I have a 2.6.12(ubuntu-patchset), kernel recompiled with this routing options: [*] IP: advanced router [*] IP: policy routing [*] IP: equal cost multipath Load balancing is working great, but i have problems whits long term tcp flows (like msn-messenger or vpns or any other type of long term ip based conection). I assume this is because after a period of time, the per-host

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

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

Hello all I continue fighting with load balancing, I though it was easier :-/ Here is the script with my configuration #!/bin/sh IFI=eth0 IPI=192.168.10.155 NMI=24 IFE1=eth1 IPE1=192.168.1.128 NWE1=192.168.1.0 NME1=24 BRD1=192.168.1.255 GWE1=192.168.1.1 IFE2=eth2 IPE2=192.168.254.128 NWE2=192.168.254.0 NME2=24 BRD2=192.168.254.255 GWE2=192.168.254.254 ip link set $IFI up ip addr add

Hello Im having a problem similar to sawar Here is my configuration --------------eth1---192.168.1.128---------- -------------192.168.1.1 ISP router 1 | my | ---Eth0---192.168.10.157----| | | linux |

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:

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

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

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 all, i am setting up a load balancing network with failover, i have applied julian patch, but whenever i try to establish a new connection from any client node, it gives me two entries in the routing cache for that destination with different or same interface for those entries, but off the two entries only one route path is used for the transmission. the ip rule/route are as follows,

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

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 all, i am setting up a load balancing netwrok with failover, i have applied julian patch, but whenever i try to traceroute from any client node, it gives me two entries for that destination, but i get different interface for that entries, so it doesn''t forward my requests, i have done masquerading for client nodes, the ip rule/route are as follows, ip rule add prio 222 table

Rowland, Thank you for all your help, I agree that this is not a Samba issue. Given rhat it works without the firewall. It' either a ufw or Windows 8.1 issue. Louis, Applied the rules you suggested to ufw exactly as written. No change. Still cannot connect with firewall enabled. Same error mesage as before "Cannot mount location ...". ufw log set to medium and copied below.
