I spend hours try to find out why I have a lowid in emule. I set port forwarding in my router. Opened the ports in my firewall etc. but I still got a lowid. I scanned with an online portscanner my ports and it told me that it is opened. So what’s the problem?

It wasn’t my settings problem. It’s because there are a lot fake servers in emule and they want to get all the traffic trsough their server. So they don’t allow high ids. After fixing my server list I finally got a high id again;-)

Thanks to this post:

To get a reliable server list free of fake ones, you can follow these steps

1. Go to Options/Security
2. Select Filter servers too
3. In Update from URL, type: http://emulepawcio.sourceforge.net/ipfilter.zip
4. Click on Load.
5. Go to Options/Server
6. Set number of errors allowed before removing the server to 9
7. Click List button that appears next to the option Auto update
8. In Notepad, that is opened, write this line and remove all others if exists:
   http://www.peerates.net/servers.php
9. Save changes in notepad
10. Untick the options to update list of servers when connecting to new server and new client
11. Click on Accept
12. Go to servers window
13. Remove all servers from static list
14. Remove all servers from list
15. In Update Server.met from URL, type the same URL you did in point #8
16. Click on Update button
17. If you have selected Autoconnect only to servers on static list add the servers you want to static list
18. Double click on any server

You need to access your computer at home or company. Or do you need to fix you relatives computer but you are to lazy to get up from you chair and visit them. So you need a remote control software. You could use vnc or remote desktop etc. But usually they are behind a firewall and it needs first a lot of configuration. And not everybody knows how to make a ssh tunnel through port 80 to bypass the firewall. Anyway if you looking for a pretty good and fast solution that most of the time works have a look here:

It is by the way free to use, but there are a couple of limitations. One important feature which is missing in the free version is that you can’t share files. Still this service is great and helped me already a couple of times.
