I'm forwarding port 5800 to a certain computer. However, I only want 4 WAN IPs to have access to this port. How would I set up the filters?
Originally I was setting up a filter with 4 rules. Each rule was for 1 IP and if it matched it would forward the packet, and if it didn't match it would go to the next rule. Then the last rule would drop the packet if it didn't match. If it matters, I had the destination IP and subnet as 0.0.0.0, and the port as 5800.
But this won't work will it? What will the filter do with packets not from those 4 IPs? It will just forward them right through won't it? I'm getting a big confused here.
Thanks for any help!
Edit: Also so you know, I applied the filter to the incoming LAN section. I assume that's right.
