Windows 7 Openvpn Connection freeze / UMTS

flyingconsulting

Hi all,

I have an Problem with many Windows 7 and Openvpn 2.2.1 Notebooks. The Login works fine and the connection is shown green. The connection through the vpn works for minutes well. After few minutes the send a receive data through the vpn tunnel doesn't work, the connection is still green.

If I use the Openvpn over UMTS Mobile Connection the connection is green, but no data can be send through the vpn tunnel.

I have customized the config file:
route-method exe
route-delay 2
The adapter shows the domain of our network and not "unknown network"

Some resolution works in the past (deactivate all network adapter include openvpn) - but not for this circumstances.

I have no idea to fix this problem.

Thanks a lot for your help !

Server and Clients works fine with Windows XP as Client Operating System. But Windows 7 make the whole chaos.

Are you having all Internet traffic routed through the VPN when connected to the VPN?

Yes I route the whole traffic through the tunnel.

Hi.

At least show configs for Win7 client you are using.

No problem here it is the client config on Windows 7:

# Client
# - "tls-client" und "pull" wird automatisch gesetzt
client

# Device
# - tun: Routing
dev tun

# zu benutzender TAP-Win32 Netzwerkadapter
# - OpenVPN
dev-node OpenVPN

# Protokoll

proto tcp

# VPN Server

# Authentifizierung

Did you try OpenVPN connection on Wn XP also thru UMTS Mobile Connection?

May be UMTS Mobile Connection is not stable.

Perhaps you have the same situation that I found? I know the freeze green GUI.
Please make a look in the thread that I open "Windows 7 x64, routing, DHCP and a unstable VPN"

If true, than please make a reply also in this thread to document this. And perhaps my "bad" solutions works also for you.
