Novice DNS and Exchange user here. I've got a lab for a mail server - MS Exchange 2010.
So here's the setup and scenario:
Server IP - 192.168.13.1 (DNS /AD/MS EXCHANGE 2010) ROUTER IP - 192.168.13.2
DYNDNS Personal domain - mydomain.com
x.x.x.x mydomain.com - A record (public IP address added in dyndns update client) x.x.x.x mail.mydomain.com - A record (same as above) 5 mail.mydomain.com - MX record pointed to mydomain.com www.mydomain.com - CNAME
MODEM ROUTER connected via ISP with FIBER PPOE Dynamic IP as usual.
- configured ddns service with my account
- configured with port forwarding PORTS for the http (80) and MAIL (25) to Server (192.168.13.1)
Exchange Server is working perfectly internally configuration is as follows
- host.mydomain.com - server name for physical and incoming and outgoing
DNS Server Records
192.168.13.1 mydomain.com - A record / NS Record 192.168.13.1 mail.mydomain.com - A record (same as above) 5 mail.mydomain.com - MX record pointed to mydomain.com
Besides the configuration for the dyndns I made above. How can I make this mail server work with externally. I have tried a lot configuration I got from a lot of forums but I can't seem to make it work.
What is the proper configuration and setup to make this external live access?
Any suggestions and recommendations are highly appreciated.
