similar to: Multipath Routing..

Hello folks.. Does any of you know if it is possible to rewrite the ip src in a packet. I have a problem involving a DMZ with external IP addresses routed trough a single WAN IP. When the server initiates a connection, it looks like it comes from the WAN ip instead of it''s designated External IP routed through the WAN. So in short, Is it possible to rewrite the packet in the router,

Hello, I have set up a multipath gateway. System is a linux 2.4.29 kernel, iproute 20010824, iptables 1.2.11. here is the setup: firewall:/# ip rule 0: from all lookup local 100: from all lookup main 152: from all fwmark 10 lookup wan1 153: from all fwmark 20 lookup wan2 201: from 213.223.96.121 lookup wan1 202: from 82.236.230.217 lookup wan2 1000: from

Hello. I have the problem that I have two gateways on the same subnet, 80.237.244.1 and 80.237.244.33. Both gateways are 100 MBit cards, so I have 2 times 100 MBit to the Internet. The NIC in the server is a gigabit-card, so this card is easy able to use both gateways for outgoing traffic. Now I just want to use both gateways for my outgoing traffic but no matter what I do, it doesnt work. I

I am developing load balancing router, But I have a question about fail over. The follow diagram is my test environment and scripts. ------------------------------------------------------------------- Environment Setting PC1(192.168.10.2) | (LAN) | PC2-eth2(192.168.10.1) +

Hi all, I''ve a routing problem. I''m setting up a router based on debian (kernel 2.4). I need to setup routing to export an ftp service (ftp server is in dmz) to 2 wan (both). I setup prerouting ad forward rule with no problem. The problem is that reply packet use default gateway (default wan) even though they are enter using the other wan. I solved it marking packets in input

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, I am thinking of connecting a Shorewall Firewall to three different ISPs and load balancing some but not all connections. Just asking for some advice for now. Here''s the network layout: ISP1 ISP2 ISP3 ADSL Router 1 ADSL Router 2 ADSL Router 3 | | | FW:eth0 FW:eth1 FW:eth2

Hi, I have searched the archives on the topic, and it seems that the list gurus favor load balancing to be done in the kernel as opposed to other means. I have been using a home-grown approach, which splits traffic based on `-m statistic --mode random --probability X`, then CONNMARKs the individual connections and the kernel happily routes them. I understand that for > 2 links it will become

Hi Tom (and others) encase you don''t know my network already ;) here''s a quick run down eth0 lan 192.168.1.1/255.255.255.0 eth1 wan1 172.30.7.4/255.255.240.0 eth2 wan2 202.37.230.93/255.255.255.192 eth3 wan3 203.96.213.73/255.255.254.0 I''ve got routes and rules for all the above interfaces :) I want to add another one, however I fear this might cause some issues I have

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

Hi, How do you meter the amount of bandwidth a user has consumed (as webhosting companies do) under linux? I have searched everywhere, but have been unable to find a solution. Apologies if this is the wrong forum.

Hi There is a Centos 7 up-to-date box with 2 interfaces, let's say 192.168.1.12 - enp2s0, 192.168.1.13 on enp3s0. Default gateway on enp2s0. The gateway is pfsense, IP is 192.168.1.1 with 2 WAN connections On the gateway the outgoing traffic is routed by source ip to different WAN, 192.168.1.12 to WAN1 and 192.168.1.13 to WAN2 On the centos box are set all the route and routing rules:

I''ve applied julian''s paches to a 2.6.14 gentoo kernel with the appropiate options enabled, and i''m using a modified version of the mpath2.sh script also available on julian''s site http://www.ssi.bg/~ja/ Overall everything works nearly perfectly. Incomming connections to either the fios (PPPoE) connection, or cable modem get routed back out correctly. The

Hi! This is another thread of "setting gateway in interfaces file" and while i dont want to create any confusion here, i have decided to open a new thread.(which mean Diamond King no longer a subscriber to shorewall-users) Actually, i turned out not to be the MARK issues. Something is missing and i got this error instead :- Setting up Accounting... Creating Interface Chains...

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

We''re trying to figure out how to have equal cost multipath routing using OSPF (quagga) and have come up with the following... Has anyone done something similar? -- How do you deal with incoming services (mail/web/etc) in such a scenario as below - And does anyone have any suggestions? There''s more detail below.... Diagram and overview: Network A connects to Core1 and Core2

Hi all and specially Mr. Tom.... (Please, do not be acid with me please! I am only a newbie, trying learn more about shorewall) I get involved with a Firewall Project in a customer here in my city... In this customer, he has two Internet Providers. So, he ask me how make certain connection following one routing path (like RT_1) and others connections type, following the other routing path

I have tried using iptraf for my NAT firewall to analyse the IP traffic. Basically I am faced with this difficulty of related the source IP to the outgoing interface to the internet, so I am wondering if anyone has a suggestion for a different ways to do it, or a suggestion for a better tool. Details :- Supposed : eth0 - LAN eth1 - WAN1 eth2 - WAN2 And then

Ok here are all the information the website said I should include first: [root@residents root]# shorewall version 1.4.8 [root@residents root]# ip addr show 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 brd 127.255.255.255 scope host lo 2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 100

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:
