Connection

Profile
A connection profile with all recommended settings for new users can be selected here. Most common Internet connection configurations are shown there. When a profile different from Custom is selected, the recommended settings can't be changed.

Clientport
eMule Plus uses this port for data downloading from other clients. A random port is selected for this purpose at installation time. This port has to be accessed from outside, otherwise you will have LowID (firewalls and routers have to be properly configured).
Note: changed value will be used only after application restart.

Clientport UDP
This port handles eMule's extended protocol like Client to Client Source Exchange and source asking on compatible eMule clients. Using inter client UDP reduces the connection overhead and also lessens load on servers. If the UDP fails then eMule Plus will drop back to TCP.
Note: changed value will be used only after application restart.

Clientport Disable
With this option you can disable the UDP port. Clients will contact you via TCP rather than UDP once this option is disabled.

Download (Capacities)
Maximum capacity for downloads in KB/s. This value will be used for statistics plot scaling and for the system tray menu quick speed settings. This does not affect your download limit, but should be greater or equal to it.

Upload (Capacities)
Maximum capacity for upload in KB/s. This value will be used for statistics plot scaling and for the system tray menu quick speed settings. This does not affect your upload limit, but should be greater or equal to it.

Download (Limits)
Maximum downloads speed limit in KB/s. This setting must be chosen wisely as using the full line speed will degrade your downloads/uploads. A couple of KB/s below the data rate of your line will be ok. You won't download over this limit, even if you can.

Upload (Limits)
Maximum upload speed in KB/s. This setting must be chosen wisely as using the full line speed will degrade your downloads/uploads. A couple of KB/s below the data rate of your line will be ok. You won't upload over this limit, even if you can.

Limitless Download (enabled when upload >= 10)
This option disables download limit control -- maximal possible download speed will be used. That means that download speed will be limitless when upload limit is greater or equal to 10 KB/s (in this case 0 will be displayed in the download limit editbox), or it will be maximized according to the current upload limit (and corresponding ratio). The download limit slider in the system tray will be disabled in this case.

Queue Size
The maximum number of users allowed in your upload queue. A small number is preferred if you close eMule Plus regularly. A big number will be better if it is always on.

Max. Connections
The maximum allowed number of simultaneous connections. Having a large number (like 500) will improve your source finding and transfer speeds, but could hog your link. Windows 9x/ME can't handle more than 200 simultaneous connections; so going over it will render your system prone to crashes. Almost every home-router is limited to 256 simultaneous connections. In this case do not set the value higher than 200 to avoid problems.

In 5 Sec (Max. Connections)
The maximum allowed number of simultaneous connections to be started in a 5 seconds time frame. A setting of 20 is recommended for Win9x/ME users and Internet connections via router.

Show overhead bandwidth
The overhead generated by eMule Plus will be shown in the status bar and system tray tooltip when this option is enabled.

Enable Lancast
Lancast is a feature which enables eMule Plus to work better on a LAN. It makes eMule Plus broadcast (UDP multicast) its shares onto the LAN. Other Lancast enabled eMule clients will listen for these broadcasts and download files at a much faster speeds using their private IP addresses. Lancast doesn't break eMule Plus as a p2p application it just adds to it, promotes more sharing and saves upload and download bandwidth in LAN environments. Lancast transfer speeds are not limited by upload/download limits.

Open client ports on internal WinXP firewall
The setting activates automatic opening of the incoming UDP and incoming main TCP ports in Windows XP internal (built-in) firewall to enable unblocked communication for eMule Plus. All opened ports are closed at eMule Plus shutdown.
This feature is intended to be used only for Windows XP internal firewall.
