I have a webserver and few servers ( mail & file) which have ip addresses say 192.168.0.10 & 192.168.0.25 and are on the intranet. I can login to web server(apcahe) runnnig on Red Hat Linux 8.0 ( which has external ip address) thro' SSH from home and can even access mail . But when I connect to the mail server( sendmail), I am actually connected to the web server as the named.conf file on the web server has entry for mail server which is mapped to the ip address of web server. However, I cannot actually access the files on the mail server and same is the case with the file server. How can I establish connections to these mail and file servers?
Thanks for your support.
