gre/ipsec loadbalancing
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.

6.5 vpn/gre/ospf breakage
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

Multicast packages dropped
Hi,
I have recently updated one of my systems from CentOs 6.4 to CentOS 6.5.
This systems is used as a RIPv2 routing server with quagga which is the termination point of some GRE tunnels.
While running CentOS 6.4 I see the multicast packages arriving at the eth0 and the GRE tunnel interface.
While running under CentOs 6.5 I can see the multicast packages arriving at the eth0 but not on the GRE

For the following set up to work, you will need a linux computer at

Libreswan IPSec Protected GRE Tunnel & firewall-cmd
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'.

unexpected drop
Hello everybody, 
I have a Linux router with an ethernet adapter and a ADSL device.
My router has a GRE tunnel connected to a remote IP address.
Using "tc" I have configured 3 different classes:
1. 290kbit rate (used for Voip Services)
2. 180kbit rate (used for GRE tunnel)
3. 80kbit rate (for generic data traffic)
For each class, using "iperf", I send some data from a PC

GRE over IPSec VPN
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:

the host on the right of the diagram until I can get this working then I''ll

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

configuration file for tunneling device
Hi,
For Ethernet and others, we have a configuration file inside
/etc/sysconfig/newtork-script/ like ifcfg-ethx where we specify ip
address, mask, type etc... For GRE tunneling, how can I specify the
parameters for tunneling device, so that I ifup-tunnel will automatically
read and start the interface and I don't have to write the below scripts
in my start-up file.

VPN through PPP

This is probably not the right place for this question, but maybe 
someone can help me out. I am trying to setup a VPN between two private

GRE Tunnel problems
Hello,
I am doing some tests in my local network to test a GRE tunnel 
configuration. I can established a tunnel but if I stop send packets 
trough the tunnel , the tunnel goes down. I need to make ping from one 
side of the tunnel to the another side to wake up the tunnel.
What could be my problem ?? Could be the VirtualBox ??
Thank you!
