Port forward - allow any ports
if i want to NAT ie port forward ANY ports to my machine, whats the syntax for this * or 1-9999
Use 1:1 NAT and allow any ports in the firewall rule to this specific host.
Do these sites work to test ports?
I use can you see me all the time - works great.
Keep in mind these are valid to test with TCP, not UDP.
As mentioned already if you want to forward all ports to a box behind pfsense, then yeah 1:1 would be the better choice.
