Hi all, I have managed to setup a Fedora 7 box with 3 ethernet cards and two ADSL modem/routers from different suppliers as LARTC recommends. I am able to direct traffic for specific internal IPs either to one or the other ADSL line. However, I am faced with two problems I am struggling for the solution: 1. I have opened a few ports on the ADSL router/firewalls to talk to internal hosts; say when

Hi All, With the help of Chuck Tuffli, I'm now able to use CTL to export a zvol over FC to a Linux host: LUN Backend Size (Blocks) BS Serial Number Device ID 0 block 4185915392 512 FBSDZFS001 ORA_ASM_01 lun_type=0 num_threads=14 file=/dev/zvol/tank/oracle_asm_01 1 block 4185915392 512 FBSDZFS002 ORA_ASM_02

Hello, Thanks for the great Shorewall which has replaced my hard to maintain home-made scripts. First, what works. Our local network is 10.48.X.X with multiple vlan, each on a dedicated interface. We use Shorewall 4.4.11 from Debian Squeeze. We have a 2 ISP: - isp1 : an optical fiber provider with 10 Mbps. - isp2 : a DSL provider with 15Mbits/1Mbits. We use isp2 as the default outgoing

I''ve read all the HOWTOs and i''ve reading LARTC messages for a month now. I still don''t have a clue on how to do it ''cause sometimes people say

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

I''ve just started to recently look at CBQ and HTB, but I''ve been wondering whether or not something like the following is possible: I''ve got two external links: +--+ | |-----ISP1 |FW| | |-----ISP2 +--+ One link has a bandwidth cap, and the other doesn''t. What I want to do is, punt all outbound traffic out via ISP1

Been running this for quite a while and noticed that have intermittent problems getting out. Find that if I ping the same site from 2 computers it may work on one and fail on the other. Also was surprised that some time they are going out different interfaces at the same time. Seems to work all the time from the firewall. Running 2.6.10 kernel with the multipath routing patches on a debian

Hi, this might be a dumb question, but I''m not finding much information online. I''m trying to setup a 2.6 linux box to run nat across multiple upstream links as a simple way to aggregate bandwidth. I found the instructions in lartc section 4.2 (http://lartc.org/howto/lartc.rpdb.multiple-links.html) fairly clear and straightforward. I implemented those, and a couple of trivial

Hi there. Currently, our network design has two ISP lines and 3 subnets for LAN. Below are some details :- eth0 - isp1 eth1 - isp2 eth2 - subnet1 eth3 - subnet2 eth4 - subnet3 What i wanted to do is to assign incoming port 80 to our local squid server running on the firewall itself and assigned it to eth0(ISP1). I think it shouldnt be a problem as /etc/shorewall/rules provides a sample of the

Hello! I have set up a LINUX router with two seperate uplinks to do load balancing. I made all the configuration after the "NANO-HOWTO to use more than one independent Internet connection" document. I patched my 2.4.24 kernel with patches, described in this document. My configuration is: --------------------------------------------------------------- #!/bin/bash

Yes, this is a dumb question. I haven''t the time nor the resources to dig into the guts of this right now, so perhaps someone will take a few minutes to help, please. I just implemented a classic "nano" multipath setup. The script is at http://yesican.chsoft.biz/lartc/rc.nano1 What I need to know is if I need SNAT in the firewall when a packet comes in on the

Hi, I''m using Shorewall and LSM to load-balance 3 ISPs. My configuration works, but when an ISP is disabled, LSM is unable to ping from the associated interface. I understand why it happens : when `shorewall disable isp1` is called, Shorewall flushes the routing table isp1, and removes the nexthop in the balance table. So when I want to ping 8.8.8.8 from eth1, no rule allows it.

hello, i have 2 links to the ISP of 128kbit each, and i want to balance the trafic between them, but not staticly (local ip1-5 throw isp1, and the rest to isp2). I though at a ingress clasification, then routing by the mark, and at the exit nat (yes i must do nat :(((, but the clasification must be flow based, and i dont know how to do it.
