i got the following configuration:

Proxyarp vs DNAT
Hello list,
I am in the process of switching from IPCOP to Shorewall s the firewall
for our small office. I very much like the fact that Shorewall runs on
top of the same OS (openSuSE 11.4) that I run on the server and my desktop.
Our setup is fairly straightforward. We have 8 static ip addresses from
our ISP, which provides a cable modem and a Cisco 800 series router.
The ip addresses are

julian''s patches and custom routing
I''m using a 2.6.20-15-ubuntu (shipped with feisty) kernel with
Julian''s patches applied and it''s my 3rd day with tc, ip, ifconfig and
the rest ;).
Got 2 ADSL uplinks. What I need is an ability to manually configure
uplink usage, so nothing like bonding by default. Failover is meant to
be provided via a shell script at the next step. Here is my config:

multiple uplinks works on linux router but not on clients
Hello,
I''m trying to achieve the following.
2 ISP''s and 1 LAN with failover. So, when 1 internet connection fails the other need to take over. I''m aware of the restrictions. The current sessions are lost.
I did this before, one and a half year ago or something. But at that router wasn''t failover. Now i''ve read the nano howto and followed it.

Conntrack, nat and multipath - what is wrong here?
I have a gentoo 2.6.14 box with 4 nics, LAN/DMZ/PUB1/PUB2
LAN and DMZ have a 1918 /22 each, PUB1 and PUB2 have a /29 each of which 5 ips

Using the mangle table, I give all packets a mark (according to local
policies) in the range 1-10. Using ip rule, i pass marks 1-5 through the pub1
route table, and marks 6-10 through the pub2 routing table. Using the nat
table, I SNAT to one

Ip route cache problem

I need some help about a routing problem on a complex configuration.
The problem is that I can''t reach from services outside from my DMZ.
The scenario is a gateway linked to three internet connections, so that
I used three distinct iproute2 tables for routing. The gw is running
