I'm new to arduino and I've been having lots of fun learning it. The only question I have so far is if there's anyway of securing ardunio as a server or putting a firewall on it. Specifically, I wanted to only allow certain range of address (vlan) to access my arduino. I've been googling for couple of days now and never found anything about this subject.
So far the only solution that I could think of is not to use it as a server. Instead, create a LAMP server and just pull data from arduino. Just looking for you guys' input before I go ahead on this direction. Thanks in advance!!
