General Discussion / Creating a Dynamic DNS provider on OpnSense for secure updates from the WAN

« on: November 13, 2024, 12:05:35 am »

Hi,

I have fixed IP address on one of my Orgs OpnSENSE firewalls.

I'm wondering if it is possible to create Dynamic DNS Server on that firewall and take Secure Updates from other OpnSense Firewalls on the Internet rather than pay a Dynamic DNS provider.

If so, any hints on how?

PS: Everything I read on DDNS and Opnsense relates to the ddclient and while useful for the remote OpnSense FW not useful for the above use case.

23.7 Legacy Series / dpinger and "Disable Host Route"

« on: August 28, 2023, 04:39:29 pm »

If you use Gateway Monitor IP addresses like 8.8.8.8 & 8.8.84.4 you want to "Disable Host Route" for these addresses otherwise you loose access to a DNS server when the route goes down.

I'm finding if I "Disable Host Route" and ensure the route is removed dpinger will just declare the gateway as up.

I'm guessing dpinger relies on these routes rather than binding the the specific interface and sending out over that interface only.
