How to configure DynDNS for access with SSL

Posted on 2011-10-12

The goal is to correctly setup with a SSL certificate using a variable IP address in the office, so that the address remains the same when the IP address changes.

DynDNS endeavours to work around the issue with not having a fixed IP address ; however using their service does not seem to be straightforward to setup.

If the $30 a year standard service is subscribed to then the Nameservers have to be changed for the domain in order for the variable IP address issue to be resolved, as confirmed by technical support; however it would be preferable to keep the name servers as they are at the moment and simply add a DNS record with the exisitng provider.

using the free service you have the option to create which when configured with the current IP address ( and the router option to logon to the DynDNS account ), seems to partly solve the problem, as hopefully this address will continue to work even when the IP address changes.

However it would be better if a DNS CNAME record could be created via the domain providers control panel to link to; however I am not sure how to achieve this as remote. does not seem to be a valid subdomain, as the sub domain is already

How can link into DynDNS to display the SBS 2011 remote web workplace even if the IP address changes and does this have any bearing on the SSL certificate i.e. without an SSL certificate it is not possible to use the 'connect to computer' option on remote web workplace.

This seems to be a key reason to use a service such as DynDNS but I am not sure if it can fully substitute for a fixed IP address without moving the nameservers.

    This is an inherent design of DNS. To accomplish what you want you will need to use a service such as DynDNS and move name servers. There is no free workaround.

    Create a DNS CNAME record using the DNS control panel to point to (the DynDNS address does not need to have 'remote' in it anywhere).

    I have done this before and it wokrs but don't expect to be sending mail out on a dynamic IP address as it is normally blocked by most ISPs and other receiving email servers.

    Will having a dynamic IP address affect sending out email using the Internet providers smarthost? ( Incoming email will probably be configured via POP3 for simplicity ).

    That is entirely up to the service provider. You will need to check with their terms of use.
