Softether VPNSERVER 99% cpu Usage #1239
Comments
Could you try to enable |
@davidebeatrici Yes. It was already enabled. But still no luck. vpnserver always stuck at top of cpu usage. |
Had exactly the same issue and fixed by configuring tap instead of using bridge on interface, in my case it's a KVM VM. |
@DainBB Can you send me a guide? Or, tell me what you did? |
Connect to VPN server in Server manager - Click Local Bridge Settting At the bottom part of the screen pick Virtual Hub name from dropdown list, then instead of default "Bridge with Physical Existing Network Adapter" choose "Bridge with New Tap Device" That's it, you should see tap_"name" in ifconfig -a output on your server and you can enable SecureNAT after that, on my VM CPU utilization never goes above 10% with this setup, before I created tap it was 80% on idle. |
@DainBB Thanks a lot mate. But I am in a rush, can you please explain the SmartNAT part? That would be a great help. |
It's SecureNAT, sorry, you know how to enable it. |
@DainBB did you make any change in the SecureNAT config with new TAP interface? |
No changes, all default settings |
@DainBB Thanks again mate! You are awesome! |
Hi @AdroitAdorKhan nice to meet you and sorry for sounding your inbox, DainBB's solution is works good for your problem? That time, found caused by LOCAL BRIDGE and SECURE-NAT bothes enabled. AdroitAdorKhan's problem is like this? |
Hello @libnumafly I used a different approach there. I used dnsmasq and bridge, and it's working super fine now! |
Got it, thanks reply @AdroitAdorKhan ! |

Description
[Description of the bug]
Whenever I use securenat on my kvm server, cpu usage goes to 99%. Even with zero user connected, just whenever I enable securenate, vpnserver usage goes to 99%+-. And, it causes issue with the internet speed.
