Mullvad VPN duplicate packets local network sharing.

Weird problem. That just started yesterday.

• Mullvad, VPN version 2024.5.
• MacOS 14.7.1
• Split tunneling. And local network sharing.

Today, if I run a ping against my gateway, I get duplicate response packets! This wasn't happening yesterday!

If I turn off split tunneling, it goes away, if I exit mullvad it goes away. Really perplexing.

I discovered this, because moonlight stopped working after 10 seconds. While I was debugging that I was doing packet captures, and eventually I saw I was getting duplicate control signals which was confusing the moonlight client.

Spent a good bit of time trying to debug my network to see where the duplicate packets were coming from, and finally narrowed it down to mullvad! Super weird

For whatever reason, the implementation of split tunneling, causes local network sharing to duplicate packets. I am just flumaxed
