RED: Support Backup Hostname for RED Connection
Currently, REDs and ASG must find and connect through the definition of a single host-name that is fully resolvable in the public. While this can use the DynDNS feature in ASG already for "fail over", it might be more simpler to just offer another host-name field to be used in the event RED looses connection to the main host-name?
Even with multiple WAN links avaialable to an ASG, the REDs use of just a single hostname poses a problem if that particular WAN link or ISP should drop for a time (e.g. fiber cut, dead modem, etc). The downed REDs wouldn't be able to connect in such a situation without some significant workarounds (e.g. DNS records modified to work with the other IPs and associated adjustment in TTL settings, ISP setting to redirect traffic, reconfiguring the host name on the ASG and on the corresponding REDs, etc.)
A backup secondary IP or hostname would be a nice enhancement that would help strengthen what appears to be a weak link in scenarios where remote office RED(s) rely on just a single ASG at the home office for internet access.
Such flexibility might also provide more flexibility to the ASG's automatic up-link balancing features as up-link balancing would likely already be configured and in use with multiple WANs present.
Second hostname is available with RED 50 and RED 15, we will not be adding this option to RED 10.
Created a new request thread to get this into the RED 10s. http://feature.astaro.com/forums/17359-utm-formerly-asg-feature-requests/suggestions/10996875-support-backup-hostname-for-red-10-connection
Though this is already being done by RED50's this would still be a GREAT addition to RED10's existing feature set.

While you work on this add it for sslvpn client aswell. So many customers have multiple internet connections, but can use only one for sslvpn.
Both ideas are build on the same idea, redundancy.
At the moment, we are using DNS Failover from a service provider, but it will be nice to have this feature into.
Agreed. Without expensive BGP supporting handoffs, a single hostname doesn't do any good when there is an uplink failure. waiting for dynamic dns to update is far too slow. Please add this feature.

This is a needed feature and would greatly help me having to manually changed the Hostname during an ISP outage. Please Add this feature.
