srp521 port forward based on source ip

[Sage Major]

I have a customer with a Sonic wall that I want to replace with a 521.

He currently has port forwaring setup so that only 3 ip addresses can access the port forward.  Everyone else is dropped.  Is there a way to do something similar?

I can make it work for a single one via the DMZ tab with a source ip address. but there is not a way I can find to add the allow for the other two remote connections.

Is it not on this router or am I looking in the right place

Hi Sage,

You can't specifically limit a port forwarding rule to a given source address.

You could try creating a general port forward though, but then add a couple of Access Control rules (Advanced Firewall Settings) to explicitly permit traffic from your trusted sources / ports and deny all otheres.
