Routers with inbuilt DynDNS clients
This list is probally far from complete. Please post in this forum if you find out that your router has an inbuilt DynDNS client and is not listed.
Please read your routers manual to find out how to configure the client. All you will need to enter is your DynDNS.org username and password, and the hostname that you chose.
