Hello,

I understand both the ISR 871 and SR520 will establish a site-to-site VPN tunnel with a UC520W. However, I have two additional questions.

1. Can I use the base ISR 871 or do I need the SEC version, i.e. advanced IP security services?

2. Would an SR520 be a better choice and easier to configure? I prefer to use the GUI whenever possible?

Thank you.
