BulletSponge Posted December 27, 2019 Share Posted December 27, 2019 Hi Duma-team, my work VPN is being switched to Always-On-VPN. I am a tester for this and I am experiencing difficulties. Setup is as follows: work-laptop --> R1 (with DumaOS) --> modem/router-device (bridged) --> WAN Basically, a connection is established and some services/applications work (like intranet or e-mail-service) but overall speed is very low. What I can't do is connect to a filer/filer shares. Logfiles show (according to my VPN-administrator), that I am connected and network diagnosis shows that the filer is contacted, but no response is given. I already tried disabling QoS, but unfortunately no improvement. Changed test-setup as follows works: work-laptop --> modem/router-device (bridged) --> WAN Any idea what could be the cause? Highly appreciate your support. Cheers. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted December 27, 2019 Administrators Share Posted December 27, 2019 What kind of speeds are you getting? Just to double check are you using a PC client or using the Hybrid VPN feature on the router? How did you disable QoS through the Anti-Bufferbloat options and disabling completely?

BulletSponge Posted December 28, 2019 Author Share Posted December 28, 2019 Hi Fraser, the speed is appoximately around 5 Mbit/s. Always-On-VPN is a MS-solution, using a VPN RAS Gateway for point-to-site VPN connections for remote client computers. It is pre-configured on my laptop, so whenever I am not directly connected to my organization's network, it will automatically try to establish remote access when I connect for example to my home network (wireless or wired - doesn't matter). Therefore it's more like a PC client you don't have to start separately and I am not using the Hybrid VPN feature (no config file has been given to me by my company). I used the disable QoS-feature in the OS-QoS menu as you assumed, giving me the appropriate warning in regard to QoS, which I accepted. I've been working my way through other VPN-related forum topics concerning VPN difficulties. Could there be challenges regarding the protocol (Always-On-VPN uses IKEv2 and SSTP) or the Open VPN-version? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted December 28, 2019 Administrators Share Posted December 28, 2019 That's very odd it doesn't work with QoS off as there shouldn't be anything else that is affecting the network in that way. Have you tried port forwarding the required ports for the VPN to your device? I assume the device also isn't in the Geo-Filter? Link to comment Share on other sites More sharing options...
BulletSponge Posted December 29, 2019 Author Share Posted December 29, 2019 Hi Fraser, yes the device is not in the Geo-Filter. I'll try the port forwarding. But I'll have to ask my VPN-administrator which are the correct ports and at the moment it's holiday season so that's gone take sometime. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted December 29, 2019 Administrators Share Posted December 29, 2019 Until then put port forward ports 1-65535 TCP/UDP to the PC just to see if it would work at all, if it doesn't then that isn't the issue. Link to comment Share on other sites More sharing options...
BulletSponge Posted February 1, 2020 Author Share Posted February 1, 2020 [Solved] Hi Fraser, sorry for the late response, but port forwarding wasn't the issue. We solved the problem by lowering the MTU-value within the Always-On-VPN-configuration (1300). Now it works. The R1-setup/configuration is as I always used it. Nevertheless thank you for your support. Netduma Alex 1 Link to comment Share on other sites More sharing options...
