QoS and IPSec

Luke_R — Tue, 08 Mar 2022 02:10:51 GMT

Hi All,

I would like to enable QoS on an IPSec tunnel. The tunnel is carrying mostly voice and signalling traffic.

If the voice traffic has a marking, eg EF, will this marking be copied to the outer IP header (the IPSec tunnel header)?

Or, will I have to create a separate QoS policy, which prioritises IPSec traffic as it egresses the physical internet interface?

Thanks

Hello there

Is the VPN excluisvely for voice and signalling, or will there be other traffic also passing through the VPN.

You can set up QoS which is prioritize the traffic INSIDE of the VPN, over non voice traffic.

But as for prioritizing IPSec traffic, I do not think this is the ideal design.
