Hello, I now think my VPN is running reliably: a ping every 5 minutes over the last 15 hours has shown 100% success.
The bug was in the UPC router firmware, blocking from time to time trafic on port 4998/UDP where I run my multi-site VPN. The funny thing is that the bug showed itself not only on Internet traffic but ALSO on the internal switch of that router for two machines on the same public IPv4 subnet, and disappeared when connecting them through an independant switch. I could however clean up a bit my OpenVPN configuration, which was a good thing. Thank you for your help. _______________________________________________ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users
