[NTLUG:Discuss] Strange iptables problem on CentOS 4.4

[. Daniel]

That's an interesting question.  I had seen something like that not too 
long ago.  It too was CentOS 4.4 in fact.  I think when I saw the error, I 
hadn't yes corrected a router configuration mistake I had made.  I was 
attempting to forward all data for a given IP address to a specific machine 
within the firewall.  What I failed to do was make the machines responses 
MASQ through the same IP address.  Once I made the Masq correction, it 
worked just fine.

My first impression was that "hey, this must be the 'secure' part of ssh."  
I still don't understand why ssh is better than telnet... other than the 
plain text thing, but then again, who will be sniffing in average 
situations?
