EXPERTS

I have two internet line and website at my company , I going to deploy peplink  link balancer at my company , If link A down Link B will take over for internet and inbound traffic,

for deployment Peplink need to modify External DNS record at ISP , Attached is example of NS record . My problem is unable to add ns record as hostname only allow to add ip address.

Anyone have experience with configure link balancer for webserver ?

Your ISP should be able to add reverse dns to the line they provide like mail.mydomain.com

You can also have an external company handle your DNS and they will add the necessary records.

Here is a link of reviews of companies that provide that service

I for this to work properly, your external DNS  reconfiguration must be configured at the Authoritative DNS server.

The load balance method is probably done using round robin method.  To guarantee dead peer detection, some type of keep alive packets are maintain between the  load balancer and the Authoritative DNS server.

Perhaps the problem you having is by designed since it is really a single host but two different IP addresses.  That means that you either enter hostname only once or already defined with the service in question.
NS record is always an IP address. How would you resolve it using not yet known IP of DNS server?

You need to juggle DNS content if one link goes down for longer period...
Example of


configuration in authoritative DNS

corp NS wan1balance

corp NS wan2balance

wan1balance A x.x.x.x

wan2balance A y.y.y.y



www CNAME www.corp.foobar.com<http://www.corp.foobar.com>

ftp CNAME ftp.corp.foobar.com<ftp://ftp.corp.foobar.com>

mail CNAME mail.corp.foobar.com
