we are running a BM3.8 on NW6.5 using firewall, proxy and reverse-proxy services for 50 users. Internet connection is made with a Hardware DSL-Router with DynDNS.
BM-Hardware is a HP Proliant 3GHz pentium, 1GB Memory.
Now it is planned to install a VPN Server to connect some home offices and travelling persons.

Has someone experience with all these services on one box, or what is your recommendation?

Thanks in advance
