For basics regarding your environment if Linux is your firewall gateway appliance and you have multiple internal networks behind it, then openvpn on the gateway is the simplest most effective way to connect the networks. Ssl vpn's can be behind network gateway devices, but then depending on the type of connection between sites (site to site or road warrior) you may need to configure additional routes on the gateway or each machine to return traffic. If its on the gateway for your networks then that box decides how to route it out properly. > 2.

We do VPN's, Firewalls, and security for quite a few collocations and companies. Rarely is a company so security conscious that they want multiple layers of firewalls, and the complexity that can bring to the environment. Usually those that do have the staff on hand to troubleshoot complex networks as they need to adjust things. Not to say that this isn't done, many people do, but does your environment necessitate this level of security? If not lets stick to the single device approach. > I'll probably have more questions based on your answers and I look > forward to the responses.
