VPN-Bandwith, limit VPN-Bandwith to max. 80% of bandwith

Hello Uwe,

have a look here: https://support.sophos.com/support/s/article/KB-000034234?language=en_US

Hallo Uwe,

If the links supplied by Philipp don't give you a clear picture of what to do, please be more specific about whether you want to limit outbound traffic, inbound traffic or both.

Cheers - Bob

Hallo Bob,

we want to limit Inbound and outbound, if it's possible. We have a DSL (50/10) Connection, so we want to limit the traffic for the VPN (site-by-site) to max. 80 % outgoing of 10 Mbit and Ingoing to max. 80% of 50 Mbit.

we want to limit by %, because DSL are not garanteed.

Cheers - Uwe

There's no option to do QoS by %, Uwe, just by Mbps.  Even then, limiting non-TCP traffic is not totally predictable.

For outbound, make two Bandwidth Pools on the External interface.  In order:

1. Guarantee 1 Kbps to External (Address) -> IPsec -> Any
2. Guarantee 2 Mbps to Any -> Any -> Any

For inbound traffic, only one Download Throttling rule is needed on the External interface.  Assuming that speed never drops below 45 Mbps:

Limit to 36 Mbps for Any -> IPsec -> External (Address)

Any luck with this approach?

Cheers - Bob
