All of our products are running an embedded version of Linux (uClinux) that has a lot of common shell features available. IPs and ports can be firewalled on our products using ipfwadm. This is considered advanced and you should have Linux CLI experience. This is a non-supported feature.
Block port 80
ipfwadm -I -a reject -P tcp -D 0.0.0.0/0 80
Block Telnet
ipfwadm -I -a reject -P tcp -D 0.0.0.0/0 23
Block everything by IP
ipfwadm -I -a reject -S 192.168.2.249
After you have tested your rules and they are working, you'll need to add the line(s) to the end of the /etc/config/start file, save the file and then permanently save the changes to flash memory by typing:
config save
If you've blocked yourself and are no longer able to telnet/browse to the device, you will have to connnect using the serial cable to reset the camera (config clear) or change your firewall rules. Use ipfwadm -h for help.
