Hello All,
I have worked by butt off on this, reading everything I could find on the
subjects. Some reason I can't get this to work. I know it is probably
really simple, but could someone please help me?
I am configuring an IPFW firewall that will act as a gateway and run natd.
It will be on a Dynamic IP cable modem. There will be 25 users behind it.
I cannot get my card to remain connected, it keeps dropping its addressing,
or so it appears in IFCONFIG. I have included below outputs of various
processes for you all. Thank you in advance for any help you are able to
offer.
Curt Micol
