Hi. I am trying to determine how to do the following (using a FreeBSD box):
ISP <-ppp-> [router] <---> BSD <-ether-> network
The [router] is optional if the BSD box does everything I need.
What I want to know is whether the BSD box with some software can do
packet filtering (roughly equivalent to what a router can do) between
the ISP and my network, whether I have to use the router to do the
filtering, or if I want the BSD box to do it, do I have to go all the way
and set up a firewall package?
The same question applies for this configuration:
Subnet1 <-ether-> [BSD | bridge] <-ether-> Subnet2
We need to do packet filter (again, equivalent to a router) between
the two subnets. Can FreeBSD with some software do this, or do we need
a black-box bridge? Again, is firewall software the only option for the
BSD box, or is there filtering software available. For this case
(and/or the first one) we can use 2 ethernet cards if needed.
Thanx.
