hope this helps.
I have a firewall that runs on a Sun Ultra 5. It is a dhcp client on
the
WAN side and a dhcp server inside the house. The firewall connects to a
switch that has several things connected to it including other computers
(running various operating systems), switches that service other parts
of
the house and a Linksys wireless G access point.
I have a company HP laptop that runs Windows XP. The laptop has a built
in 802.11 capability and a PCMCIA card. The card works fine, but the
built in will get through the WAP fine, but won't get an IP address from
the firewall.
Is there some log file where I can look for error messages to try to
troubleshoot this.
Thanks again, and I hope this helps explain things.

I'm not certain this is useful, but that *is* the message you get if
pf
blocks a packet. However, dhclient does some unusual stuff to be able
to
send packets even when the interface is down, and usually bypasses pf
because of that.
Otherwise, it's not really clear to me which host is which and which
host is doing what, so I'm afraid I can't really help you. A little
clarification sent to the list might be useful here.

that is a classic: dhcp uses UDP broadcasts which usually are not
forwarded, your AP is not your dhcp-server and so the dhcp request will
reach the AP but not your firewall.
Three solutions: dhcp relay agent on your AP (if possible) or configure
your AP to forward broadcasts or use a dhcp server on your AP with a
different IP range.
Try any search machine with "dhcp relay" and you will find answers.

What I don't get is why does the PCMCIA wireless work ok and not the
onboard? I assume the PCMCIA also gets it's IP from the AP.
The OP didn't write that so I assumed PCMCIA ist wired.
