I want to configure a VPN. In the end I have a RV 120W Wireless-N and in the core an ASA 5506, is the ASA able to close the VPN with the small business RV?? if is it possible which protocol close it? Thanks Regards 

Checking the device: ISR4321/k9 the device it has 1 SFP-based port, I want to install a copper module por that port but the question is if this port is it routeable. Regards Thanks
