We are an IT company that implement Exchange 2010 (usually SBS 2011) and provide internet acess.
Due to living in South Africa we are forced to cater for 3g ADSL failover and dynamic IP addresses as a result.
We are having a problem using dynamic IP addresses with outlook anywhere.
When it is a static address we point the A record remote.domain.com to the IP address for the domain and things work great.
When however using a dynamic address we can't find a workable solution.
If we update the A record to point to domain.dyndns.org it resolves domain.dyndns.org to its current IP and sets that in the A record. Therefore when the IP address changes it does not update.
I have also tried changing the outlook anywhere connect from https://remote.domain.com to https://domain.dyndns.org but get certificate erros.
I have tried adding a self cert (SBS 2011) for domain.dyndns.org but that changes the email addresses for the users!
Any assistance, suggestions or directions would be most appreciated
Thanks
