I have a site-to-site vpn setup between my home and my office. I am using 2 Sonicwall devices...a TZ-170 at home and a Pro2040 at work. Should I be concerned about leaving the VPN connection active 24-7? I am using a DSL connection at home and a T-1 connection at work. I use MAC's at home and PC's at work. I just want to make sure I am not creating a security risk by leaving it active all the time. Thanks in advance.
