Cisco VPN with dynamic IP addresses

Hello, I am overseas and sadly not able to get static IP
addresses from my
ISP. So far the way I handle VPN’s is with linksys RV042
and no-ip.com
and I might add, this combination has worked good.
However, since
business is getting better, I decided to get cisco to protect
me but I
want to know if I can do the same thing since this has
worked for me so
well.
Any thoughts on this?, I appreciate your help!
