Problem waren die Treiber von RealTek. Die NIC's von denen scheinen keine perfekte Unterstützung zu haben. Installieren von dem Plugin os-realtek-re fixt das Problem.

Thanks Mr.Goodcat, issue was fixed with adding the plugin for RealTek drivers. No DHCP issues.

Mhh, I can still return my Firewall PC (Forums Mini). Any good recommendations for a very small PC used for Firewall/Routing + Ubquiti Server (basically everything network related) for under 150€?

Thank you guys. It is also recommended here: https://www.thomas-krenn.com/de/wiki/Realtek_NICs_in_OPNsense
I'm trying to install (/ui/core/firmware#plugins) os-realtek-re and let you know if it fixes the issue.

Hi,
so I did as you said tried to renew the DHCP lease when it went down. But to no avail, still had to reboot to fix it.
However I noticed some strange things before rebooting (see screenshots).

Straight after loosing the connection I went to check on the OPNSense dashboard. The WAN interface there had both a configured, and correctly looking IPv4 and IPv6 address. Logs did not have anything suspicious. But no internet was available for me.
So I checked the Interface->Overview->WAN tab and tried to renew the DHCP lease. This is where the log you see in the screenshot comes from. This did not fix my issue.
In the german forum someone suggested turning of IPv6 on the WAN interface (Interface->WAN->IPv6 Configuratio Type set to None), which I did, however this also did not solve the issue.
When coming back to the overview I noticed that the WAN IPv4 address now was pointing to 0.0.0.0, which of course is wrong (IPv6 was missing as I just turned it off).

So all in all - DHCP lease renew did not fix the issue but resulted in some weird logs. The issue could only be resolved by rebooting from website.
Any other ideas?

Hi. danke für den Tipp.
Die vorgeschlagenen Einstellungen, dienen nur dem Speedup und nicht des Connectivity Problems, wenn ich das richtig verstehe?

Ich hab mal beides so eingestellt und würde sagen, dass es so marginal schneller ist. Nun bin ich mir aber unsicher, ob es eine gute Idee ist, den IPv6 Traffic komplett auszuschalten. Das hört sich nach einem sehr großen Hammer an...

Hi,
my OPNsense looses internet connection every 3-4h. Restarting the box fixes the issue. While the problem occurs, the WAN IP field on the WebGUI is blank. However, OPNsense is reachable from within the LAN network.
I have the Vodafone Cable 1000 Plan and use OPNsense 23.7.10_1-amd64.
My network looks somewhat like this:

Code: [Select]

 
     WAN / Internet
            :
            : Vodafone Cable 1000
            :
      .-----+-----.
      |  Modem    |  https://www.vodafone.de/hilfe/router/station.html, bridge-mode
      '-----+-----'
            |
        WAN | IP or Protocol   (DHCP)
            |
      .-----+------.   
      |  OPNsense  |  WAN: DHCP / DHCP6 | LAN: static, 192.168.1.1 / track interface
      '-----+------'   
            |
        LAN |  192.168.1.0/24 
            |
      .-----+------.   
      |  Switch       | TP-Link TL-SG108E, Gateway: 192.168.1.1,  Subnet: 255.255.255.0 | LAN: static, 192.168.1.2
      '-----+------'   
            |
        LAN | 192.168.1.0/24 
            |
      .-----+------.   
      |  Clients      | (PC's, WIFI AP, ...)  
      '-------------'

Would like to note that the Service "dhcpd6" is not running in the WebGUI at all times. I also checked log files (System->Logging File->Default) but couldn't find anything I would deem error indicating.

I also have the feeling that access on Websites is now slower than before when using the Vodafone Station as Router/Switch.

I'm relatively new to networking, hence the solution might be obvious, but just not for me. Do you guys have any ideas where I should look or how I can fix any these issues? Thanks!

Moin,
bei mir disconnected sich alle 3-4h das OPNSense vom Internet. Restart fixt das Problem. Während das Problem besteht, ist die WAN IP aus der OPNSense auch nicht vergeben / leer, die Box selber aber via ssh / WebGui aus dem LAN erreichbar.
Ich habe bei Vodafone den Cable1000 Plan und verwende OPNsense 23.7.10_1-amd64. Mein Netzwerk sieht ca. so aus:

Code: [Select]

 
     WAN / Internet
            :
            : Vodafone Cable 1000
            :
      .-----+-----.
      |  Modem    |  https://www.vodafone.de/hilfe/router/station.html, bridge-mode
      '-----+-----'
            |
        WAN | IP or Protocol   (DHCP)
            |
      .-----+------.   
      |  OPNsense  |  WAN: DHCP / DHCP6 | LAN: static, 192.168.1.1 / track interface
      '-----+------'   
            |
        LAN |  192.168.1.0/24 
            |
      .-----+------.   
      |  Switch       | TP-Link TL-SG108E, Gateway: 192.168.1.1,  Subnet: 255.255.255.0 | LAN: static, 192.168.1.2
      '-----+------'   
            |
        LAN | 192.168.1.0/24 
            |
      .-----+------.   
      |  Clients      | (PC's, WIFI AP, ...)  
      '-------------'

Anzumerken wäre, dass der "dhcpd6" Service nicht läuft, wobei ich mir nicht ganz sicher bin wie wichtig das ist. Im Log (System->Logging File->Default) steht nichts, was mir krumm vorkommt.
Ebenfalls habe ich das Gefühl, dass der Zugriff auf Websites nun länger dauert als mit der Vodafone Station als Router/Switch.

Ich selber bin auch noch nicht komplett fit, was das Netzwerken angeht, also vielleicht ist die Lösung auch offensichtlich. Hat jemand einen Vorschlag, wo das Problem liegen könnte und was ich machen kann? Danke!
