similar to: SIP, NAT, and load balancing problems

Maybe a strange request, I''ll try to explain this as clearer as I can (forgive my bad english, please :-) ). I''m setting a linux box as a router. My router uses multiple routing tables, so I can address the traffic from specific ip addresses of my lan to distinct ISPs providers (specifying a different default gateway fo r each table), marking packets with iptables

Hi, I have the following config: 1 PC with 3 NICs, that shares internet connection to LAN. eth0 uses a public IP ($public_ip_1) eth1 uses a private IP ($private_ip) eth2 uses a public IP ($public_ip_2) I have a webserver and a mailserver accesible by $public_ip_1 (eth0) I have a LAN with all terminals using private IPs, and $private_ip (eth1) as gateway. $public_ip_1 and $public_ip_2 are from

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a linux system with 4 ethernet interfaces, eth0 goes to the internet, eth1, eth2, and eth3 are NAT''d LANs. I want to use an ingress filter to prioritize bandwidth (downstream from internet) to various IPs. I want to sett it up something like this.... eth0 <--[NAT]--> dummy0 <---> dummy1 <---> eth1,eth2,eth3 dummy1

hi all, i am setting up a load balancing netwrok with failover, i have applied julian patch, but whenever i try to traceroute from any client node, it gives me two entries for that destination, but i get different interface for that entries, so it doesn''t forward my requests, i have done masquerading for client nodes, the ip rule/route are as follows, ip rule add prio 222 table

Hi, I''ve asked this elsewhere and received hints but no one seems to have a concrete explanation :- What I am looking to do is to be able to configure a Linux based router to be able to share THE SAME SINGLE Public IP address between the linux router and a single computer on the lan acting as the DMZ host (NOT normal NAT IP sharing !). So basically you have a linux router with two

Hi, I have a linux box which balances load between two interfaces ( say WAN1 and WAN2). I have masquerading on for any request coming from LAN to the outside world. The setup is in such a way that WAN1 drops packets with source ip belonging to WAN2''s network and viceversa. For some strange reason, I find that packet coming out from the WAN interface has source address of WAN2 and

Hello people: I''m new in the forum. I''ve implemented the script for load balancing of "Linux Advanced Routing & Traffic Control HowTo" and I''ve a question: When I run the next command : "ip route" I get the folowing information: -------------- 192.168.0.32/27 dev eth0 proto kernel scope link src 192.168.0.33 192.168.0.96/27 dev eth2 proto

Hi there. I''ve two Internet connections at the same box, one connection is made through ADSL, and another is made with a Radio-Link (WaveLAN IE822). I wan''t to do a backup connection with the ADSL link. With what tools I can do this? ipchains, iptables, a third party tool? -- ____________________________________________________________ PIII 500MHz - 98MB RAM -

I have 3 nics in a NATed gateway file server. Two nics (eth1, eth2) provide dhcp and nfs services to an internal subnet via a dedicated switch. The other nic (eth0) connects to an external WAN switch to provide net access to the systems in the subnet. --- eth1 WAN switch eth0 --- | SUBNET switch --- eth2 Question: Is it

On this box there is eth0 66.92.114.46 conneted to isp1 and eth1 209.141.2.194 connected to isp2 It also has eth2 192.168.119.101 and eth3 192.168.120.101 which will connect to a failover appliance which has 2 wan

I recompiled yet 2.6.19.1 kernel (using iptables with the same patches too). The configuration for this test is: 1) linux box with 2.6.19.1 kernel (SMP machine) with these patches/modules: a) l7-filter b) ipp2p c) connlimit d) set 2) 4 ethernet interfaces: a) 2 external (eth1 and eth3) interfaces with balanced links (as described in nato-howto) bridged as wan0

Hi, I''ve been implementing a load balancing solution using CONNMARK, based on solution described by Luciano Ruete at [1]. Gracias por el post y por apuntar en la dirección correcta Luciano! Once implemented, I''ve found that due to some reason packets aren''t properly marked (or improperly remarked) and sent out using the wrong interface. My topo setup is:

Hi There, We currently using iproute2 for load balancing. However we need more upload speed as we load balance over 3 dsl lines. I''ve been looking for a way to combine the upload speed to more faster. Found a site called www.upstreaminter.net where these guys bond the adsl channels to improve uploads, Since downloading is problem as its need to know the ip address of the downloader they

Hi guys, Can you take a look at this? :) +-----------+ | | eth1-|- | | -|-eth0---LAN--- | | eth2-|- | | | +-----------+ - eth0 is connected to the LAN having the IP=LAN_IP eth1 is connected to the first ISP having IP=ISP_IP_1 and GW=ISP_GW_1 eth2 is connected to the second ISP having IP=ISP_IP_2 and GW=ISP_GW_2 I need

Hi, I am connected to two DSL providers (DSL 1 - 1Mbps downlink/384kbps uplink and DSL 2 - 2Mbps downlink/512kpbs uplink) I would like to only allow ftp, pop3 and http via the DSL 1 and only smtp, ipsec and pptp via DSL 2. How can I do so? Can I use iproute to route these protocols? Below is my ip routing: - # DSL 1 ip route add 2.2.2.208/30 dev eth0 src 2.2.2.210 table 1 ip route add

Greeting all, I have a bit of a complicated question. I have two ethernet devices, eth1 and eth2. eth1 is where my internet comes from. It is in the form of 202.172.122.208/29. It has another IP range, 202.172.122.72/29. What I want to be able to do is route 202.172.122.72/29 to eth2, so that other machines can use those IPs, any ideas on how to do this, I cannot work out how to do this.

Hi all, I have a similar question like many asked before I know but Please help as i cant figure out where the problem is and how should I tackle. I have 2 ISP connections. I want to share the bandwidth from both. I have copied the script from many places and created my own after changes. Problem is that only one connection is utilized at a time. Not both working. ratio of consuming

Hi guys; I''m sure you are all bored of hearing the same story over and over... but here it comes again. :) Yep, tomorrow I''m getting another ADSL line installed and I wanted my linux router to handle both providers (new and old). I have my linux router (fedora core 2) setup to do NAT for my current line, but I know I''ll need to change my configuration to
