* sorry for the 2 previous schemas, they came out a mess. I hope this one is understandable. hi: I have this 2 boxes set up like this: 2020::2/128 2020::254/128 3030::254/128 192.168.0.2/24 192.168.0.254/24 192.168.30.254/24 +-------+ eth0 eth3 +-------+ | |==================== | | eth1 | A | | B | ---- | |

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:

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

Hello, I need some help about a routing problem on a complex configuration. The problem is that I can''t reach from services outside from my DMZ. The scenario is a gateway linked to three internet connections, so that I used three distinct iproute2 tables for routing. The gw is running ipvs for balancing over the dmz''s servers. DMZ servers are on 192.168.1.0/24 network, .

I''ve applied julian''s paches to a 2.6.14 gentoo kernel with the appropiate options enabled, and i''m using a modified version of the mpath2.sh script also available on julian''s site http://www.ssi.bg/~ja/ Overall everything works nearly perfectly. Incomming connections to either the fios (PPPoE) connection, or cable modem get routed back out correctly. The

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

We've been running ipv6 for a year or so now, but some of our newer instances (all on an ESX cluster) are not working. It looks like it's all of our Centos 6 instances. I'm hoping someone can point me in the right direction... tshark indicates that it's neighbor discovery that's failing: <centos666.peak.org> [26] # cat ../network NETWORKING=yes

Hi I used the command "ip -6 addr add 2001:DB8:CAFE:1111::12/64 dev eth0" to add ipv6 address and can see it in ifconfig but can't ping it Why? Thank you # ping6 2001:db8:cafe:1111::12 PING 2001:db8:cafe:1111::12(2001:db8:cafe:1111::12) 56 data bytes >From ::1 icmp_seq=1 Destination unreachable: Address unreachable >From ::1 icmp_seq=2 Destination unreachable: Address
