Here is my scenario and would like your inputs on the same. I have setup PepLink Balance with Subdomain delegation and have setup rdc.example.com A record for ISP1 [220.127.116.11] and ISP2 [18.104.22.168] giving ISP1 a high priority.
This FQDN rdc.example.com is being used by users to take RDP of internal server which is natted with 172.16.1.10. Now if users are connected with rdc.example.com [22.214.171.124] and if that link goes down will it be automatically transferred to rdc.example.com [126.96.36.199] or that connections will be broken and next time when user connects it will be routed to rdc.example.com [188.8.131.52]? Same with other protocols? Like SSH or ftp?
