I've had Cisco 1811W router for 5 years and it's no longer supported. I have used it for:
- VPN for remote user access
- having internal/external/DMZ
I'd also like to be able to descent QoS, blocking P2P traffic, and it'd be nice to be able to do IDS effectively (I don't think 1811 can do all these w/o paying penalty on performance).
My questions are:
1. Since I don't have special requriements for doing complicated routing. Should I get an ASA instead of a new router which does the above at software level?
2. How do people usually determine which to choose: an ASA vs. a router?
