What you wish to accomplish can be done, but it does require some work. Let me first clarify that this has nothing to do with iptables or ebtables. You should think of NICs (including bridges) as windows: they open on the outside, not on the inside. Thus both eth0 and br0 send packets away from their outer side, i.e. on the ethernet cable, and receive ...

I notice that during the OpenVPN client initiation, the route gateway is shown as 10.0.16.129, yet the OpenVPN server & vpn network settings point to a subnet 10.0.0.0/16. Perhaps assigning too large of a subnet there is blocking routing to the DNS server, 10.0.0.2? Other than that, this is already preventing "leaked" DNS -or anything for that matter- ...

A MAC Address is a physical signature that exists on every hardware that can connect to a network. It is also always unique. It's basically a low level unique id for your network device. Now, you cannot communicate knowing only the port information because multiple devices could listen/send to the same port. It it the base of communication in a network! ...

You need to be able to identify a connection at all levels of the network stack. The mac address ONLY identifies the LAN adapter in the ethernet layer (Layer 2 Simplified OSI model). The IP address (TCP and/or UDP) ONLY works in the IP layer (Layer 3). Not all communication using IP goes via ethernet. IP can be send over other Layer2 layers where there are ...

MAC is required for a couple of reasons, the biggest of which is that IP addresses are not (necessarily) unique. Before a computer has an IP address, it typically requests one on the network by using a service called DHCP. At this point, the computer sends a broadcast message to the entire network saying “Hey, I don't have an IP address. My unique ...

These two statements push "remote-gateway 52.58.43.124" push "remote-gateway 10.0.31.207" don't make any sense. First, they contradict each other. Second, this kind of push option does not exist: from the online manual This is a partial list of options which can currently be pushed: --route, --route-gateway, --route-delay, --redirect-gateway, ...

Ok, I was able to have my public interface as my default. I've done this by adding a gateway for that interface and removing the one from the private interface. I was not getting any gateway before on the public interface (at least, this is what I thought), but that has been fixed by removing the gateway from the private one, then setting public to dhcp. I ...

I finally found out the reason by luck and wanted to share: The problem were electric devices. I.e. everytime the light was switched on, the powerlan connection was disturbed.

You could configure PC B to act as a router between the two subnets, e.g., see Setting up an Ubuntu Wired/Wireless Router as explained at the Official Ubuntu Documentation site. Alternatively, for accessing just the web services running on C from A, you could install proxy server software, such as Squid or one of many other proxy server applications, on B ...

I got the answer by myself. The issue was with the iptables command. It was necessary to specify the output device and also set the forward policy. iptables -t nat -A POSTROUTING -o rmnet_usb0 -j MASQUERADE iptables -P FORWARD ACCEPT After that internet becomes accessible on the linux box side. Hope this helps somebody in the same situation.

Try to set Allow outbound instead of Allow inbound to Yes for IMAP. Although in your setup IMAP is for receiving mail, the firewall rule probably looks at the way you establish a connection (which is outbound to your e-mail server).

The NIC priority could be incorrect. With both NICs connected open Control Panel\Network and Internet\Network Connections Now press Alt + n to open the Advanced menu and click on Advanced Settings. Now select the NIC that you want to be the primary interface and move it to the top using the arrow buttons.

The manual states: bypass-dhcp -- Add a direct route to the DHCP server (if it is non-local) which bypasses the tunnel (Available on Windows clients, may not be available on non-Windows clients). so there is no certainty at all this exists on iOS. I do not have an iOS device, please let me know whether you find any evidence that this instruction works. ...

The finding was that the Fedora 21 and 22 "Server" install does not include the required files to enable fib_rules.c to run, which controls the multiple table rules. The packages that are needed to make Policy Routing with multiple tables are: kernel-headers, kernel-devel, and libnl3-devel Once these were installed the policy routing works correctly.
