I use OpenVPN for that and a basic configuration with no encryption. OpenVPN is shipped with most distributions. It needs "tun" kernel module. Commands I used. First machine: openvpn --remote 192.168.111.177 --dev tun --ifconfig 192.168.4.52 192.168.4.51 --verb 1 --comp-lzo \ --resolv-retry 999999 --ping-restart 120 --ping 6 --port 5123 --fragment 1400 --mssfix 1400 \ --shaper 5000 Second machine: openvpn --remote 192.168.111.175 --dev tun --ifconfig 192.168.4.51 192.168.4.52 --verb 1 --comp-lzo \ --resolv-retry 999999 --ping-restart 120 --ping 6 --port 5123 --fragment 1400 --mssfix 1400 \ --shaper 5000 --shaper 5000 - it is about 5 kB/s Change --remote addresses to match your IP addresses. After running these two commands, you should be able to ping 192.168.4.52, 192.168.4.51 from both hosts. -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html |
