Hi, [sorry for the crosspost, I don''t know whether this is a routing or ebtables problem] I want to redirect all HTTP traffic passing through my bridge to a squid proxy on another machine. However, setting up brouting as suggested in the ebtables examples doesn''t work and the packets get dropped on the floor completely. /\/\/\/\/\/\/\/\ +----------------------+ +-------------+ / LAN \-----|bridgeint bridgeext|----| Router | \ 192.168.0.0/24 / | |...

Hello! I have the following setup: 1) a connection to my ISP with a public IP (1.2.3.4) with the gateway 1.2.3.1 2) an allocated IP class with 64 addresses (5.6.7.192/26) 3) two LANs connected through two NICs: a) 192.168.0.0/24 on eth1 (192.168.0.1) b) 10.0.0.0/24 on eth2 (10.0.0.1) The IPs from the allocated class are all assigned to eth0. The networks are SNATed to the external IP and

Currently have a bridge working, would now like to add a third virtual nic so the machine can do nat as well to local users, however after a crazy amount of ready cant seem to get my head around it. Please help. Have a working bridge below (etc/network/interfaces and eth0 is the internet side interface so a virtual interface like eth1:0 would be nice :) auto lo iface lo inet loopback auto br0

Good morning, I''m writing to ask for collaboration in finding an improvement to a particular process. Today: To get traffic for our IDS sensors and a billing system, we collect everything at our core switches (2) by connecting a SPAN port from each switch to a server (so, 2 interfaces collecting traffic). That server changes the destination MAC address on all traffic to that of

...9;t seem to get any traffic out of the bridge into Squid in D0 (or through iptables in D0, for that matter). Information I''ve gathered so far is that I need net.bridge.bridge-nf-call-iptables = 1, and need the following command to have packets accepted by the bridge: ebtables -t broute -A BROUTING -p ipv4 --ip-proto 6 --ip-dport 80 -j redirect --redirect-target ACCEPT Not sure what I need from here. Are there other bridge or iptables settings I need to check? Is there some special iptables command I''m missing to have the network traffic go through D0 when bridging? Thanks, David...

...0.15 are ports of br0. Without countermeasures all traffic, including traffic vlan-tagged with tag 15, entering the physical device eth0 will go through the bridge port eth0. To make the 15-tagged traffic go through the eth0.15 bridge port, use the following ebtables rule: ebtables -t broute -A BROUTING -i eth0 --vlan-id 15 -j DROP With the above rule, 15-tagged traffic will enter the bridge on the physical device eth0, will then be brouted and enter the bridge port eth0.15, the vlan header will be stripped, after which the packet is bridged. The packet thus enters the BROUTING chain twice, the f...

...ge of trunk and any domU I wanted on vlan1 br1 = bridge of trunk.2 and any domU I wanted on vlan2 The latter config makes much more sense, but I could never get it working, nothing on br1 would ever work. Recently though I discovered I needed the following rule for ebtables: ebtables -t broute -D BROUTING -p 802_1Q -i trunk -j DROP which selects packets using dot1q encapsulation on interface trunk, and DROPs them from the broute table, which means they don''t get routed through the bridge. Because the bridge interface then doesn''t pick them up, they are available for the vlan logic...

Hi, I believe ndas devices (http://www.ximeta.com/web/technology/) use raw Ethernet frames, as they require no tcp/ip configuration, the client finds and authenticates with a code that is different for each device sold, like a network mac address. My pc is on a different segment to the ndas devices that we have, the two segments are linked by a linux box that is doing routing and proxy arp, can

Hello list, I've posted here about this before, but I realise that it may have been assumed that the bridged vlans simply put a switch port in a blocking state and left my question ignored. So to recap. I have two tg3 interfaces named 'in' and 'out' and a bridge named 'br0' My vlan trunk is on the 'in' side of the network, and set as in.2, in.3 ... The

Hello. I''m trying to use vlan in domU, but have something strange: I created bridge on eth0. This interface was configured as trunk with vlan 300, 301. I use this bridge in my domU, and I can see tagged packets when run tcpdump in domU. Also I created interface on domU to work with vlan 300. On this interface I see untagged packets in vlan300. And everything looks fine. But when

Hi, I''ve asked this elsewhere and received hints but no one seems to have a concrete explanation :- What I am looking to do is to be able to configure a Linux based router to be able to share THE SAME SINGLE Public IP address between the linux router and a single computer on the lan acting as the DMZ host (NOT normal NAT IP sharing !). So basically you have a linux router with two

Hi! The Netfilter project proudly presents: libnftnl 1.2.6 libnftnl is a userspace library providing a low-level netlink programming interface (API) to the in-kernel nf_tables subsystem. This library is currently used by nftables. This release includes meta broute support. See ChangeLog that comes attached to this email for more details on the updates. You can download it from:
