network). Now I wish to forward all traffic on eth1, port 25 to another to my mail server (say, 192.168.0.2). I did something like:
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE iptables -A FORWARD -p tcp --dport 25 -d 192.168.0.2 -j ACCEPT iptables -A PREROUTING -t nat -p tcp --dport 25 -d x.x.x.x -j DNAT --to 192.168.0.2 Now when i used to test SMTP connection thru telnetting from another server... say: #telnet xxx.xxx.xxx.xxx 25 It just stucked in there doesn't continue... using nmap on my firewall: #nmap xxx.xxx.xxx.xxx -p 25 it says that port 25 is filtered... Is there anything wrong with my iptable rules? I would really appreciate if you can send me your help... thanks! Oliver __________________________________________________ Do you Yahoo!? Yahoo!
