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 Ж192.168.1.2
61.222.136.59 Ж192.168.1.3
61.222.136.60 Ж192.168.1.4
61.222.136.61 Ж192.168.1.5
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.)
1. Configure WAN IP:
