yes, pf for newbies... sorry

[Vim Visual]

Hi,

ahem... I am starting to play around with pf and I am trying to figure
out how my internal interface and external interface are called... I
mean dhcp and the private IP address...

I am using this by now:

ext_if="fxp1"           #the external interface
int_if="fxp0"           #the internal interface
internal_net="192.138.3.100/150"

I think I can give the internal_net a range of potential addresses
like that, right? Since it's dhcp it'll get a different one from time
to time but then I get the problem that I cannot connect:

For instance, when I try to ssh to my Institute:

ssh: connect to host bla.ble.blu.com port 22: No route to host

I am playing around with the 1st example of the Absolute OBSD site for
/etc/pf.conf,

http://www.absoluteopenbsd.com/appb.samples.txt.gz

and this is a laptop with o'bsd and connection to the net over wlan dhcp...

I promise to read the pf section in detail... but I would like to have
at least a minimal working pf

Cheers,

Pau
