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

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) +

Hello all, I need a very simple routing protocol for VPN redundancy. We have several sites and each site has a Linux router and two IPCops each with an ADSL connection to the internet using different ISP''s. I have configured VPN''s between all of the sites for each IPcop on ispA and the same for the IPCops on ispB. This way, if one of the ISP fails, I change the route on the

Hi list, I have a problem I thought was simple first, but now I''m stuck. In a nutshell, it''s about redundant uplinks at an outside location. Crude ASCII-Art follows: Internet | | +------------+ | cisco with | | uplinks | +------------+ | | ATM interface +----------+ ... | alvarion | | | wireless

Hello all! I applied http://www.ssi.bg/~ja/routes-2.6.8-10.diff patch to kernel 2.6.8.1 and it works fine, or almost fine. It does the load balancing well, but when one link is dropped it continues to try it. At the end of http://www.ssi.bg/~ja/nano.txt it is said to ping gateway 1 and gateway 2, for the kernel to know if that route is working, but since my linux is connected to the links

Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

I''m a little confused about the many ways I''ve read that can be used for traffic load balancing, that is, two or more interfaces to the outside world being used transparently and efficiently by the internal machines. I heard about: a) netfilter SNAT to more than one IP. If I''m correct, this is only a round robin, that is, one connection goes here, the other goes there,

Hi Guys, I would just like to have advice and pointers of the best way would be, Someting like BGP or OSPF? I have 2 internet connections at diffrent locations. let say connection A and B 1.) router A has a fast internet connection and a seperate interface for clients using /lan/pppoe/ipsec etc and another ethernet interface going to router B 2.) router B has similiar setup as router A and

I am setting up 2 Vyatta routers that will serve as redundant failover core routers out to the backbone of our ISP. They will be serving for routing between other branches and the ISP and bandwidth management. I am trying to differentiate between the plethora of information about having redundant, automatic failover routers and pretty much decided on VRRP for the IP address failover mechanism. I

hi all, first i wann to explain my network & it''s problem, i am using a redhat el5 for multigateway routing, i have 3 adsl lines which is connected with eth0, eth2 and eth3. eth1 is my local network. those 3 lines comes with adsl modem from same isp with equal bandwidth (512 Kbps). In this adsl modems there is one lan and one wan port, adsl modem''s lan ip is gateway for my

I''ve recently got a new modem. In fact, it''s a modem-router with NAT functionality. Before I had a plain modem-modem, and I was able to access my workstation from my remote server using the IP address assigned to me by my ISP. Now however, that IP address only reaches the modem-router and the IP address of my workstation is set by my modem-router to 192.168.0.2 How can I

Hello all: I''ve read the documentation and am not quite sure where to start. What I''m trying to do is build a network with a 3 NIC Shorewall router. My system is behind a routed /49 network. I''d like to use 2 or 3 of the static IP addresses for my DMZ ( DNS server, mail, webserver etc ) and then have my remaining machines in a private network NATed is some way. My

Greetings List Members, I''ll firstly apologise if this isn''t the place that I should be posting this message but here goes. What I want to do is have a VPN (PPTP/IPSEC/CIPE/etc) server, but it must support more than one simultaneous connection. I currently have a PPTP VPN server setup that has port 1723 and protocol 47 DNAT''d through to the internal IP

Not normally a question for this group, but you guys are very bridge/router/firewall savvy, so I thought I''d toss it here. I have a bridge. On one side of the bridge is that fancy thing called the Internet. On the other side is my LAN. The bridge is the obvious demarcation line and a good place to put a firewall. Now, I have all my iptables stuff planned out, EXCEPT for nat. The

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel

Hi There, we only have a /29 internet routable network from our ISP and a Cisco 1601 router with serial interface doing all the routing. I was thinking of replacing that cisco with a linux box with a sangoma card, also using quagga with ospf on for my internel networks has anyone have expierence with this? thanks Sew

Hi all! After that good thread "DGD patch not detecting dead gateway" I was able to set up a Load Balancing with ping based DGD (without Julian Anastasov patch). But now I''m facing a new problem and tried some options, with only partial solutions. I made a script based on http://www.mail-archive.com/lartc@mailman.ds9a.nl/msg16257.html (Thank you Manish Kathuria),

I hope this list is still active. I''m an experienced Linux Sysadmin, but I haven''t done much in the way of routing. Due to a decision made by my higherups, I need to jam a computer between my ISP and my LAN to do bandwidth throttling. My current setup: 1 Crappy Cable Modem (7Mb/768Kb connection) with a static IP. 4 servers (all have static, routable IPs) - One of which is

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
