I would look at it this way: Login via SSH to one of the boxes from which you cannot access the other box. Then check what works: HTTP connection: lynx http://<IP-of-other-box>/ HTTPS connection: lynx https://<IP-of-other-box>:443/ SMTP: telnet <IP-of-other-box> 25 POP3: telnet <IP-of-other-box> 110 SSH: ssh -vvv <IP-of-other-box> See what error messages or additional information you get. The "-vvv" in SSH makes the output more verbose and might give some additional pointers. For the other connections: See if you get "connection refused" or timeouts, because these point to different underlying causes of the problem. Another thing: If you're using NAT and the servers are in the same subnet, then it could be that you have a NAT problem. Like that the connection between DMZ servers goes as far as the router, but a configurational directive prevents it from going further. -- With best regards Michael Stauber _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
