Routing - new table
Hello,
I have tested a simple thing in two version of Linux and there was a
problem when I have used fwmark as a selector for rule lookups. As you
can see below on the Slack, the <test> table doesn''t have any label
about fwmark. Is there an iproute problem?

multiple kernel routing tables & sendmsg
Hi all,
I have a question about the Linux kernel/IP stack support for multiple routing tables (or FIBs) that I am hoping someone can answer.
This support is also used by the iproute2 package that is available. My question is:
For applications sending raw packets, is it possible to specify the routing table to use when sending? Currently, I am finding that calls to sendmsg() use the main

Using DSCP to choose a route table
Hello,
I am writing a routing daemon that is able to assign different gateways to
a destination address for different classes of service. Multiple DiffServ
Code Point values are mapped into a single class of service. I have
accomplished this by using the iptables MARK target to label each packet
with a class of service value and then using ''ip rule add fwmark'' to have

Routing for multiple interfaces (marking ports)
Hello guys,
I am still in doubt about this kind of server. So my question is about
the "prio" at routing tables like:
I have 3 tables in /etc/iproute2/rt_tables:
201 201
202 202
222 222
In table 201 there is the rules about my internet link (frame relay)
that comes into eth0. So I made this route into it:
[root@ns2 iproute2]# ip route show table 201

--set-mark policy routing problem
In its current configuration one of our Linux boxes has 2 DSL modems
that connect to the same service provider. On the router packets coming
in from the network destined for the internet are marked alternating
using nth match those packets are supposed to be picked up by iproute2
and routed out the physical connections based on that mark, thereby
doubling the outbound bandwidth. The problem is

iproute2 custom tables and rules the CentOS way...
Hi all;
I have a custom iproute2 table and a few rules to go along with it
(CentOS 5) -- I have added the table to /etc/iproute2/rt_tables.
if-up and friends doesn't seem to handle this real gracefully. How are
those of you out there doing something similar managing this
customization?
I don't really want to muck with /etc/init.d/network or the if-up
scripts to avoid breaking upgrades.

routing question
Hi,
How do I configure my routing file to handle the following condition:
www.my-domain.com --> "Web site under construction" page
www.my-domain.com/beta/ --> The actual beta application
In the normal case when I access "www.my-domain.com/beta/" the application
works fine but the redirects go the root and fails. How can I make sure the

iproute2/nano-howto: dual external routing, a "virtual subnet"
A site I administer has dual T1''s. We have this set up according to
NANO-HOWTO[1] using Julian''s routes patch on a late model 2.4 kernel.
All is well, has been working well for a long time.
Recently one of our T1 providers went belly up and we got something
better. Now we have a /28 where previously we only used one IP per
interface.
Present interfaces:

How to create static routes on startup with CentOS4?
Hi,
I'm working with the iproute2/iptables toolset on my CentOS4 server to
create custom routing rules. However, I'm a bit at a loss how to create
these permanently so that they are automatically reloaded upon reboot of the
server.
I know that iptables has a config file in /etc/sysconfig/iptables that is
loaded by /etc/init.d/iptables startup script.
Is there anything that works

Linking two tables using a lookup table

How do I associate two different tables which have a lookup id (table)
as common.
I tried the has_many :table2, :through => look_up_table in my table1

Routing by interface as opposed to ip address?
Hello all,
Does anyone know of a methodology to build a route based on the inbound
and outbound interfaces as opposed to ip addresses? We are essentially
trying to forward packets from one interface to another without looking
at the ip address. Bridging (brctl, br2684ctl) will not work in this
case as the interfaces use different layer 2 encapsulation (e.g.,
atm0<=>eth0, or

Can I do this?
Hello, LARTC!
I''ve been having troubles with load balance with ip + fwmark. I was
wondering if these points are mandatory for this scheme to work:
1. Is there any problem if the linux gateway has a default gateway? Do
I have to remove it?
2. In the scenario with 4 NICs, one routing table each, and another
routing table doing load balance, Do the tables that imply routes that

Simple routing configuration
Hi,
I have a simple question (well, at least I think it''s simple!). I have a
router, with four Ethernet cards; eth0-eth3. eth0 and eth3 are the
''external'' cards, connecting to my ISPs. eth1 and eth2 are connected to my
internal networks. What I want to do is basically filter all the traffic
from one card to another, in this configuration:
eth1 to eth3
eth2 to eth0
