PPTP vpn stops passing data after 30 minutes

Hi all,

I have a PPTP server defined on my router and it works fine. The only problem I have is that when I connect a client and lets say I start streaming some data from my nas, the PPTP stops passing the data trough the vpn after +/- 30 minutes and/or +/-0,5GB of data. The vpn stays connected, but my local network and internet aces through the vpn is not reachable until I disconnect and reconnect the vpn.
Any ide what might be causing such issues? - I need to achieve a persistent connectivity…

Thanks!

Hi! I have the same problem on my OmniTik 5UPA-HnD. Do you have any solution?
