Simply put, my question is, Why would a switch port become disabled automatically when trying to use a VPN service through it?
I have a managed Netgear switch on a home LAN, which I use to funnel the PCs internet connections into my router. On one of these machines running a Linux OS I recently installed OpenVPN, which I want to use for connecting over Internet to a service provider's server. This is the first time I ever tried using a VPN service from the LAN. When I tried connecting to the server with UDP on port 1194 it fails to make the connection, apparently indicating a failure like so:
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
...TLS Error: TLS handshake failed
... TCP/UDP: Closing socket Sun May 25
00:22:56 2014 us=146589 SIGTERM[soft,tls-error] received, process
exiting
However, I am quite sure that the file "ta.key" is good, and I am able to ping the remote server's IP. I was advised to try changing the protocol and port to TCP on port 443. When I do this, not only does it fail but also the port on the managed switch connected to this machine gets closed immediately. I then have to enter the admin interface of this switch and reopen the port. So, it appears as if something on the switch may be interfering with OpenVPN. I am not sure what could account for such behavior, and I was hoping someone here had an idea about it. Why would a switch port become disabled automatically when trying to use a VPN service through it?
