Dedicated server IPV6 support and DS-Lite / CG-NAT issues

[OnlyMadMax]

Hello guys,

my first post here actually!

 

I invested now hours, no actually days until I digged down to the real issue what causes me to not be able to play on externally hosted multiplayer servers.

 

I try to be really quick on the setup:

• VPS hosted by Contabo which is running a 7D2D dedicated server (set-up myself, multiple times already and worked for different Alpha's already - also plain steamCMD or linux-gsm setups were tried)
• My PC / client which is apparently only able to use IPv4 using the DS-lite mechanism (because the ISP told so)

 

So apparently this issue - or some parts of it - were already discussed or at least barely scratched in other threads (for references please read through the following):

Spoiler

 

 

How does the issue manifest itself?

1. Falling through the ground after the initially loaded chunk border is tresspassed
2. Looting is frozen / not working
3. Players & AI is stuck / moving on place
4. Actuall no disconnect by not receiving any packages
5. NO ERROR LOGS!
6. Some WRN logs when joining that "Requesting the TCP rules" failed

 

So much for the issue.

 

I see technically 2 possible solutions for this issue which are not yet there - if yes, PLEASE point me out how to do it, I'm mad desperate:

1. 7D2D dedicated server lets me configure to host on IPv6 so I can connect via IPv6 properly
2. The ISPs fixing the issue with the missing UDP support for IPv6 <-> IPv4 packet translation

 

I also see 2 workarounds, however, both are considered equally bad:

1. Play via a VPN with a static IPv4 so the packages from the server actually reach my client as "callback"
2. Ask your ISP to provide you a Dual Stack / static or real IPv4 address which they might do or might just not do, even if you'd pay

 

So my question is down to the following:

How can I start playing on externally hosted dedicated servers again?

How can I get MY OWN server connection established again?

How is the dev team reacting to the DS-lite issue? Will IPv6 be supported soon?

 

Best regards & leave your thoughts please!

Until programs actually start supporting IPv6, this is going to be a continually worsening problem. It not like we didn't see this coming either, but no one planned ahead I guess.

 

Unless you use a VPN or get a dual stack, I don't know of another fix. And the problem will just get worse as more and more ISP's drop IPv4 support. I honestly don't know why the entire industry is so behind the ball on this.

[OnlyMadMax]

Fully true, IPv6 has been around for quite some years now (>20 years AFAIK...), so it's really suprising.

I hope they won't be so slow with the year 2038 problem as well, otherwise I'm seeing a total blackout coming our way...

 

However, thinking less globally and dramatic but yet only about 7D2D I would like to place a feature request to 7D2D in order to push this topic in the long-term 

Do you know where I could do that actually? Or how I could speak to somebody of the Dev team about it quickly?
