newly several software on computer can't connect / OPNsense 24.1.7-amd64

[E-J-D]

Hi,

I am using OPNsense for years without noteworthy problems. Level: advanced, but far from pro 😂.

Running today OPNsense 24.1.7-amd64. WAN is Vodafone Cable in DE.

But for some days now I have problems with different software on my and other computers of my family which are that they can't connect anymore to their servers.

Worst thing is that Wireguard on my laptop doensn't work anymore. Of course, Wireguards says it is connected (what it does even when there is no internet) and it is sending data out but no data comes in. When I use my mobile hotspot it works. Today I exchanged the OPNsense with old boy DD WRT router. With that setup Wireguard and other work well - no connection problems with Wireguard, Discord, COD-MWIII, etc.

As I didn't changed anything on my OPNsense, expect updating every week, I am not sure what happened. I already hustled thru all settings. But nothing looks suspicious.

Weird is for me that openVPN still works.

Are there any known problems from this direction? Any idea is appreciated.

Greetings
Eike

Arrrg... today I installed a fresh OPNsense 24.1 on a separate SSD. It works. After I restored the backup from yesterday... same problems as yesterday. It seems that something is broken in my config.

I'd like to ask you to please keep updating this thread should you find out what exactly broke this part of your config, because I have a similar issue.  :'(

After a few hours of investigation... I gave up and reinstalled OPNsense completely. Works (again) like a charme.
