QOS for printing over IPSEC tunnel

[DeWilde]

Hi, I was wondering if it is possible, regardless of the number of printers, to limit the bandwidth consumed by an IPSEC tunnel to get the print jobs "over the line".

We work via RDP on a Server in Azure Cloud. The users make a connection from the office, via RDP, to the server within the Azure Cloud and use the IPSEC tunnel that has been set up between the OPNsense at the office and the Azure Cloud infrastructure.

On the RDP server, 3 printers are defined by their IP address (which refers to the office). So when printing, that flows back over the IPSEC to the printer in the office. However, with large prints they saturate the line and the image of the RDP sessions stutters...

I found the following article in the docs:
https://docs.opnsense.org/manual/how-tos/shaper_dedicated_bw.html

is that what i need to do to get this to work. With any change that I have to specify 3 IPs at destination in the rule? or will this not work?
