I'm trying to create Nat rule for source translate when the source is address group and it will not be bi-directional.
The address group include 2 address from objects.
The source translate is Static-IP tried to put object and specifric IP address with subnet (/32)
I keep receiving the following error, also tried to use two-source address instead of address group with success.
I'm on PANOS 8.1.1

If you have more than 1 IPs on one side then you have to have same amount at other side to use static nat.
Static nat leaves port number the same so if source sends traffic out from port 1234 then after static nat source port is still 1234.
In case of Dynamic IP And Port option source port is changed so multiple source IPs can be behind one IP.
In your case you have to use Dynamic IP And Port option.
This will work (bi-directional static nat for a bunch of ip addresses) only if you set your original source addresses to a subnet (not a group object) and the subnet mask needs to exactly match the translation subnet
@Raido, for the dynamic IP and port it allows my to apply that Nat rule.
How it will behave if those servers are exhcnage servers in DAG design and the outbound traffic is 25 SMTP.
Does the smtp traffic will work on the other end? sending emails out?
Email systems really don't care about the source-port the traffic is coming from; the traffic just need to hit and open port on the other end.
