Title: Issues with 26.1, unable to connect to internal network services
Post by: tessierp on March 27, 2026, 11:42:38 PM
Hi,

Even since version 26.1, I have been experiencing issues, services that worked that I can no longer reach.  tried to take my time to understand some of the problems I was faced with but I'm struggling; I recently migrated to the new rules system which was a source of problems initially but I noticed that NAT rules which were created for me automatically before when setting a WAN rule that is no longer happening (Destination NAT); I don't think this is part of my issue since the Destination NAT for my Teamspeak entries were already there from what was created before. I'm able to access Teamspeak from the outside however, from the inside; I use something like teamspeak.mynetwork.net which is configured through Cloudflare and internally I use Unbound DNS to override the destination. But that doesn't seem to work anymore, no matter what IP I put in Unbound DNS I never seen it. Are there any issues with Unbound DNS at the moment?

If you want to reach your External WAN IP Address via a Domain Record that is known on the Internet with the same Domain Record from your LAN then you need to configure that correctly.

Some options :
- Reverse NAT a.k.a. NAT Loopback.
But not really what you want to be honest...
- Reverse Proxy + The correct DNS Records.

Or just use IPv6 only ofcourse :)

Well I do have a reverse proxy, I use HAProxy for that. And I used UnboundDNS internally to send to the right server. All of that worked before 26.1.
