Does anyone know if this router can restrict incoming traffic to specific IP addresses. There does not seem to be any information on Cisco's web site any more.
ie Only 209.123.123.123 is allowed access to port 9100, which is redirected to 192.168.1.100
From their documentation, "From the Firewall Tab you can create and modify Network Access Rules to evaluate the network traffic's Source IP address, Destination IP address, and IP protocol type to decide if the IP traffic is allowed to pass through the firewall." It included an image showing cases that looked similar. Tom's guide has some info too.
Cheers,
