natmap {[add] | [del]} [WAN port] [LAN port] [LAN IP] [protocol] [ip_cnt]

[root@sylixos:/root]# help natmap         
add or delete NAT maps.
eg. natmap add 80 80 192.168.1.2 tcp (map webserver as 192..2)
    natmap add 80 80 192.168.1.2 tcp 5 (map webserver as 192..2 ~ 192..6)
    natmap del 80 80 192.168.1.2 tcp (unmap webserver as 192..2)
