Hi,
 Sorry that I hit the Send before I finish it.

 I have a question about iptables in fc5. I have iptables 1.3.5-1.2 installed.
 By default, the iptables has a line
 -A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
 ... and
 -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

 I try to add the port 2049 for our lan nfs by adding aline before the above
 reject line:

-A RH-Firewall-1-INPUT -s 128.252.85.0/255.255.255.0 -m state --state NEW -m
tcp -p tcp --dport 2049 -j ACCEPT


That rule will only match the initial packet of the stream.  You will
also need to match states ESTABLISHED and RELATED:

-A RH-Firewall-1-INPUT -s 128.252.85.0/255.255.255.0 -m state --state
NEW,ESTABLISHED,RELATED -p tcp --dport 2049 -j ACCEPT


-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

and restart iptables.  But my other linux boxes cannot mount the exported
folder.  If I stop the iptable, then they can mount it.  I tried to open
several other ports: 137, 139, etc.  But as long as the last line is there, it
always failed.  If I comment out the last line, then nfs works.

What is "icmp-host-prohibited"?  How to set it to allow some requests?  It
seems that it is different from in fc4. Is there any link for iptables in fc5
where I can learn more?

Thanks!
