So you now know you have to plug the crossover cable into your laptop before
booting up the fbsd system it's connected to. I do not see any statements in
rc.conf to startup user ppp to enable the tun0 connection to your ISP so I
guess you are issuing the ppp command from the command line. That's ok. Now
your problem is the you can not connect to the internet through the FBSD
gateway. First you have to assign an IP address to your FBSD Nic card. Add
this to rc.conf
# assign IP address to Nic card
ifconfig_fxp0="inet 10.0.10.2"
Now you have to manually configure the laptop win system for LAN connection.
Win start/settings/control panel/networking/
Use 10.0.10.5 for the ip address of your Win box
Post your /etc/ppp/ppp.conf file & /etc/resolv.conf so I can see if you are
getting the DNS servers from your ISP.

It's connected with a crossover cable, I use the same cable under Win2k
and
works fine, now if I connect my laptop to my computer before I turn these
on
and then turn them on when the cable is connected I get a somewhat
different
output when I run 'ifconfig -a' as you can see:

Opened by PID 186
Now the status says active, another thing I notice in my laptop running
win2k
is the local connection status icon tells me it's connected at 100 Mbps so
I
know the card is working.

My rc.conf looks like this:

The post summary doesn't show any IRQ sharing but if I boot to win2k and
print
a summary of the device manager it shows the IRQ (which is IRQ 9) being
shared.
IRQ 09 - IRQ Holder for PCI Steering
IRQ 09 - Intel (R) PRO/100+ Management Adapter
