SBS 2003 Comcast SMC Modem unable to access FQDN internally
Posted on 2011-10-13
I have an SBS 2003 server connected to a Comcast Business Class modem using the modem as a router. I have a domain record for our domain that points to our Static IP, mail.domain.com. From the outside I can go to a computer and type mail.domain.com and have access to OWA for exchange. When inside the network the firewall will not forward mail.domain.com address to the server. I'm guessing this has to do with the firewall but am not sure. Any ideas?
Other sites that i manage i use a Sonciwall for the firewall. The firewall rule allows you to forward port 80 requests from the LAN and the wan but It seems the SMC gateway doesn't allow this.
