40have a dynamic IP address from your ISP.Public End IP: This is the ending Inside Public IP Address. This field is N/A forOne-to-one, Many-to-One and Server mapping types.Using port forwarding does have security implications, as outside userswill be able to connect to PCs on your network. For this reason you areadvised to use specific Virtual Server entries just for the ports yourapplication requires, instead of using DMZ. As doing so will result in allconnections from the WAN attempt to access to your public IP of theDMZ PC specified .If you have disabled the NAT option in the WAN-ISP section, theVirtual Server function will hence be invalid.If the DHCP server option is enabled, you have to be very careful inassigning the IP addresses of the virtual servers in order to avoidconflicts. The easiest way of configuring Virtual Servers is to manuallyassign static IP address to each virtual server PC, with an address thatdoes not fall into the range of IP addresses that are to be issued by theDHCP server. You can configure the virtual server IP addressmanually, but it must still be in the same subnet as the router.Attention
