I have been using my pfsense box as a openvpn server for sometime now with no issues at all, I connect with tun using no compression over UDP using the windows openvpn client. For some reason now when i connect the network utilization on the tun interface shoots up to 100% in task manager and i can confirm lots of data is being sent over the interface by checking the details page, although i have no idea what since I am just sitting on the computer idle. I cannot ping the openvpn server or ping anything else since the interface is being completely flooded. Running wireshark on the tun interface i can see lots of these packets going across, enough to almost make wireshark basically freeze up.

Does anyone know what the issue might be here?
Edit: Tried reinstalling opevnpn as well, still no luck. Also seems like im not the only person who randomly started having problems with openvpn for what seems like no reason.
tcpdump
. Use the-c
parameter to limit the number of packets captured. If you’ve checked that there are no privacy concerns, it would be great if you could provide the capture for us to analyze.
