Hi, i have a question if linux is able to do the same thing that commercial wan simulators do (which cost 7000 $ or more). Basicly i want to use the following setup. Linux Router Machine 192.168.0.1 192.168.1.1 Eth0 192.168.10.1 Eth5 192.168.2.1 Eth1 192.168.100.1 WEB Server. 192.168.3.1 Eth2

Hi, I met a problem when using bridge with netfilter. The kernel version 2.4.20, and the patch is bridge-nf-0.0.10-against-2.4.20.diff. Our firewall configuration is as follows, eth3,eth4,eth5,eth6 configured as a bridge with an IP address 10.0.0.1.

Hello all, I am new to Linux Ethernet bridging. Let me first start with what I am trying to achieve. Well you see - I am attempting to have 2 main firewall running at the same time - one as a master and the other one as a slave.

Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either...

All, I've got a machine running CentOS 5.3 and this machine has got 2 - built-in 1 Gig NICs and a expansion card with 4 - 100 Meg NICs. For whatever reason at install time, it made the expansion card eth0 through eth3 and the internal ports eth4 and eth5. And by default the 'machine' is known on the network by the eth0 NIC, so my throughput is limited to 100 Mb. How can I force

I''m having another little problem with my new firewall.

Hi, I'm on a Dell VEP 1405 running Debian 9.11 and I'm running a few tests with various interfaces given in PCI passthrough to a qemu/KVM Virtual Machine also running Debian 9.11. I noticed that only one of the four I350 network controllers can be used in PCI passthrough. The available interfaces are: *# dpdk-devbind.py --status Network devices using kernel driver

Hi all, I''m trying to set up a computer with 2 routes to the internet, much as described at http://lartc.org/howto/lartc.rpdb.multiple-links.html .One of my interfaces (eth5, 192.168.2.2) is only used for traffic originating inside the network.
