I wanted to implement a firewall that can also do Web Caching and VPN.

First, here is some info on the current setup.
UFABET
WAN1 25/25 EoC Connection
WAN2 10/2 DSL (Backup/Mail Traffic)
LAN  20 users
1 Site to Site VPN tunnel via IPSEC
We plan to possible grow to a max of 50-60 users over the next year, but should be no more than that.

What I'm looking for is mainly a Firewall with VPN (few users) and possibly Web caching.
