SSH droping connections over a VPN
Hello friends,

I'm connection to an external network using a VPN configured over an Ubuntu.

The problem is that whenever I get connected to a remote computer using my VPN as router, after a while, sometimes short, sometimes long, sometimes immediately, the connection gets lost and I've to reconnect to the remote computer.

I've checked the ssh configuration on the machine running the VPN and I think the error is not coming from that way, I'm guessing the VPN somehow fails and drops the connection, I don't think this is a networking issue either because I can be connected using another vpn program like Cisco's and the connection won't fail

Any information on how could I check where the SSH connection fails would be appreciated. also, if anyone has been in a similar situation and has information I might find useful would ve very welcome.

Thanks in advance

VIRT-VIEWER(1)						User Contributed Perl Documentation					    VIRT-VIEWER(1)

NAME

       virt-viewer - display the graphical console for a virtual machine

SYNOPSIS

       virt-viewer [OPTIONS] DOMAIN-NAME|ID|UUID

DESCRIPTION

       virt-viewer is a minimal tool for displaying the graphical console of a virtual machine. The console is accessed using the VNC protocol.
       The guest can be referred to based on its name, ID, or UUID. If the guest is not already running, then the viewer can be told to wait until
       is starts before attempting to connect to the console The viewer can connect to remote hosts to lookup the console information and then
       also connect to the remote console using the same network transport.

OPTIONS

       The following options are accepted when running "virt-viewer":

       -h, --help
	   Display command line help summary

       -V, --version
	   Display program version number

       -v, --verbose
	   Display information about the connection

       -c URI, --connect=URI
	   Specify the hypervisor connection URI

       -w, --wait
	   Wait for the domain to start up before attempting to connect to the console

       -w, --reconnect
	   Automatically reconnect to the domain if it shuts down and restarts

       -d, --direct
	   Do not attempt to tunnel the console over SSH, even if the main connection URI used SSH.

EXAMPLES

       To connect to the guest called 'demo' running under Xen

	  virt-viewer demo

       To connect to the guest with ID 7 running under QEMU

	  virt-viewer --connect qemu:///system 7

       To wait for the guest with UUID 66ab33c0-6919-a3f7-e659-16c82d248521 to startup and then connect, also reconnecting upon restart of VM

	  virt-viewer --reconnect --wait 66ab33c0-6919-a3f7-e659-16c82d248521

       To connect to a remote console using TLS

	  virt-viewer --connect xen://example.org/ demo

       To connect to a remote host using SSH, lookup the guest config and then make a direct non-tunnelled connection of the console

	  virt-viewer --direct --connect xen+ssh://root@example.org/ demo
