Dietmar, may I ask a few questions? I plan to use dyndns with my server, through a dialup connection, so some of my friends and I can play a MUD on one of my boxen. I want to port-foward the appropriate port to the correct box on my home network.
Jim,
ok, you have your sme-box as server and gateway and would like to have a domain with dyndns on a second box. And you have a dyndns-domain.
So, you should go to these steps:
1. Create an i-bay on your sme server and gateway with public access to the internet (no pw required).
2. Finding the register domains in the section configuration, add a new virtual domain based on your new i-bay, where the domainname must be a FQDN (full qualified domain name, f.e test.homelinux.net). The content should show your i-bay.
3. Depending on the appropriate port, you can forward it to the ip-address of your second box. Therefore you should use the register port-forwarding in the section security.
4. Last but not least you would like to have an automatic ip-update for your dyndns-domain at every dial-in. Now it's time to use the ddclient-option.
Clicking on the ddclient-contrib, you can see the current list of virtual domains with the new one in it. With "Create" you should configure your client (f.e dyndns.org dynamic addresses), user, password and mx-record (this should be the same name like your domain).
Rgds.
Dietmar
