Hi, I have the following setup. Two linux systems with two [test] external interfaces encrypted with ipsec [transport]. Two gre tunnels that pass 10.200.0.0/24 and 10.200.1.0/24 network traffic. Testing the balanced tunnels I would setup iptraf on one and ping from the other. The results would be as expected; traffic would be split between the two interfaces. Testing with an ftp transfer of

Hi , I am trying to set up a GRE tunnel between two linux routers. The routers have a 400 MHz Processor.

Hi All: Ok, here is my network: 192.168.1.0/28 is the network behind the Cisco, the Gig0/1 interface is 192.168.1.1. Linux box is 192.168.1.96/28 behind with 192.168.1.97 the Eth1 interface. I have the Ipsec tunnel up and working between them using preshared keys. So that works. Here is the Cisco tunnel setup: interface Tunnel6 ip address 192.168.2.110 255.255.255.240 tunnel source

Hello, I''ve set up a GRE tunnel between two Linux boxes and it''s working well, with or without IPSEC (under GRE). The problem is that when I have no traffic for some minutes, side A cannot communicate to side B any more, unless side B tries to communidate to side A. The same thing happens in the other direction. For example, side A pings side B. No reply. Keep pinging. Side B

I am attempting to setup an IPSec protected GRE tunnel with a Cisco router. I believe the IPSec association is up, however I cannot move traffic over the tunnel. It is not clear how to integrate the tunnel interface (gre1) with firewall-cmd; adding the interface to trusted does not appear to 'stick'. [root at aqueduct ~]# firewall-cmd --add-interface=gre1 --zone=trusted The interface

Hi! I read http://mailman.ds9a.nl/pipermail/lartc/2002q4/006244.html and I did that. Can anyone tell me if there is something else to do for shapeing over tunnels to work? I noticed that gre interfaces don''t have a queue attached. I''m running linux-2.6.15 and iptables-1.3.4 with no patches. Thank you in advance, Sorin.

Hello Lartc Mailing List: Been working on something the last week and a half and ALMOST have it working.., just need a few pointers from the wizards on this mailing list to nail it. Ok, my setup is a hub and spoke arrangement, hub is Cisco 2821 with IOS 12.4. Spokes are ruggencom RX1000 routers, Debian based with the following versions installed: rx1000test:~# uname -a Linux rx1000test

Hi everybody, I want to do the following setup : | | Tun1 - Link 1 | Tun1 | | Router A | teql | INTERNET Link - | | teql |router B | | Tun2 - Link 2 | Tun2 | | This should permit to agregate Link 1 and Link 2 (less the cost of the encapsulation). The two tunnels are GRE ip tunnel. It seems to work fine

Hi! I want to add to my previous post that: my setup looks like this internet --> linux router with NAT and tc ==> gre tunnel ==> forwarding router --> LAN At my NATting router I can "see" the forwarded LAN (192.168.2.0/24). Now let''s say that there is a LAN workstation with the IP 192.168.2.18 and I filter the traffic with tc for it. If the fowarding router has

Hi! Can I create the unnumbered GRE tunnel with iproute2 utility? Can someone provide me a link/howto/example_config how to do it? The topology is one tunnel between two linux boxes: -- eth1-|__|-eth0 <-------------> eth0-|__|-eth1 -- I''m trying now with: ip tu add tun1 mode gre local loc.IP remote rem.IP ttl 255 dev eth0 ip addr add tun1 0.0.0.0 ip link set tun1 up but it

Hi All: I have a strange problem that was described in a previous mail but I have stripped the problem down to the following: I have a debian based router that I have setup IPSec with GRE over top. The tunnel addresses are 192.168.2.97 locally, the other side is 192.168.2.110. The tunnel is 192.168.2.96/28. The end points are locally 192.168.1.97(eth1) and 192.168.1.1 the other side''s

Hi Guys, Here is our patch to allow broadcast packets over a GRE tunnel. Hopefully it might be accepted into the source someday. You need to enabled bridging and GRE tunnels in your kernel. No other options are required. The gre patch determines what type of protocol type to put in the GRE header based on the whether the packet is forwarded from a bridge or not. To use the patch: # Create

Hello, I connected the network 192.168.1.0 with 192.168.2.0 over the internet trough a GRE-Tunnel. I don''t know if I set up all things right: The client-pcs in both networks have a subnet mask of 255.255.255.0 and 192.168.2.x''s default gateway is the server wich has started the tunnel. The 192.168.1.x''s default gateway is 192.168.1.250 wich routes traffic destinated to

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 List, FYI. We have been using CentOS 6.4 and have 2 vpn/gre tunnels to separate cisco rtrs using ospf. with kernel 2.6.32-358.23.2 We have upgraded to 6.5 bit using kernel 2.6.32-431.5.1 and the exact same configuration scripts for our vpn/gre tunnels. What I see is the first gre tunnel works great and I get an ospf neighbor. The second tunnel comes up and I can ping across it and I see
