Hi All, I''m a big user of the LARTC document but am currently stuck with a question around section 4.2 (http://lartc.org/howto/lartc.rpdb.multiple-links.html) in relation to "Routing for multiple uplinks/providers". I''m wanting to do a similar setup to the diagram where I have - lets just say for the moment - two uplink providers where I want to route over two

Dear all, I''ve the following problem with routing + NAT: If I''ve two ISP and I''m using two nexthop in default route with MASQUERADE on both ISP links, I see routing cache regenerated, but sometimes packets sent to a new link (after cache regeneration) uses wrong source address for masquerading. Here is the config. I''ve two links to outside via two

Hi there, I am experiencing an annoying but not critical issue with (I think) tinc's internal routing. My setup is this: HostA (local. ConnectTo = HostC) HostB (geographically close. ConnectTo = HostC) HostC (far away. ConnectTo = nothing) Without tinc, pings from HostA to HostB take around 10ms, and from HostA/B to HostC around 200ms. With tinc, pings from HostA to HostB take nearly

Hello. I am trying to get multi paths running, i.e I want to specify 2 paths from a particular node to another. To test this, I am setting up the following scenario: I create 2 tap devices tap0 = 10.1.1.1/32 netmask 255.255.255.0 tap1 = 10.2.2.2/32 netmask 255.255.255.0 I then issue the route command: ip route add 10.3.3.3/32 nexthop via 10.1.1.2 nexthop via 10.2.2.3 The route table

I have question about multipath routing. I am running a 2.6.7 kernel (gentoo). I have a route with three nexthops on the same interface. I see a different nexthop being picked for different destination addresses. All is fine. Now if one of the nexthop goes down (arp entry times out and arp request doesnt get a response), does it remove the nexthop from contention and only use the remaining two

Hi Friends, I am running Centos 5 64-bit on a Dell sever. I am trying to configure iptables for smtp traffic for which I need some help/guidance. The scenario is like this: On a linux box we have 3 public ips(eth1,eth2 and eth3) and 1 LAN IP(eth0). 2 public IPs are from the same service provider and 1 is from different service provider. eth3 and eth2 are from the same public provider but

I have a linux server running Mandrake 10, with the kernel configured with "CONFIG_IP_ADVANCED_ROUTER=y CONFIG_IP_MULTIPLE_TABLES=y CONFIG_IP_ROUTE_MULTIPATH=y" options, with 4 ethernet cards: - 2 ethernet used to connect to my lan (eth0=192.168.1.x and eth1=192.168.2.x) - 2 ethernet used to internet connection (2 adsl lines, both with 600/300 kbtis) The two lan are used to share

Hi I''m trying to monitor my multi ISP shorewall with swping, the script works fine, i can see in log when an ISP is down, the script restart shorewall and /etc/shorewall/isusable is called, however in the swping log after the shorewall restart i see again a route by ISP (even the ISP down), is it normal ? should i not see one route less? shorewall version 4.4.5.4-1. ****

Hi, I have a little problem to setup iproute in my network It looks like this: ---- ----- ------ R1 R2 R3 ---- ----- ------ | | | | | | ------------------------------- ETH1 ETH2 ETH3 ETH0 ETH4 -------------> DMZ ------------------------------ | |

Hi All, I''ve configured a mutlipath as detailed in the HOWTO. For the most part it''s great, but when the cheap DSL line drops it''s connection, as it regularly does, the outbound routing doesn''t automatically use the remaining path for internal outbound traffic. Ip route show lists no default route once the default path dies, and if the ppp connection is

Hello In the LARCT how-to subitem: 4.2.2. Load balancing the following phrase says: "" Instead of choosing one of the two providers as your default route, you now set up the default route to be a multipath route. In the default kernel this will balance routes over the two providers. It is done as follows (once more building on the example in the section on split-access): ip

Hi, I have a problem with my script. I have a debian with a kernel 2.6.8 patched with patch-2.6.8-ja1.diff of nano.txt site. I have 3 internet connections : - eth1 : - ip : 192.168.8.75 - gw : 192.168.8.73 - eth2 : - ip : 192.168.1.200 - gw : 192.168.1.2 - eth3 : - ip : 192.168.2.200 - gw : 192.168.2.1 and my eth0 for

Hello, I''m trying to set up a gateway for a local network to use two dsl lines. Ok, I read the LARTC howto and set up two routing tables and the correct balancing default gw. It works fine for connections originating locally on the gw machine. Then I added two iptables rules on the nat table: iptables -t nat -A POSTROUTING -s 192.168.4.0/24 -o $TI_IF -j SNAT --to-source $TI_IP iptables

Hi, I have a question about the memory dependence analysis. I am trying to use it to selectively enumerate a set of pairs of (load, store) instructions for every function by calling getNonLocalDependency() on the MemoryDependenceAnalysis. This populates a DenseMap<BasicBlock*, Value*>. I just looked up an usage of this in GVN.cpp: MD->getNonLocalDependency(C, deps); for

Hi! In our students'' hostel we have 6 DSL lines (dialups to different providers); we have set up a linux box (currently running 2.6.11-rc2-mm2, but the problem described hereafter also applies to previous 2.6-series kernels) with help from http://lartc.org/howto/lartc.rpdb.multiple-links.html#AEN298 Our Setup looks like this: 10.0.0.0/8 10.70.255.1 +----------+ +-----------+ |

Hello, I have a laptop with two network interfaces: eth0 (LAN) and eth1 (WAVELAN). Now I am looking for a way to route ssh and icpm packages via the wavelan interface and the rest over the LAN interface. My problem is now that every applications binds eth0 interface as default (which results in source addr 192.168.0.2). What I did is using SNAT to change source-address to 192.168.1.2 for packages
