Hello:
I have recently been but in charge of a Linux firewall for a small
company (15 employees) and am not very experienced with firewalling but
am learning as I go. When I examined the hub configuration, I found
that we have a hub coming in from the outside world, this hub connecting
to the firewall, and the firewall connected to a second hub for the
inside network. Now, I know this configuration is not mandatory and
asked a fellow employee if it was necessary. He says they did it to add
an additional level of security by having all traffic being forced
through the firewall. Can anyone tell me if this does truly add a level
of security. It seems to be that if I am using the 192.168.2.x ip
range, that routers will not route, for the internal machines they are
pretty safe from the outside world. Packets must still be routed
through the firewall in order to be masqed and sent to the appropriate
machine.
I ask because I have rebuilt the firewall (It was in very bad shape) and
now am looking to reconnect it. Not having this separation of hubs
gives us more flexibility in assigning ports to computers that need to
be outside the firewall vs. ones that need to be inside the firewall.
By the way, the firewall is only used to keep people out of our internal
network. We are in no way sort or form concerned about what our
employees go out to.
Thanks
