NAT connectivity slows down speed when downloading

[TziG]

I have windows 11 host and redhat 9.4 as guest OS. When, for example, I update my RHEL repositories, it starts with great speed and slows down as time goes on until I reach very slow speeds. If Bridged connectivity is used everything works fine.

I will attach some screenshots.

This is literally described in the first ticket for this version #22164. You could follow the discussion there, with all the links to the forum. This ticket should be closed as duplicate.

I do not see the relevancy in the ticket you mention. The problem there is that the adapters do not get IPs and therefore the whole NAT thing is broken.

My problem is the speed which reduces as time passes. If however you think it is the same problem (with which I do not agree) please close this ticket.

The current development snapshot should already have a fix for Linux guests. For the Windows hosts and guests, it should take some time. For more details, take a look ​here.

Thank you for the information boxer. The link indeed contains the same problem.

Looks like fixed on my Windows 10 host and Windows 11 guest combination as of 7.1.1 r164917.
