My company is using frame relay to connect remote offices. &nbsp;I am planing to replace existing frame relay with &nbsp;Dynamic multipoint vpn in hub sopke configuration by using cisco 1841 and 800 series routers in order to reduce cost. I wanted check is there any security issues are related with this setup since it uses Dynamic IPs from ISP in all spoke locations. &nbsp;Thanks in advance.

Dynamic Multipoint VPN

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
