This is because I want the external users to see the internal machines(172.16.4.0 network) as it is. Does your gateway have the address you want attached to it? At a command prompt, type "ip addr" If the output does not include a line that starts like: inet 172.16.3.10 Then it can't and won't forward out that way. If not, add this line to your rc.local file: ip addr add 172.16.3.10 dev eth1 And, while you're at it, run it, as root, from your command line, to add that IP address to your external interface. -- Mike Burger http://www.bubbanfriends.org Visit the Dog Pound II BBS telnet://dogpound2.citadel.org or http://dogpound2.citadel.org To be notified of updates to the web site, visit http://www.bubbanfriends.org/mailman/listinfo/site-update, or send a message to: site-update-request@xxxxxxxxxxxxxxxxx with a message of: subscribe -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
