We have a RUT955 router with a stable mobile connection. To remote access the devices connected to the router we have setup an OpenVPN connection, this is all working fine and as expected.
But when the connection has been made from the RUT955 to the VPN, the office network becomes really slow. Networkdrives become unavailable and remote access to servers drop. The WebUI of the router becomes really slow as well.
The logs of OpenVPN in the webUI display a lot of warnings like these:
Tue May 7 14:06:46 2024 daemon.err openvpn(OpenClie)[5837]: Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #514698 ] – see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings
In the system logs there are varying errors but there are a lot of them as well:
daemon.info dnsmasq-dhcp[6061]: DHCPDISCOVER(br-lan) no address available
daemon.info dnsmasq-dhcp[6061]: DHCPNAK(br-lan) wrong server-ID
daemon.info dnsmasq-dhcp[6061]: DHCPDISCOVER(br-lan) no address available
What could possibly be the issue of the severe network degradation?
Thanks in advance,
Rowan
