I have centos 6 running kvm. IPv4 works perfectly works. But I am having some problem with ipv6, looks like its bridge routing problem but stuck. here are my bridge detail: bridge name bridge id STP enabled interfaces br0 8000.000af75613f2 no eth1 vnet1 br4 8000.000af75613f0 no eth0 ip -6 route shows : unreachable ::/96 dev lo metric 1024 error -101 mtu 65536 advmss 65476 hoplimit 4294967295

hi i have a strange night with our firewall ;) i wanted to utilize the icmp redirect packages to connect our to different networks on the same segment i have a lot of these messages in dmesg: Redirect from 10.0.0.2 on lo about 152.66.235.1 ignored. Advised path = 0.0.0.0 -> 0.0.0.0, tos 00 --- with tcpdump i saw strange packets crawling on the lo interface ;) IP 10.0.0.2 > 0.0.0.0: icmp

Dear all, I''ve the following problem with routing + NAT: If I''ve two ISP and I''m using two nexthop in default route with MASQUERADE on both ISP links, I see routing cache regenerated, but sometimes packets sent to a new link (after cache regeneration) uses wrong source address for masquerading. Here is the config. I''ve two links to outside via two

Hi all, I have one bridge system (used for controlling bandwidth) connected to three different DSL ISP provider. I have the following setup below: - +-------------+ | br0 | | -> eth1 | -> DSL_1 | -> eth2 | +-------------+ | br1 | | -> eth3 | -> DSL_2 | -> eth4 | +-------------+ | br2 | | -> eth5

I can't get IPv6 routing to configure correctly despite everything I've read saying it should This is my network config on a fully-updated CentOS 5.8 system: # cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=my.hostname.com GATEWAY=aaa.bbb.ccc.ddd IPV6_DEFAULTGW=2a02:aaaa.bbbb::1 IPV6_DEFAULTDEV=eth0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0

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

So I do not want to run radvd on my public subnet (between the gateway and firewall). I am trying to set up the firewall's public interface. For now in ifcfg-eth0 I have the lines: DEVICE=eth0 BOOTPROTO=static HWADDR=00:40:F4:05:A8:F1 IPV6INIT=yes IPV6_AUTOCONF=no IPV6ADDR="2607:F4B8:3:1:0:40:F405:A8F1" ONBOOT=yes And in network I have: NETWORKING=yes NETWORKING_IPV6=yes

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. Yes, I would like to make use of Ethernet bridging in this scenario - as I understand it, all I need are two machines and STP enabled. I am running Debian

Hi, I think I found a problem in iproute or ubuntu kernel. I think that the "ip route get" returns wrong interface and gateway in an multipath routing environment on Ubuntu 6.06 LTS. I reported it also to launchpad as a bug: https://bugs.launchpad.net/ubuntu/+source/iproute/+bug/105521 The easiest way to reproduce it is to start an Ubuntu 6.06 LTS Live on a system with three

Hi, my box is connected to 3 networks, eth0 eth1 wlan0. I want "my" traffic to go via wlan0 and everything from eth1 NATed to eth0: eth0 192.168.1.10/24 eth1 172.16.1.1/12 wlan0 192.168.10.190/24 I first tried this with two single hosts: iptables -A POSTROUTING -j MASQUERADE -o eth0 -t nat iptables -A POSTROUTING -j MASQUERADE -o wlan0 -t nat echo 200 Forw >>

Hi! I have many problems getting this thing to work. There''s a host with two network interfaces, where there are two routers to Internet in two separated networks. The host uses multihop routing for deciding to which router send the packets... but the routing decision is wrong made. Some packets with source address of one NIC, go to other network. I have a host with three NICs in it:

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... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services

Hello all, I''m using Red Hat Enterprise Linux 5 (with RH Virtualization) and a Dell Poweredge 2950 with 10 NICs. My virtual operating systems are all RHEL4, and I''ve installed 4 instances. I''m trying to set up the virtual operating systems so that the physical NICs are allocated to certain operating systems. Using the following tutorial:

Hi All :) I have three servers, all with centos 7 installed 3 days ago. I need on them "old" naming scheme (ethX) for network interfaces, because of that: # grep GRUB_CMDLINE_LINUX /etc/sysconfig/grub GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_node-XY/swap rd.lvm.lv=centos_node-XY/root rhgb quiet ipv6.disable=1 net.ifnames=0" net.ifnames=0 was added and afterwards I ran:
