Slow download speed. The upload is normal

Post by Vamp » Fri May 25, 2018 10:01 pm

Hello there,

I use Softether server on ubuntu 18.04 (latest paskal-07 PPA release)

My config:

two network interface, ens18 and ens19 (Proxmox virtual cards)

ens18 is the main network interface that it get IP from my vyos DHCP server.

ens19 is configured the following:


auto ens19
iface ens19 inet manual
up ifconfig ens19 up


ens19 set to "bridge" interface inside on softether server.

The Client is a Windows latest official one.

If i connect to VPN server, i get IP from my "home" DHCP and everything working like a charm.

Only one problem... my download speed is maximum 350kbps (my home network is 160/60 Mbit)

The upload speed is good (about 60 Mbit)

Any idea that what is the problem? Now it is useless to me...

Other info: I not want to use SecureNAT or softether own DHCP server.

I tried some other configuration (like sofether own TAP interface bridged to ens18...) but it not working normal with me (like the client not get IP from DHCP server)

I found a dirty soluiton:

If enable secureNAT, wait a bit and disable it, it solve the problem... (i dont know why...)

So i create a little script that run it every reboot:

!/bin/bash
/usr/bin/vpncmd localhost /SERVER /HUB:vpn /CMD SecureNatEnable
/bin/sleep 15
/usr/bin/vpncmd localhost /SERVER /HUB:vpn /CMD SecureNatDisable

it solve my problem, but not the best fix....
