At work we have two types of network connections: 1) Ethernet Port 1 connects to my office's secure network. 2) Ethernet Port 2 connects to a cable modem. (We need it because the office's secure network is rather restrictive for my department's type of work). You can also tell Parallels Desktop to use Ethernet Port 2. That's very handy because Parallels needs ports that my office network has blocked. Question is, from a security standpoint, is it safe to have both ethernet ports active simultaneously? Currently, I am making one port inactive before turning on the other port. It gets really annoying over time! Thanks very much! I appreciate your tips.
