im trying to figure out how to do this in an SRX
I need: (example ips and ports)
traffic to internet ip 18.104.22.168 port 500 nat to DMZ ip 22.214.171.124 port 500
traffic to internet ip 126.96.36.199 port 501 nat to DMZ ip 188.8.131.52 port 501
I dont think this should be to hard but search round im not sure if im using the correct term or not
Destination Nat should do this right?
Yes you want to use destination nat with one address port forwarding to many servers.
See the example on page 9 of this NAT examples documentation.
