Hello List, I have a Problem with NAT on RedHat 7.3/iptables v1.2.5.
I have 2 Hosts. I want to redirect every connection to Port 3306 on Host1 to Port 3306 on Host2. That is no problem as long I make an external connection (Prerouting). I also need to redirect connections to localhost:3306. According to the Howto's I need to set this in the OUTPUT chain. So I use exactly the syntax from the HOWTO's: iptables -A OUTPUT -t nat -p tcp --dport 3306 -j DNAT --to 10.1.0.212:3306 iptables reports: "Invalid Argument" I've allready played arround using -i lo, etc. The same errors. It simply seems as if DNAT on OUTPUT isn't possible, but the HOWTO's say it is. I also read, that OUTPUT DNAT was a Problem in 2001, but that's long ago I think. Please help! Thanks in advance Daniel Khan
