P2P updates going slow? Tried port forwarding?Follow

Hey guys,

I was just trying to use the downloader to get the initial client, but I was stuck at 1 local connection and averaging just a couple kb/s. I realized that I probably needed to forward some ports, but SquareEnix in their infinite wisdom has not deigned to provide us with a list of ports necessary to enable forwarding.

I wiresharked the client, and it looks like its making connections in the 55000 range of ports. I enabled forwarding on 55000-55400, and my download (and upload) speeds skyrocketed.

tl;dr: Enable port forwarding on some ports in the 55000 range to increase speed.

Don't know how to port forward? follow this guide (http://p2p.weblogsinc.com/2005/04/24/how-to-configure-your-router-to-allow-fast-bittorrent-downloads/) , but replace the 6189 with some numbers in the above range.

the port you need to forward is the port configured in the FFXIV Config program. Its on the network Tab. You can set it to whatever you want between 55296 and 55551. But you only need to forward that one port.

If anyone tells you otherwise they don't know what they are talking about.

The port specified in the config isn't the only port that I've been receiving data on. I have inbound connections on 10 different ports in that range.

Yes but its the only port that clients Initiate connections on.

You can initiate a connection to revive data on another port without it being port forwarded. In fact I would imagine you don't receive any data on that port. Its just the port that the outside world talks to you client on.



Example:

You make a connection to another P2P client.

Source port 35693 Source IP 192.168.0.20 Dest Port 55296 Dest IP 70.98.58.88

Your router receives it the packet and marks it as a translation in its NAT table.

Router makes a connection to the P2P client.

Source Port 35693 Source IP 65.88.48.87 Dest Port 55296 Dest IP 70.98.58.88

It now has in its translation table that return traffic to 65.88.48.87 on port 35693 goes to 192.168.0.1. You didn't even have to port forward this port. The router just knows to send packets destined for that port to your computer because you initiated a connection from it.

So router return traffic from the P2P client goes like this.

Source port 55296 Source IP 70.98.58.88 Dest Port 35693 Dest IP 65.88.48.87

Your router gets this and looks in its NAT table and knows to send the packet back like this.

Source port 55296 Source IP 70.98.58.88 Dest Port 35693 Dest IP 192.168.0.20

So as you can see, you don't actually need to forward all the ports. Only the one that Clients make a connection on that you didn't initiate. Thus all P2P clients that talk to you and initiate the connection always call you on port "whatever you set in the config". This is like your p2p address.

This is also necessary if you have more then one PC at your house. Because you can't just port forward all the ports to one client and expect it to work. So each person on the network needs to pick a different port. This goes the same for FFXIV, utorrent, Wow updater, ANY p2p client.

So please please please don't go telling everyone to forward this huge range of ports. Because its just flat wrong.
