Above configuration represents incoming packets destined for IP 61.222.136.58~61 
will be redirected and mapped to internal hosts according to the predefined static NAT 
mapping. 
61.222.136.58 Æ192.168.1.2 
61.222.136.59 Æ192.168.1.3 
61.222.136.60 Æ192.168.1.4 
61.222.136.61 Æ192.168.1.5 
 
Note: This example doesn’t filter source IP, destination port and protocol in incoming 
packets. It means incoming packets destined for IP 61.222.136.58~61 will pass through 
firewall without any prohibition. Consider network security, you can block incoming 
packets by filtering certain types based on your requirement. 
 
D. Destination IP of incoming packets is different from WAN IP but the two IPs are in 
the same subnet? How do I configure the router to conduct static IP mapping between 
the destination IP and corresponding internal IP? 
Consider remote desktop application in Windows XP as an example and network 
environment as follows. 
IP provided from ISP: 220.130.26.50~54 
Router WAN IP: 220.130.26.52 
Subnet mask: 255.255.255.248 
Default Gateway: 220.130.26.49 
Router LAN IP: 192.168.1.1 
Internal host for remote desktop access: 192.168.111 (default gateway is Router LAN IP: 
192.168.1.1) 
Destination IP targeted by remote desktop client: 220.130.26.53 (different from WAN IP, 
but they are in the same subnet.)
