You shouldn't need to set the ip_forward = 1 unless the interface is acting as a NAT for the other devices, which shouldn't be the case if you've set them up as a bridge. Example Here's my KVM server setup which has a bridge device, br0, with the physical ethernet device, eth0 + all the interfaces for the KVM guests. $ brctl show bridge name bridge id ...

The whole setup is too long to be described here, also there are multiple ways how you might want to configure it, so to provide an overview: You need to setup OpenVPN server. I would advice to do it on a VPS with external IP. Setup OpenVPN clients on other servers and android devices to connect to your OpenVPN server. You can find quick ...

Gilles' answer is completely correct, but there is also another potential cause for this. There was a bug in version 2.3.0 of OpenVPN which would disconnect clients when sending large chunks of data: https://community.openvpn.net/openvpn/ticket/263 This issue only occurred when using TCP. UDP was completely unaffected.

You have the symptoms of an MTU problem: some TCP connections freeze, more or less reproducibly for a given command or URL but with no easily discernible overall pattern. A telltale symptom is that interactive ssh sessions work well as long as you don't run commands with large output. See Can't access select https sites on Linux over PPPoE for an ...

I cannot say if VPNC will or won't work with Checkpoint, and in the past when I've attempted to use VPNC with Aventail/Nortel it did not work for me, so I reverted to using the native client software that was included by Aventail/Nortel on Fedora/CentOS/Ubuntu systems. I cover some of this at a highlevel on my blog in this article titled: Setting up Aventail ...

You have to check whether the firewall configuration allows forwarding: iptables -L -nv But it is not enough to configure the firewall to allow routing. The routing feature itself must be enabled in the kernel. If the kernel does not even try to route then it does not matter whether the firewall would let the packets through or not. You can check the ...

I don't have the full output pre-grep because my scrollbuffer filled up, but: # ip addr show dev eth0 |grep 192.168.[12] inet 192.168.1.1/16 scope global eth0 inet 192.168.1.2/16 scope global secondary eth0 inet 192.168.1.3/16 scope global secondary eth0 inet 192.168.1.4/16 scope global secondary eth0 inet 192.168.1.5/16 scope global secondary eth0 ... ...

If you are using Fedora, go to Fedora instructions. Similarly, don't use Fedora's instructions on Debian, and definitely don't follow instructions on random websites blindly. Distributions do change over time, configuration files are at different places (or the configuration is done in a completely different way).
