Noah, That command should work, as long as the "$PORTFWIP:10700" is on the same line as everything else. Try executing it outside the script: #iptables -A PREROUTING -t nat -p tcp -d 10.0.0.1 --dport 10700 -j DNAT --to 10.1.1.1:10700 Of course, just replace 10.0.0.1 and 10.1.1.1 with your correct ips. If you get a command line, and no errors, (check the status with "service iptables status") then there may be something odd in the script. There may be a carriage return in the line somewhere, or one of the variables may not have a value. You can always duplicate the line in the script just before it executes for debugging purposes as such: --add to script before PORTFWIP line-- echo This should be executed next: "$IPTABLES -A PREROUTING -t nat -p tcp -d $EXTIP --dport 10700 -j DNAT --to $PORTFWIP:10700" --add to script before PORTFWIP line-- You should see the text followed by the actual line to be executed, with the variable's values. If any of the variables are empty, start troubleshooting it from there. -- Regards, Vinny Valdez -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
