DNS replication between sites

[mickeyil]

Hi,

I have quite the same situation as in an older post here:
Re: Pfsense 2.3 DNS replication options

I would like to combine auto hostname registration in openvpn from 2 sites, and be able to resolve them by referencing the hostname: i.e. each client should be able to "ping hostnameX" from every site.

I got it to work on a single site, with the "OpenVPN clients" option turned on DNS Resolver, and set push "dhcp-option DNS ..." in OpenVPN server configuration.

Has anything changes in the past 4 years to allow this? I'm running pfsense 2.4.5-p1 .

Thanks!
