similar to: GRE over IPsec Cisco<-> Linux

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 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

Hi, In XenServer5.6 FP1 beta, I have switched default bridge to open vswitch, I wonder how to use "xe tunnel-create" to create a GRE tunnel. my commands: xe tunnel-create pif-uuid=eth0_uuid network-uuid=network_created_by_xe_network_create then I got an uuid which is "access-PIF" of output from "xe tunnel-list". what should I do next? how to set remote_ip

Hello everyone, I have a problem regarding gre tunneling, I have two linux box both of them has a private network and the linux A is connected to the internet via wireless radio and the other linux B is connected to the internet via lease line. Here is the setup of my two linux box Linux A eth0 = 203.189.x.1 (internet) eth1 = 192.168.1.1 (going to hub private network) Linux B eth0 = 205.198.x.1

Hey guys I''ve been beating my head on this for a few hours. Maybe it is just a stupid configuration error you can point me at. First here is a small diagram of what I am trying to configure: http://6bit.com/img/netdiag.png Currently I only have Shorewall running on the host on the right of the diagram until I can get this working then I''ll add it to the other host as well.

Hi, Does anyone tried to get ipip or gre tunnel behind NAT environments. ? i''m trying to make both side tunneling with ipip or gre with private address just like belows..

Hello, Here is my network: ------------------ ------------- ----------- Linux box ----------- GRE --------- Cisco ---------- ------------------ ------------- What I wan to accomplish. I want ripv2 to go across (both ways) through the GRE tunnel. No packets are being passed thought the GRE

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

All, With the dual-ISP support in the latest versions of Shorewall, is it also possible to setup dual-VPN with something like OpenVPN? If so, what are the high levels steps that would need to be completed? Aaron

After my / disk seemed to be failing and found many files disappeared, I decided to remove it. I moved my other disk to it's place. Long story omitted. After installing my backup of /home and seeing firefox not restart, I started it from the command line with the immediate error: Could not find compatible GRE between version 1.9.0.5 and 1.9.0.5. I'm sorry, I'm at a complete loss.

I am trying to setup GRE between two CentOS 4.5 boxes. I have tried several variations of what''s listed below, but none of them work. box1: modprobe ip_gre ip link set gre0 up ip tunnel add gretun mode gre local 66.1.1.161 remote 66.1.2.161 ttl 20 dev eth0 ip addr add dev gretun 10.253.253.1 peer 10.253.253.2/24 ip link set dev gretun up ip route add 10.2.0.0/16 via 10.253.253.2 box2:

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

Hello, Consider this function for generalized ridge regression: gre <- function (X,y,D){ n <- dim(X)[1] p <- dim(X)[2] intercept <- rep(1, n) X <- cbind(intercept, X) X2D <- crossprod(X,X)+ D Xy <- crossprod(X,y) bth <- qr.solve(X2D, Xy) } # suppose X is an (nxp) design matrix and y is an (nx1) response vector p <- dim(x)[2] D<- diag(rep(1.5,p)) bt

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

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

[Disclaimer : I'm not a network engineer] Hi, In a setup where OpenVSwitch is used with GRE tunels on top of an interface provided by tinc, I'm experiencing MTU problems and I'm not sure how to fix them. The manifestation of the problem is, from the user point of view, communication hang. And using "tcpdump -i there" displays lines such as : 18:54:00.345666 IP

I need to send multicast traffic through a GRE tunnel between two Linux routers. The tunnel works for normal IP packets, but I can''t see how to make it work for multicast.

Hello List, I know 4.9 is ancient history, but unfortunately we have several thousand sites installed. We are in the process of moving to 6.1 when it is released. Right now I have an immediate problem where we are going to install two system at a HQ site. Each of the 2 systems will have two gre/vpn/ospf tunnels to a 100 remote sites in the field. The broadband will be a T3 with failover to
