Hi, Apologies for the cross-posting; I''m not sure whether this is a firewall or routing issue, or both! I have four network cards, detailed below. eth0 and eth3 connect to my ISPs, and eth1 and eth2 connect to local networks. I want to route all traffic from eth2 to eth0, and from eth1 to eth3. However, I am having a few problems with this. eth0 ip: 192.168.100.253/24 gw:

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

Hi, I am trying to set up a linux box to act as a router for my college. There are two different types of users; students and conference guests, and they have IPs statically assigned by DHCP, from separate ranges (but they are on the same subnet). The students go out onto an academic connection (via eth0), and conference guests go out on an ADSL line (via eth3). eth1 and eth2 are configured for

Hi, I have a linux router with 4 ethernet cards; eth0 through eth3. Basically, all I want to do is route all traffic from eth2 to eth0, and all traffic from eth1 to eth3. I''ve looked through the LARTC how-to, specifically at chapter 4, about multiple providers. However, I am still a bit confused, and not sure how to set up my routing tables, as my scenario differs from the one in the

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 are being

Hi, I am new in LARTC list. I had intermediate skills in networking. What I tried to do: Use 2 links with loadsharing + falt toletant (to add bandwitdh) ok ! I am use Debian Etch in router/fw With kernel debian default + routes-2.6.17-12.diff patch The Problem: The iproute2 just route thought the last gateway of nexthop rule. I was running tcpdump in 2 terminals, tcpdump -nni eth0 ...

Which files do I need to edit in order to initialize a route after a reboot. I have a 802.1q tagged VLAN interface which I need to create a rule, and a route for. I see on my CentOs 4.2 box that in /etc/iproute2 there are the following files. I realize that I can add my tables to /etc/iproute2/rt_tables, but when I want to create a rule I am not sure where to put the information for the

First of all, thanks to this group for the awesome documentation on the load balancing and thanks to http://www.ssi.bg/~ja/nano.txt. I''m now balancing a DSL and Cable Modem account (DSL is 1.5/768 and Cable is 3/256). It took some work but I learned a lot along the way. For a few sites that I tend to download a lot from, I found that I could configure Flashget

I''m using Debian (sarge) I do now have 2 ISP, one DSL and one cabel. I want to use the DSL as my primary and only use the cabel-modem if the DSL fails. The setup is: IP1 -> Router -> NAT_IP1 -> eth0 -> eth2 (LAN) IP2 -> Cable-Modem -> eth1 -> eth2 (LAN) I wrote the following in my /etc/iproute2/rt_tables ip rule add from NAT_IP1 lookup 1 ip route add

Dear all, I am having problem using iproute2 on my new Slackware 10.1 box. Here goes the problem: root@localhost:~# echo "200 DOONET" >> /etc/iproute2/rt_tables root@localhost:~# cat /etc/iproute2/rt_tables # # reserved values # 255 local 254 main 253 default 0 unspec # # local # #1 inr.ruhep 200 DOONET root@localhost:~# ip rule add from 10.255.255.0/24

Hi guys, I have a question about of route-map with linux, I have two routers linux, one for Internet Trafic and other for VPN traffic, both routers have public IP''s address. Internet with nat VPN with nat eth0 200.244.10.1 eth0 200.244.10.2 ---- ----

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? -------------------------------------- # cat /etc/fedora-release Fedora Core release 2 (Tettnang) # uname -r 2.6.5-1.358 #

I've managed to configure a LVS Cluster to act as a transparent proxy squid farm, with a virtual server as load balancer, and three real servers. Because redirecting packets going to port 80 to port 3128 of squid in the load balancer doesn't works, the solution has a mix of ip route and iptables. Here is the script I wrote to configure transparent proxy. #!/bin/bash #Transparent proxy

Hello, I have a routing configuration that I''ve been working on and seems to be working well for me. I''d like to ask for some peer review. If your interested and can take a moment to consider this I could use some advice on if this correct. I''m still very much learning, sorry if this email is off topic or too long or anything. I want to route a wireless network

Hi, I think you now have 2 Links to the internet. You want to route web traffic (transparent proxy triffic) via one link and the rest via the other link. If it is the case, It is possible to do. I have done it. here I have mentioned eth0 and eth1 eth0 is connected to one link (link1) eth1 is connected to other link (link2) , via this link, web traffic will be routed. echo 210 link1 >>

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.

Hi All, I am hoping someone can help me with a project I am doing at work. I warn you in advance that this will be a long post, but I wanted to provide as much information as I could to explain what was going on. Any help would be very much appreciated and welcomed as my boss would like to see this up and running this week. I have been scouring various documents on advanced routing for a

Hi, my box is connected to 3 networks, eth0 eth1 wlan0. I want "my" traffic to go via wlan0 and everything from eth1 NATed to eth0: eth0 192.168.1.10/24 eth1 172.16.1.1/12 wlan0 192.168.10.190/24 I first tried this with two single hosts: iptables -A POSTROUTING -j MASQUERADE -o eth0 -t nat iptables -A POSTROUTING -j MASQUERADE -o wlan0 -t nat echo 200 Forw >>

Can I add routes to rt_tables by hand with the vi editor? If I add a route to that file, it will be there if I reboot the box? I am sure there are stupid questions but I can''t find the answer into the papers I have here. Luis Miguel Cruz Miranda.
