Running a DCS dedicated server under wine works very well and for a "hobby" I'm willing to take the risk that it might break.
Don't worry, my "production" environments will never see Windows anywhere. But that's an off-topic discussion, I guess.
My main concern is about IPv6.
The world is rapidly running out of IPv4 addresses, they are getting increasingly hard to get and expensive and - at least in my vicinity - more and more Providers start to offer connectivity w/o IPv4 (or severely crippled, like CGN, NAT64, ...). Even large Providers like AWS or smaller but popular ones like Hetzner have started to offer IPv6 by default and make it increasingly hard to get v4.
IPv6 is almost 25 years old and I wonder why/if there is no first class support in DCS.
