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. /\/\/\/\/\/\/\/\ +----------------------+

Trying to use the policy drop rule with the bridged firewall, when I removed the first line the transparent proxy works great? It seems a bit strange as from reading several articles on it I thought the following occurs. 1st line - if it doest match it gets dropped on the local filter input. 2nd line - redirects the traffic off the link layer into the network layer ready for line 3. 3rd line -

Hi I have been using Shorewall for a while now and find it very useful and easy to configure, I am learning iptables and having trouble getting the bridge to successfully work with squid, although I get it working with Shorewall straight away? Does anyone know the rules to successfully use squid with a transparent bridge? Internet – router - (bridge eth0 – eth1) – local lan auto lo iface lo

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

Hi all, This is my first post to this list. I hope someone can help me, I have been getting grey hairs trying to make this work! I have a bridge setup on a debian sarge box. The bridge is called br0 and sits between my cable modem and a non-name brand router/switch: [cable modem]----[eth1]---[br0]----[eth2]-----[no-name brand router] I have squid setup on the linux box and it works, I have

Hi list, I have the following problem: my boss and some other people on my lan want to use their ISP smtp to send mail when they connect from work lan, but, of course, their ISP smtp don''t allow relay when they aren''t at home. You can image my networks so: eth0 internet public ip eth1 local1 10.88.11.0/24 eth2 local2

Hi, Sorry to bother you all. I have a typical problem sharing DSL upstream bandwidth with users. I have 3 types of traffic high-priority, medium-priority and low priority. My upstream rate is 960kbits. Traffic (any priority) can vary in bandwidth from 0 to 960kbits. I have a test setup where I can pump 600kbit of high priority sustained and I have 400kbit of low priority traffic sustained. I

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

Hello, I am having some routing troubles with my Xen setup. I have two domUs, one running as a firewall and another running as a dmz: The dom0 has the following: - eth0 bridge (10.0.0.3/24) The domU-firewall has the following: - Direct passthrough PCI NIC (Public Internet) - Virtual NIC connected to the eth0 bridge on dom0 (10.0.0.1/24) - Bridge called brdmz for the dmz zone (10.0.2.1/24)

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

Still learning Xen, and would like to know if it''s possible to run Squid in D0 when running in bridging mode. I have iptables and ebtables going, and am able to log packets with those, but can''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

OK one factor that I had not mentioned previously is this is my first time running Debian (yes I managed to do that since 1997...). Yesterday I found /etc/network/interfaces and understood what it does! My system is like the "About My Network" example except that I have 2 class Cs in the DMZ. >From what I understand I use the same IP on the NET and DMZ interfaces. I don''t

Hi Rahul, If you're certain that your problem isn't as Stephen suggested, you might want to have a look at this: --- (From http://ebtables.sourceforge.net/brnf-faq.html <http://ebtables.sourceforge.net/brnf-faq.html> ) How do I let vlan-tagged traffic go through a vlan bridge port and the other traffic through a non-vlan bridge port? Suppose eth0 and eth0.15 are ports of br0.

Hi, First, never compare a linux box with a cheap and dumb broadband router. I''m not sure if i understand very well your scenario but I asume is like this: 192.168.0.1--------- -----------| ipsec | | --------- 128.X.X.X --------- 192.168.0.254 | ISP ----------| linux |------------------| --------- | ---------

Is there a flow diagram as to where tc actions take place with respect to NAT and other iptables functions on a multihomed box (private & public NICs) ? Are tc filter rules consulted before or after NATing? My real interest is in basic understanding first, and then solving a real problem second. Example: Firewall Public NIC 123.123.123.1 Firewall Private NIC 192.168.168.1 Dedicated Video

Hi, I have a suspicious problem with multiple uplinks configuration. First of all my configuration: 1) kernel 2.6.20.3 2) iptables 1.3.7 3) last iproute (for masked marks) All wan interfaces are bridged (stp disabled) in only one interface (wan0), all lan interfaces are bridged (stp enabled) in only one interface (zlan0). The wan0 bridge is to allow UPnP works. To allow related

Hello newsgroup, I hope somebody with more routing experience then me can help me with the problem I have. The setup is as described below. A dual internet provider routing, multiple local area networks, and a dmz network with one public and one private ip range. I followed the instructions at lartc.org, and so far everything is working. The default route is via

Hi, First, some software versions, just to get them out of the way: - CentOS 5.x through Centos 6.2 - Ruby 1.8.5 - 1.8.7 - Puppet 2.7.19 - Facter 1.6.11 Just a note - we''re working from the EPEL repos almost exclusively. I am working with the firewall module, and so far I am unable to use firewallchain. Some digging suggests that it''s not completely user error (though I
