I think I may go mad.
I installed 4.2 this morning via ftp, the install went fine.
I'm attempting to set up this freebsd machine as a gateway
between my cable modem and internal network.
I have tried the FreeBSD 'Handbook' but the section on
networking is useless. I have managed to piece together
some idea of what needs to be done from freebsddiary.org
and newsgroup tidbits.
I have NOT rebuilt the kernel, I'm assuming since the install
asks "Enable Gateway?" that the default 4.2 installation must
include the IPFIREWALL and IPDIVERT options already enabled.
The machines can reach one another, the cable modem lights
up when the internal machines attempt to talk out, but the outside
worlds response does not get back to the internal machines.
in /etc/rc.conf I added:
firewall_enable = yes
in /etc/rc.firewall I added:
/sbin/ipfw -f flush
/sbin/ipfw add divert natd all from any to any via de0
/sbin/ipfw add pass all from any to any
also done:
natd -interface de0
any assistance would be appreciated
