We have a LAN that is a router and a couple of hubs and there is one internet modem connected to that. In order to allow personal computers to have internet access, but not have LAN access, I have been linking a second router via one of the hubs ports so that we could have a separate network and all share the same internet modem. I would like to know about security. The reason for the second router is simply so that others can use the internet without being on our company LAN. Hopefully I am making sense. This is a small home based company and the LAN is for the SBS and workstations. The second router is for personal computer use. By doing it this way, am I keeping the personal computers separate and segregated from the company LAN?
