#StackBounty: #networking #server #vpn #iptables #openvpn OPENVPN: MULTI: bad source address from client

Bounty: 50

I struggled this problem for two days, but the problem is still here. Hope someone can provide suggestion or the way how to diagnose it.

What i want is let all client visit Internet over the OpenVPN server. Therefore, I first follow instructions Routing all client traffic (including web-traffic) through the VPN. After configuration, and setup iptables, the connection between VPN server and client succeeds, but the client can not visit any website (the brower is hang there). The ping from server and client are OK.

I checked log at the server, and there are some records like:

   Oct  3 09:16:21 iZbp15fejv9adv7o3izfm1Z ovpn-delta[1827]: laptop/131.202.XX.XX:59701 UDPv4 READ [93] from [AF_INET]131.202.XX.XX:59701: P_DATA_V1 kid=0 DATA len=92
    Oct  3 09:16:21 iZbp15fejv9adv7o3izfm1Z ovpn-delta[1827]: laptop/131.202.XX.XX:59701 MULTI: bad source address from client [131.202.XX.XX], packet dropped

where the IP: 131.202.XX.XX is my laptop IP address. This record is explained in “MULTI: bad source address from client , packet dropped” or “GET INST BY VIRT: [failed]”, why this IP is not 10.8.0.6 (tun0) at my laptop, and the detail implementation for the problem? My laptop connects to Internet using WIFI, and it is a device that runs openvpn --config client.conf.

As this is very simple example, Do I have a way to avoid this error, or any sample to config client-config-dir and create a ccd file

the /etc/openvpn/delta.conf at the server:

# Which local IP address should OpenVPN
# listen on? (optional)
;local a.b.c.d

For IP router configuration, I added the iptables to /etc/rc.local, so that iptables can be changed at server startup.

#I also tried comment out first three instructions, but still does not work

iptables -A FORWARD -j REJECT
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE

service dnsmasq restart

exit 0

and the /etc/sysctl.conf

net.ipv4.ip_forward=1

telnet serverIP 80 is OK. In the server: /var/logs/syslog:

Is there any solution?

#StackBounty: #networking #ubuntu #virtualbox #virtual-machine VirtualBox network stops working

Bounty: 50

I have VirtualBox 6.1 running on Windows 10. It is running virtual machine with Ubuntu server 18.04 LTS. It can work couple of weeks without any issues, but sometimes VM completely looses network. It is not available to connect to (using ssh like putty) and services, which are running in VM also cannot connect to anything (cannot send email, resolve DNS). The VM itself is running, I can control it using VirtualBox window.

Restart from Ubuntu (shutdown -r now) does not help. After restart it still does not have network. Complete shutdown (shutdown -h now) and then start helps.

What could be wrong? How I can investigate and find the reason of the issue?

#StackBounty: #networking #docker #ping unRAID OS Docker container connections

Bounty: 50

I am currently setting up an UnraidOS server and have a bunch of docker images on my machine. I recently installed a docker container that pings the others based on IP and reports the uptime status. The uptime docker is connect to the bridge network, and can access ONLY the other docker containers on the bridge, not anything else on the network. What would I need to do in order to allow my uptime docker to reach other IPs?

My unraidOS server has an static IP of 192.168.1.14

Docker 1: 192.168.1.14:8401 (bridge)
Docker 2: 192.168.1.14:8402 (bridge)
Docker 3: 192.168.1.14:8403 (bridge)
Uptime Docker 4: 192.168.1.14:8400 (bridge)
Docker 5: 192.168.1.15 (custom: br0)
Docker 6: 192.168.1.16 (custom: br0)

My "Uptime Docker 4" is able to ping and connect to Docker 1, Docker 2, and Docker 3 as they are all on the "bridge" network time. Docker 5 and Docker 6 are both on the "custom: br0" network so that they have their own IP addresses and my "Uptime Docker 4" can’t connect to it since it is on a different network.

What would my solutions be so that Docker 5 and Docker 6 still keep their IP yet is still accessible by Uptime Docker 4?

I have another PC connect to my network with an IP of 192.168.1.103 and "Uptime Docker 4" is able to ping it. It still can’t ping "Docker 5" and "Docker 6" even though those IPs are assigned just like my PC.

#StackBounty: #networking #vpn #split-tunnel Networking problems using free version of ProtonVPN

Bounty: 50

I am using the free version of ProtonVPN on my Windows 10 Laptop. I connect the laptop to the internet using Wifi from Cable Internet.

My ProtonVPN is configured for split tunneling – Only the Brave Browser on my laptop is to use the VPN & all other applications would be excluded from the VPN tunnel.

Proton VPN Settings

I have 2 problems

  1. My problem is that my native connection (the one that is used by the other browsers) behaves differently when my VPN tunnel is on. This is an occasional problem doesn’t happen all time. I am unable to reach several sites on my other browsers (unable to connect to the site). If I shut down the VPN, the same sites now start opening through my excluded browsers. Sometimes just shutting down the VPN works, sometimes, I also need to run "ipconfig /renew" before it starts working – even this is not foolproof, sometimes it just doesn’t work for a long time.

  2. When I startup my ProtonVPN, while it’s connecting to the VPN server & tunneling my laptop has now internet connection till the time it’s done establishing the tunnel. No other browser (the ones excluded from the VPN) can connect to anything till then.

The 2nd issue is not a big one (it’s just for a few seconds usually), I mentioned it just in can help in trouble shooting the issue. But the 1st one is almost making me consider giving up using VPN at all.

Are there any solutions for this?

#StackBounty: #networking #dell #ethernet Issues with local network when using Dell TB16 dock's ethernet connection

Bounty: 50

I’ve got a Dell Thunderbolt dock (TB16) on my Dell XPS 13 notebook. When I use the ethernet connection on my dock, local websites (192.168.1.x, like web interfaces of my printer, Pi-Hole, ZTE H369A router) don’t work properly because of corrupted data. Printing on my Samsung network printer (M2070) doesn’t work; it prints just a couple of random characters instead.

When I set the speed of the wired connection to 10 or 100 Mb/s it works fine, but when I set Link negotiation to Automatic or Ignore or when I set Speed to 1 or 10Gb/s, I get corrupted data.

enter image description here

When I go to a local webpage, I get Uncaught SyntaxError: Invalid or unexpected token or Uncaught SyntaxError: Unexpected token ']' in the console. The response (in this case jquery-1.7.2.min.js) is malformed:

Other (non-local) websites are working fine and using another ethernet adapter (or Wi-Fi) is working fine too. Even my router interface (192.168.1.254) is working fine when using a reverse proxy (router.mypersonaldomain.example). That might be because my internet connection is just 65 Mb/s, but I’m not sure if that’s the reason.

I’m having this problem for a couple of years now and updating the firmware drivers or Ubuntu didn’t and I’m curious what the exact problem is. The problem also exists when using a Ubuntu Live USB and also on both Chrome and Firefox.

How do I find out what the exact problem is? Before I’m looking into solutions, I want to know what the technical issue is.
