easy Firewall setup

[Antonio Olivares]

Dear kind folks,

Is there an easy firewall setup available somewhere(like the one
referenced below but for FreeBSD)?

i.e, like I saw reading in Distrowatch an easy way(using a page on the
net:  http://connie.slackware.com/~alien/efg/)

I have read that there is pf and there is an implementation by OpenBSD
and both are available on FreeBSD via ports system/packages.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html

I don't know which one to use, is there a page, howto (build a
firewall or convert an existing one) to use here?  All I want is to be
allowed to visit websites but don't allow anyone out there to come in
somehow a template that I can use and try out to see if I can get it
working.  Of course the network name might be different, but I can try
to figure things out.

ne0, fe0, ra0, ..., etc

After figuring this out, my next big job/task is to use FreeBSD to
make up a new router/dhcp server to give/assign ip numbers to machines
from one and give to many.  This has been something hard that I have
failed at several times.  Maybe with FreeBSD I can be successfull?

Thanks,

Antonio
