When I start my eBlocker on above named Raspi4, the eBlocker kickes away the Fritz!Box and overtakes its place - no Internet any more. If I take my PI400, the eBlocker works fine. The Raspi4 itself with Bullseye works fine but homenet crashes, if it is connected to. As a workaround i connected the raspi4 with a new eBlocker installed by an USB to Ethernet Adapter, but it doesn't work. The same Raspi4 with Bullseye, is connecting immediatly to the Internet. Is it possible to teach eBlocker (for Example by editing a config-File) to use the adapter instead of the build-in Ethernet-connection?

Best to all, Rob

Image attached of the error I'm receiving (mouseover provides the "413..." portion).  Required information regarding my configuration listed below.

• Hardware you use for running eBlockerOS
  • Raspberry Pi 4B 2GB
• eBlockerOS version as well as filter lists version
  • 3.2.3
• eBlocker network mode (auto, individual or expert)
  • Automatic
• eBlocker network settings (IP, mask, gateway)
  • 192.168.7.166, 255.255.255.0, 192.168.7.1
• Which devices runs DHCP server? Router/external, eBlocker or client fixed IP?
  • Router
• IPv6 disabled for client/network?
  • Yes
• eBlocker DNS firewall settings
  • Use eBlocker as DNS (custom; pointed to Umbrella)
• Client network settings (IP, mask, DNS, gateway)
  • N/A
• Whether eBlocker’s https integration is enabled for client 
  • N/A (but yes)
• Client browser and OS version (i.e. FireFox 80.1 running on macOS 13.4)
  • Safari 26.3.1
• Additional non default Blockers enabled? (like DuckDuckGo, Consent-Blocker, custom lists etc.)
  • No
• HTTPS Auto Trust App enabled?
  • Yes
• Exact way or a link / screenshot to reproduce the issue
  • See attached image
• If VPN or Tor is enabled for the client in eBlocker (and which VPN provider you are using)
  • N/A
• Are automatic updates enabled?
  • Yes

In short the speedtests when using eBlocker on a client the bandwidth is impacted too much.

Testing using Windows client, https enabled, cert added to firefox where the tests are made.

Test sites speed.cloudflare.com and fast.com.

eBlocker version 4 up to date. On a VM. First 2 GB memory, increased to 3 GB (yes not a multiple of 2) but when on 2 GB the usage peaked only to 90%. Removed the firewall from the virtio NIC, I am using VirtIO NIC as is the most performant. I have tested increasing to 2 and 4 queues for this NIC. MTU is same as bridge. 

For CPU it was as per the VM definition with x86-64-v2-AES but I have also tested with "Host". The host cpu is modern Ryzen 5.

Results: eBlocker enabled on client, 10 Mbps. eBlocker paused for device, 160 Mbps fast.com, 128 speed.cloudflare . ISP contract 510 Mbps.

WiFi connection on 5 GHz band (channel 116), link speed 961/1081 Mbps, 802.11ax protocol. Sec: WPA3-Personal.

This particular corner of the house doesn't get full speed despite strong signal so the question is not why not full 500 Mbps but why 10 Mbps with eBlocker, 160 Mbps without ? Of course there will be a hit from doing MiM inspection but is this 16 X impact expected? Not a complaint, only wanting to understand and if there are suggestions on what to check.

Perhaps some background information first: I have been using eBlocker for years. I originally purchased the white cube and have been very satisfied with it.

Since switching to the UniFi network (Cloud Gateway Fiber incl. various access points and switches), I have been experiencing unstable internet access when eBlocker is active as a DNS server and filtering traffic. The DHCP server is the UniFi router (before the switch—most recently a FRITZ!Box 5590 with Wi-Fi via Apple Airports—I used eBlocker as the DHCP server).

I have installed eBlocker 3 on a Raspberry Pi 4, which I used successfully for years. In addition, as part of my problem analysis, I purchased a Raspberry Pi 5 with 8 GB RAM and installed eBlocker OS 4 on it. Both eBlockers basically work. Both use the ISP’s DNS server or 8.8.8.8 as a custom DNS.

Currently, I am experimenting with eBlocker 4 only. eBlocker running OS3 is shut down.

However, when I set the IP address of the primary DNS on the UniFi router to the eBlocker, things become unstable. Websites load sporadically (not systematically) extremely slowly or not at all (browser error messages indicating that the internet connection has been interrupted). Games such as Mario Kart Tour on the iPad get stuck during startup, even though all referenced pages are whitelisted in eBlocker. When I perform manual recording, I no longer see any accesses where eBlocker is “enabled.” Nevertheless, the app refuses to work.

HTTPS is enabled on all devices and the certificates are installed. When I run functional tests, I only see “green check marks” everywhere.

I have tried all kinds of configurations. In no setup have I achieved a stable network with eBlocker integrated. Listing everything here would go beyond the scope and, in my opinion, would not be very helpful anyway.

If I remove eBlocker from the network (shutdown), the network runs very well and very fast—albeit with all the usual disadvantages that come with that.

I would now like to try again in a more systematic way, ideally with the help of eBlocker experts. I would not consider myself a beginner, but I am certainly not a networking expert either.

Maybe someone here can still help me—I am close to giving up. Thanks in advance!
