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 RPDB 3. Policy routing is ro...

I have two adsl lines on my linux firewall box and i want to do some load balance between them...i tried a lot of different things, but it isn´t working...Following the instructions of http://lartc.org/howto/lartc.rpdb.multiple-links.html i used the configuration above. using "iptraf" I can see some few packets using the ppp1 connection, but almost all the packets use ppp0 connection. I´m doing something wrong? I´m forgetting something? Maybe my kernel doesn´t support multipath? how can i check it? I us...

...e address + type of service (tos) + fwmark (fwmark) + interface on which packet was received (iif) - If a routing cache entry exists, we''re done: the route has been selected. - If there is no routing cache entry, we continue with route selection by consulting the RPDB and routing tables. 1 start traversing the RPDB at the highest priority 2 keep traversing the RPDB for the next matching entry 3 when a match is found, try to find a match for the destination in the designated table 4 if there is no matching route in the specified routing tab...

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

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

...sing via interface eth0, regardless on what socket used to send it . QUESTION: How can I configure my routing in such way that outgoing traffic always exit the host by interface associated with transmitting socket ? ( I hear a little about source routing and ideas from http://lartc.org/howto/lartc.rpdb.html#LARTC.RPDB.SIMPLE are helping, but I don''t like idea to run "ip rule add from" each time my IP changed). I''m looking to some simple way to instruct routing engine to forward packets via associated interfaces. Regards Stas

I need to route: from 196.33.50.0/25 (default route) to ISP1 from 196.33.248.0/24 (default route) to ISP2 ISP1 --------- fire --+---- 196.33.248.0/24 / | ISP2 --------/ +---- router ----- router ----- 196.33.50.0/25 What I''ve done: Default route via ISP1 created routing table ISP2 for default route via ISP2 I would like to do the following but they get

hello list (and martin) ;x i have now composed my final(?) policy routing design. the goals i had when beginning with this, for you that have not follow mine and martins thread, was to 1) only let 192.168.1/24 to see all routes, 2) not route between defined networks, except to and from 192.168.1/24 and 3) not defined networks should only be able to reach 192.168.1/24. this might sound simple.

...with three NIC''s, I have used brctl tool to configure this box as a bridge, i have given it ONE logical ipaddres, Every thing is working fine, but now i am required to configure the same bridge as a LOAD BALANCER.... On some googling i found the following link http://lartc.org/howto/lartc.rpdb.multiple-links.html This HOWTO requires me to have one ip address for each NIC, while i dont in my case... Now, is BRIDGING+LOAD BALANCING possibe on the same machine??? Any sort of inputs regarding the matter is most welcome Thanx in advance KARTHEEK Yahoo! India Matrimony: Find your life par...

...I''ve got it autoconnecting on startup and redhat puts ppp1 as the default gateway, this is then setup for masquerading for the entire network. Therefore I''ve tried setting up ppp0 as the deafult gateway for only one computer (10.0.0.11), as it says at http://lartc.org/howto/lartc.rpdb.html#LARTC.RPDB.SIMPLE I''ve done everything it says there and im 99% sure I''ve put the right ip addreses in etc. When Ive gone through it that computer is no longer able to access the net (the rest of the network is unaffected). I''m pretty sure its the way ppp0 is confi...

Hi, Is it possible to create a routing rule that depends on the source host/network, besides the target host/network? E.g. route everything from 192.168.0.x to 10.0.0.1, and route everything from 192.168.1.x to 10.0.0.1. TIA -- Groeten, Joost Kraaijeveld Askesis B.V.

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 servi...

I have two T1s and I'd like to split my SIP traffic over the two. I am looking at this: http://lartc.org/howto/lartc.rpdb.multiple-links.html what bothers me about it is the note "Note that balancing will not be perfect, as it is route based, and routes are cached. This means that routes to often-used sites will always be over the same provider.". If all my traffic goes to the same IP, which is a remote SER...

Hi, I have a server with 2 NIC and 2 different ISP. The idea is configure a Load Balance with these 2 providers. I reviewed: http://lartc.org/lartc.html#LARTC.RPDB.MULTIPLE-LINKS but I would like to know if this is a good method to use with CentOS 6. Thanks in advance!

Can someone refer me to any links which explain how to configure a stand alone linux host (not a router) with 2 ISP links in such a way that the traffic is distributed between the 2 ISPs ?

I have two ISP links that I am trying to firewall through a Linux Server, I have been following http://lartc.org/howto/lartc.rpdb.multiple-links.html and I can not seem to get it working. Do you have to NAT the incoming packets for this to work correctly?

.... Let me explain: I have eth0 interface to which I set 2 IP addresses; 192.168.0.1 and 192.168.0.2. Then I want to connect to Internet through 192.168.0.254 gateway using round-robin between those 2 addresses. The iproute2 usage that best fits my needs is following: http://lartc.org/howto/lartc.rpdb.multiple-links.html But I was unable to get it working, as it supposes I have 2 *interfaces* while I have only 1 interface with aliases. I''m simply unable to set the same gateway on both IPs as it seems to be per-device setting. I am aware that iptables is able to do it with: iptables...

Hi all, I have two internet connections, both connected to eth0 and eth1, one is 1mbit, the other one is 3mbit. Now I want to use _both_ at one time via round robin or such. Anyone have an idea/docu how to set that up?
