If you use a router and do not have the appropriate settings, you may get a low ID. Routers are equivalent to the shields that are in front of the network, masking the IP addresses of the computers in the LAN. When other customers want to establish a connection with the emule (mule), they will only get the IP of the router, not the actual IP of the computer running emule.
To avoid this situation, the following ports need to be set: The TCP protocol for Port 4662,4711 and the UDP protocol for Port 4672, all need to set the allowed direction for incoming connection forwarding (mapping). Check the router manual for the following keywords: port forwarding (port mapping), dmz-demilitarized Zone, filtering, and rules. Many routers have a firewall built in, so make sure that the same port is set up there (see firewall).
Attention:
When using a router in the network, the option DHCP-Dynamic Host Configuration Protocol is best to shut down and assign a static IP to each client in the network. It is then set in the client's Windows network connection-> The local connection-> Properties->internet Protocol (TCP/IP). You need to disable automatic access to IP addresses and enter an IP address in the 192.168.xxx.xxx range in the following IP address column. Different types of routers may have different internal IP address ranges, check the router's manual.
After you enter a valid IP address, the subnet mask column automatically changes to 255.255.255.0. The last step is to enter the IP address of your router in the default gateway column.
