My main server has been having a very bad connection with 900+ ping. If I start the server on another IP address or port number, it runs fine. When looking at Netlimiter, the server has an unusual number of outgoing and incoming connections compared to my other servers, despite being empty. None of my other servers have this issue. It seems like this may be some kind of malformed packet attack, but I really have no idea. I was wondering if anybody had any suggestions.
Note: The server having the issue is 188.8.131.52:27015
Here is a Wireshark txt output:
In particular there are a lot of packets coming from 184.108.40.206, but I really do not know if that is the cause. They are going to 220.127.116.11:27015 however, which is the address of my server.
