This topic includes the following tasks: The show sessions output has NAT IP and NAT Port columns where the NAT’d source address and NAT’d source port are displayed. Port forwarding is great, but you can't forward the same port to two different servers, so it's more tricky to have resiliency. set applications application test term term0 protocol tcp set applications application test term term0 source-port 2099 set applications application test term term0 destination-port 22 Static NAT maps network traffic from a static external IP address to an internal IP address or network. You will need to configure source and destination nat for each ip address and add to the rule the desired other side ip address. Step 2: Configure the One-to-One NAT (Static NAT) Rule. To configure a [destination] NAT that permits 80 and 443 to be forwarded (in your case it sounds like you want to forward a public IP and port to a private IP and port) there are two steps. 179/32 set security nat destination rule-set SET_1 rule VOIP_15101 match destination-port 15101 Destination NAT (Port Forwarding) Passthrough for VPN The Juniper SRX has a private IP of 192.
