DNS refuses to update
PFsense local –--> OpenVPN tunnel ----> PFsense remote
PFsense local has domain override setup in DNS resolver pointing to the DNS server at PFsense remote. Works great and resolves all remote hosts.
Host at remote end used to be at 172.16.50.101. Changed it to 172.16.50.52. Updated entries in remote DNS server. Updated static entry in remote DHCP.
resolving the hostname on the remote end resolves the correct new IP.
resolving the hostname on the local end resolves the old IP.
restarted DNS service on both ends. Rebooted firewall on both ends. No avail...
"Register DHCP static mappings in the DNS Resolver" is not checked on either end.
Where is PFsense local pulling this old IP from?
Result of DNS lookup from local end: (172.16.100.18 and 172.16.100.19 are the DNS servers at the remote end)
