Not everyone can connect to my server

[SuperFaex]

So, I have started a server to play with two friends. Problem is that friend A can connect without problems by entering my IP while friend B always gets the message "Can't connect to host". I've forwarded the necessary port in my router and made rules for OpenRCT2 in my firewall and it seems to work since friend A can connect. I can't find anything about this problem through a google search so I hope you have some ideas that could help.

Did friend B connect through the actual name of the server, or did he try connecting with the IP as well? 

A few days ago I tried connecting locally through the server name, and it didn't work. Instead, it worked by using the IP. What's to say that can't work the opposite way as well...

Both friends connected using the IP. It was IPv6, though. Could that lead to problems? My provider doesn't supply me with a real IPv4 address, so I can't forward any ports to IPv4.

We expect c4 and have no support for v6

Then I should probably be glad that at least one of my friends can connect through IPv6, I guess. Still, I think that IPv6 support should be added to OpenRCT2, since there are people like me out there who simply don't have access to a true IPv4 address. It would certainly make me happy.

I don't get it. Are you unable to set up a static IPv4 address? I know that most providers don't give a static one from the get-go, but setting up one shouldn't be impossible.

We only really pass the values you put in there to the system calls that handle network and give us sockets to work with. Perhaps the calls themselves are already capable of resolving IPv6, so maybe it works.
