I have around 100 users at our site that would require the use of squid, we house are own webserver, mail server, public DNS servers in the DMZ and 2 private DNS servers on the internal network, used by both Internal and VPN users. Sites connecting Gateway to Gateway, there are apprx as follows; Site 1 - 25 users Site 2 - 5 users Site 3 - 12 users Our site VPN users are Apprx 25, and about 50% of them are connected at any given time. My first thought is to put up a Firewall box that can the load of publishing many internal boxes and "publish" a box with OpenVPN and another for SQUID and just keep them all separate. Will this setup put to much strain on the FIREWALL box or will it have no problem handling the NAT/ROUTING in this configuration.

(How many users will require the use of squid). I have a FBSD PIII 800 w/256M RAM as a firewall for one of our clients, with 3 OpenVPN instances running simultaneously (Two are site->site, and one is an XP-client->site). The box is also performing NAT (ipfw/natd) for the internal users, which when all are accounted for equal ~120, and I find it works great. There are about 30 users through the VPN's, though usually never on all at the same time. Depending on caching requirements though, you might be better off splitting that off onto it's own box, especially if you have the hardware readily available as you suggest. YMMV.
