Bonding of IP tunnels
Hello.
Our Company is spreaded over Germany.
There are main offices an branch offices.
These offices are mostly connecte via multiple sdsl.
We build a IPSEC VPN Infrastructure using Aastaro Security Gateways appliances.
It seemed that only one VPN Connetion between to offices could be established.
There is no chance of bundeling multiple Connections to improve the availabilty and speed.
MLPPP is not supported.
I evaluated a solution to establish more than one VPN tunnel between two offices.
Now i directed two ip tunnels through the VPN Tunnels (IPROUTE2).
These IP tunnels are bonded with ifenslave.

If i connect the internal Routers direct to each other all works fine.
A disconnected Link doesn't trouble.
If i connect the internal Routers via the VPN Tunnel it works fine as long as both links are established. If one Link is lost only every fourth data packet will be transmitted.

Has anyone an idea why this happens?
Is there a better Way to implement multiple Tunnels?

Thanks

networkmanager

NETWORKMANAGER(8)					      System Manager's Manual						 NETWORKMANAGER(8)

NAME

       NetworkManager - network management daemon

SYNOPSIS

       NetworkManager [--no-daemon]

DESCRIPTION

       The  NetworkManager  daemon  attempts to make  networking configuration and operation as painless and automatic as possible by managing the
       primary network connection and other network interfaces, like Ethernet, WiFi, and Mobile Broadband devices.   NetworkManager  will  connect
       any  network device when a connection for that device becomes available, unless that behavior is disabled.  Information about networking is
       exported via a D-Bus interface to any interested application, providing a rich API with which to inspect and control network  settings  and
       operation.

       NetworkManager will execute scripts in the /etc/NetworkManager/dispatcher.d
	      directory in alphabetical order in response to network events.  Each script should be (a) a regular file, (b) owned by root, (c) not
	      writable by group or other, (d) not set-uid, (e) and executable by the owner.  Each script receives two arguments, the  first  being
	      the interface name of the device just activated, and second an action.

       up     The  interface has been activated.  The environment contains more information about the interface; CONNECTION_UUID contains the UUID
	      of the connection.  Other variables are IP4_ADDRESS_N where N is a number  from  0  to  (#  IPv4	addresses  -  1),  in  the  format
	      "address/prefix gateway".  IP4_NUM_ADDRESSES contains the number addresses the script may expect.  IP4_NAMESERVERS contains a space-
	      separated list of the DNS servers, and IP4_DOMAINS contains a space-separated list of the search domains.   Routes  use  the  format
	      IP4_ROUTE_N  where  N  is a number from 0 to (# IPv4 routes - 1), in the format "address/prefix next-hop metric", and IP4_NUM_ROUTES
	      contains the number of routes to expect.	If the connection used DHCP for address configuration, the received DHCP configuration	is
	      passed in the environment using standard DHCP option names, prefixed with "DHCP4_", like "DHCP4_HOST_NAME=foobar".

       down   The interface has been deactivated.

       vpn-up A VPN connection has been activated.  The environment contains the connection UUID in the variable CONNECTION_UUID.

       vpn-down
	      A VPN connection has been deactivated.

       hostname
	      The system hostname has been updated.  Use gethostname(2) to retrieve it.

OPTIONS

       The following options are supported:

       --no-daemon
	      Do not daemonize.  This is useful for debugging, and directs log output to the controlling terminal in addition to syslog.

DEBUGGING

       The  following environment variables are supported to help debugging.  When used in conjunction with the "--no-daemon" option (thus echoing
       PPP and DHCP helper output to stdout) these can quickly help pinpoint the source of connection issues.

       NM_SERIAL_DEBUG
	      When set to anything, causes NetworkManager to log all serial communication to and from serial  devices  like  mobile  broadband	3G
	      modems.

       NM_PPP_DEBUG
	      When  set  to anything, causes NetworkManager to turn on PPP debugging in pppd, which logs all PPP and PPTP frames and client/server
	      exchanges.
