Don't laugh. I'm trying to play on a minecraft server that I enjoy because I get low ping to their server, but ever since their host changed, I've been getting higher ms. This is strange because I live in Korea, and the old host was in Singapore, and now its moved to Japan, which is closer. I get 100 more ms to that server now and I've run an mtr which got even stranger results. I've done the same on my mac and again, the same results. I asked one of the server owners, and they said it was that my router was "blocking" the packets. I don't know what this means, and if my router is blocking the packets, ,what can I do to fix it. Also, I noticed that any ip I connected to, I still got a bunch of "No respone from host" messages. The first mtr here is the one to the server that I want to play on. And the rest are just examples.

The no response in general does not mean a lot, a firewall either on your PC or router may be limiting certain type of ICMP messages but allowing others.

What is really strange is how low the latency is for the first 2 examples. With ping numbers that low it means the device that is responding is inside your house.

It's definitely not in my house. Do you have any solutions on how to disable this firewall?

It's not a problem with the server. Over 100 people play on it sometimes and they get ping that is fine.

Try to run tracert and ping manually.

If the server is not in your house then the tool is telling lies. It very clearly says the average time is 1ms.

Even from your house to a server in your city you generally see 10ms because of the overhead and the distance. Not sure how the fiber runs or the actual distance to between korea and japan but I would expect at least 50ms but it could easily be over 100ms if the path was not optimum.

I know that you are a client user and wanna connect to a server. I try to tell you, that your router/modem and firewall in windows can be configured, so the ports you need to rapidly connect to the server are definitely open.

Edit: I found my router's websitre, but Idk how to log in.

Edit #2: I logged in but now everything is in Korean.

This might actually be the issue, because I checked the port and it seems to be closed. The problem I'm encountering now is that I use an SK brand router so there is no guide for me to follow on how to port foward.

Nope definitely not, but I found the port forwarding section on the site and I tried it with a static ip address and everything, but it won't work.

Oh btw, theres an extra category when you forward a port, and when i translated it, it was "internal port". It was an optional category, but do you think putting something in there could help?

I suspect you have gotten side tracked. Is your problem that the game has higher ping times now or does it not work at all.

If the game is responding then it is not ports being blocked. When that happens the game does not work at all.

Higher ping times represent delays and most time this is related to the distance the signal needs to travel.

Oh well yeah, I can still connect fine, its just that I get strange ping. I tried doing a tracert and everything showed timed out.

That just means the testing tools are being blocked by something. It makes troubleshooting very hard.

Then again lets say you were to discover that the delays were because your ISP and the server ISP only connected in say singapore. So your traffic instead of going over some direct fiber to japan it goes all the way to singapore first. There is little you can do about this.

There are lots of tools like looking glass that let you run trace from ISP routers. As a example http://bgp.he.net/. I use this one as a example because it also lets you see the bgp peering information between ISP. There are likely better ones from ISP based in korea or japan that will have more routers. If your ISP has one it is the best option.

Still other than to understand why there are the delays there is not much you can do to fix them.

Your only real option is to change ISP to one that would use a more direct path to the server ISP. Generally the best would be a larger ISP that both you and the server were on but is seldom a option.

It takes a lot of research to know which ISP use which fiber. I know little about korea ISP but I do know that most the fiber from the USA goes to japan

Wow thats pretty depressing. I'll do a little more research, but if it takes that much effort, I'm just not gonna bother.
