VPN Bandwith slow

[Jose_aisos]

Good morning dear, I have a problem with my VPN, I have 2 links (100MB and another of 120) I want all the VPN traffic to go through the 120 link but when they connect to the VPN and I do a speed test it only reaches to 3mb. I have MX100

Are you talking about Client VPN or Site-to-site VPN? Have you checked if it's not an ISP issue?

[Jose_aisos]

Thank you very much for your answer, the type of vpn is client.

[alemabrahao]

Is it necessary for the client to use the MX Link to go out to the internet? Could they go out over the local internet?

[Jose_aisos]

The user could not necessarily use MX to go online, we use an ERP and at times it gets slow, but in the office there is no problem.

@Jose_aisos what bandwidth does the user have, or is it 100Mb/s for the user and 120Mb/s for the site with the MX?

What software version is the MX running and what client VPN is it (AnyConnect or legacy)?

[Jose_aisos]

I use the 100mb for my office and the 120 I want to use (100%) for my VPN

Is this using the Microsoft L2TP client VPN, or Cisco AnyConnect?

[Jose_aisos]

hello Felipe,

I'm using Microsoft's L2TP connection because anyconnect is licensed, right?

[PhilipDAth]

Correct, AnyConnect needs a licence - but it is 100% worth it.  It is so much better.

A couple of things you can try; try enabling timestamps on both the client and the server they are accessing:

netsh int tcp set global timestamps=enable 

If that doesn't work, try reducing the MTU on the client.  Run this command to display all the interfaces:

netsh interface ipv4 show subinterface 

Pick out the name of the interface the user is using, and then:

netsh interface ipv4 set subinterface “Ethernet” mtu=1300

 Change "Ethernet" to the name of the primary interface on the machine.  If this solves it, run the command again and add "store=persistent" to make the change permanent.

[Jose_aisos]

I just did what was indicated but the maximum that the speed reaches is 9mb, despite the fact that a rule was created for it to use 20mb for upload and download

[PhilipDAth]

Have you got any bandwidth or traffic shaping rules configured?

[Jose_aisos]

Indeed, I have configured traffic shaping rules
