[PLEASE HELP] DOWNLOAD SPEED VERY SLOW BUT THE UPLOAD IS OK

Post by TAVY576 » Fri Jun 15, 2018 6:34 pm

I have a problem when I am using the SoftEther VPN. My download gets very very slow but the upload speed stays the same.

I tried to use OpenVPN client and L2TP but I get the same results.

I tried to switch to Local Bridge because I heard that SecureNAT could be the problem but it doesn't work for me or I just don't know how to set it up.

My connection with the server where the vpn server is hosted is very good (that's not the problem).

I tried to remove any speed/bandwidth limit I can find.

I will give you some ss so you can see exactly what is happening:


Speed Test before connecting to the VPN:

Hi,

On the documentation page https://www.softether.org/1-features/2. ... -based_VPN the following is mentioned:

Local Bridges must be applied between a Virtual Hub and an Ethernet network adapter which is connected to the physical Ethernet switch. So in order to use Local Bridge you need dedicated physical Ethernet adapter. (In fact, the Ethernet adapter can be shared with other purpose, such as transmitting packets physically to the Internet in order to keep the VPN Session, but it is highly recommended to prepare a dedicated one due to performance matter.)

I'm having the same trouble with speeds and my next step will be to create a dedicated network card.

Kind regards,

What OS is used for the VPN server?

What mode is SecureNAT in?

Does the VPN server work on VM?
