Describe the problem

After updating to the latest 0.46.0, the DNS stopped working, from log it seems like route issue:

	* update system routes: 1 error occurred:
	* add route 10.220.0.53/32: failed to add for key XXXX/32: route not allowed

To Reproduce

Steps to reproduce the behavior:

  1. Have DNS via additional route and update to 0.46.0

Expected behavior

TLDR; you cannot route resources/put static IPs from NetBird's network range, this is expected to contain only Peer's internal IP addresses. This is why we decided to use normally unusable CGNAT range.

So from my notes:

The error happens many times:

2025-06-09T14:44:27+02:00 ERRO client/internal/routemanager/manager.go:405: failed to update system routes during selection: 1 error occurred:
	* add route 10.220.0.53/32: failed to add for key 10.220.0.53/32: route not allowed
2025-06-09T14:44:27+02:00 WARN client/internal/routemanager/manager.go:418: no active handler found for route dns endpoint|10.220.0.53/32

The route seems to be valid in Network Map:

    {
      "ID": "clrm....nvd0",
      "Network": "10.220.0.53/32",
      "NetworkType": "1",
      "Peer": "yWNL.......b4LkM=",
      "Metric": "9999",
      "Masquerade": false,
      "NetID": "dns endpoint",
      "Domains": [],
      "keepRoute": false
    },

BINGO!

  1. Your NetBird tenant's IP range is 10.220.0.0/16 by the looks of it. I have initially assumed this would come from the standard CGNAT range 100.64.0.0/10 and therefore wasn't alarmed at all.
  2. You are trying to route 10.220.0.53/32 which comes from NetBird's range
  3. Validation fails at validateRoute() -> r.wgInterface.Address().Network.Contains(addr)

Closing this, as the root cause is explicitly and without a doubt identified as a user configuration issue.

The only thing we could improve about it would be adding additional validation in the API to prevent creation of routing rules overlapping with NetBird network range.

Thanks for the info! Sadly it was discovered by the update.

Yeah, sorry it turned out this way. Looks like we have added this piece of validation last week because it was giving issues for others.
