Combining source and destination NAT in the same policy (388718)
The Service field has been added to Virtual IP objects. When service and portforward are configured, only a single mapped port can be configured. However, multiple external ports can be mapped to that single internal port.
config firewall vip edit “vip1” set type load-balance
set service “HTTP-8080” “HTTP” <—– New Service field, accepts Service/Service group names
set extip 188.8.131.52-184.108.40.206 set extintf “wan1” set portforward enable set mappedip “220.127.116.11”
set mappedport 100 <——– single port end
The reason for making this configuration possible is to allow complex scenarios where multiple sources of traffic are using multiple services to connect to a single computer, while requiring a combination of source and destination NAT and not requiring numerous VIPs bundled into VIP groups.
