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. The other (eth1, 192.168.1.2) is only used for a VPN, where all (udp) traffic originates from outside our network. I have created a second

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. The local net connect to the internet via the gateway 10.0.0.1 and SNAT is applied on the firewall. It worked but sometimes there are some

Hello all, Yesterday I noticed that my system was "leaking" traffic towards the 10/8 network, I have shorewall installed on multiple machines ranging from single interface devices to ones with 10+ interfaces. I tested all the boxes and they are showing the same behavior. All systems are CentOS 3.4, 2.4.21-27.0.2.ELsmp. Shorewall version: 2.2.1 For the host mentioned is a single

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
