I tried to post this question yesterday but it did not appear to work.
I need a refresher on how to use the GUI on a 3430 to block all access to the external internet by a specific internal ip.
In this case I have a device (say on 10.10.10.23) that wants to access several external connections using a mix of modes (tcp, udp, etc). Those connections are not necessary to operate. How do I block those external connections while keeping internal access (10.10.10.X and 10.10.11.X) to other computers using the GUI?
Thank you
