similar to: the routing cache and route selection; is this correct?

Hello all, I am going through the LARTC howto to understand how the iproute2 works. But some concepts like Policy Routing, RPDB etc are not clear to me. I am pretty new to iproute, beeing using route command for long... From what I understand 1. rules (ip rule) tell how to select packets for routing and route (ip route) tell where to route the selected packets. 2. A collection of rules is

Hello all, I need a virtual firewall/router solution. I''m thinking of a netscreen 1000 but I want to know if it can be done in Linux. Here is my idea: 1 Linux box 2 GigE interfaces 1 interface setup with a public IP address ($PUBIP) 1 interface setup with 802.1q VLAN trunking with 100 vlans assigned ($VLAN1-$VLAN100) a /25 subnet routed to $PUBIP from my core routers All $VLAN

Assuming if I have rules matching the same packet, the one chosen is the lower preference value or the high ? For example # ip rule list .... 100 from 192.168.1.0/24 lookup main 200 from all fwmark 5 lookup first ..... Packet is matching both rules, the one with priority/preference 100 or 200 is selected ? _______________________________________________ LARTC mailing list /

Hello all, I am working with kernel 2.2.20 with the necessary options configured into the kernel to support all of the wonderfully fancy routing features: - routing based on ToS - routing based on fwmark - multiple routing tables This same kernel is in use elsewhere, and is routing based on fwmark with success. This leads me to believe that my kernel is OK and that I have another

Hi all! I try to make port based routing, because a have two connections to the internet. My router is a "one disk floppy router for linux". It is a big router project www.fli4l.de. I try also to make a opt, it is like a plugin for this router. This project uses Kernel 2.2.19 compiled with libc5 (because it is small and you can use one floppy disk). At the moment, iproute2 is not

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

Hello, everyone! I would like to solve the following problem. Btw, I''m terribly sorry about the pseudo-asciiart, but that''s all I can paint as a tropology. I''m hoping it''ll be enough. ----Internet---- | | | eth0 machine A routing+ipchains eth1 | ------------------ machine B So, given I''m running kernel 2.4.19 and using ipchains

I''m having trouble routing on high fwmarks, I want to use a lot of different marks for 2 routes so that I can QoS based on the marks ip rule looks like this: 0: from all lookup local 32751: from all fwmark 31 lookup dslout 32752: from all fwmark 30 lookup dslout 32753: from all fwmark 29 lookup dslout 32754: from all fwmark 28 lookup dslout 32755: from

HI All , I am running a FC6 box with two internet links with load balance . Every thing is working fine expect the MSN connection that failed and reconnect every time and SSL connections . I would link to know if with the nona howto I could fix that . I have been tried with no success to redirect that connection only to one link but its look like do not work . Here my configuration :

hi I have trying to remove the extra rules from my routing tables, however with no luck Also I want to know these duplicate entries have an effect on packets going routed? I have this overwhelming rules lists from my predessor who added the "ip rule add fwmark" entries in firewall script, and on each run of firewall script its creates an extra entry in routing table. Now what I want to

hi thanks for your reply heh "Example: ip del rule pref 32742" is syntically wrong :) and when i tried "ip rule del 32742" it gives me error # ip rule del 32742 Error: argument "32742" is wrong: Failed to parse rule type so how to get get of these extra rules? 0: from all lookup local 32742: from all fwmark 0x2 lookup squid.out 32743: from all fwmark 0x2

I configured multiple isp (actually only multiple gw) according http://lartc.org/howto/lartc.rpdb.multiple-links.html. Now NAT (Internet) seems to work, both external interfaces work ( I didnt configure load balancing because I dont need it). However I have problem that I can not ping from NAT to public ip of my Linux box. Problem is that I can not connect from 192.168.1.0/24 network to services

Here''s my situation: I''ve got an Intel machine running a 2.6.9 linux kernel and this box has 4 modems attached to it via a usb to serial port expander. In order to force data down each of the modems, some pretty simple rules are used and they are as follows: iptables -t mangle -A OUTPUT -p tcp --dport $PORT1 -j MARK --set-mark 1 iptables -t mangle -A OUTPUT -p tcp --dport

I set up this config: +------+ -+ ISP1 +--+ +------+ | +-------+ +--+ linux | +------+ | +-------+ -+ ISP2 +--+ +------+ No problem. Standard setup with two ISP''s. Both routed subnets. Default gateway is ISP1. No magic here. Now I put a server behind the Linux box. I want the server to be reachable on an /extra/ IP in the routed subnet of ISP2. +------+ -+ ISP1

Hi list, I''m new to this list, I just subscribed because I have some ackward about IPRoute2. First, while playing with NetFilter'' "MARK" target, I met a weird behaviour once I tried to use this marks in the RPDB : the packets where successfully marked, but it seemed that RPDB didn''t succed in matching them (for those who already know the answer, I only used

ok i will do it in text: 66.92.114.46 eth0 209.141.2.194 eth1 192.168.119.101 eth2 192.168.120.101 eth3 What i have is a linux box RH7.3 which will eventually run Shorewall Firewall. On this box there is eth0 66.92.114.46 conneted to isp1 and eth1 209.141.2.194 connected to isp2 It also has eth2 192.168.119.101 and eth3 192.168.120.101 which will connect to a failover appliance which has 2 wan

Hello all, I''m using iproute2 + ipchains and have a question about locally generated packets. I have noticed that I have no problem marking packets in the input chain from sources other than my router. These packets are marked and routed exactly as I expect. Now supposing I want to mark particular outbound packets which are locally generated. The only solution I have found so far
