our internal domain has a different dns name, internalsite.org, than our external, externalsite.org. our website (hosted elsewhere) uses www.externalsite.org
, our email addresses use @externalsite.org
we have external dns entries set up for our web, mail and terminal servers, the external entries used to work from both on and off campus until we put in a new firewall today. now webserver.externalsite.org
works off campus, but not on! same for mail and ts.
the firewall folks (watchguard) say we need to reconfigure our setup and put our mail and webservers into a dmz. I'd rather not do that considering the time and work it would require. any thoughts? how much would it require to change the fqdn of our internal dns scheme?
any thoughts or help is much appreciated.
