Packet Filter configuration...

Archived from groups: comp.security.firewalls (More info?)

Hello,
I don't know if i'm at the right place, but I have some difficulties to
setup my PF (FreeBSD)...

On my machine I have 2 NICs
vr0 on the Lan IP 192.168.1.2.
rl0 connected to a DSL router 10.0.0.1 router 10.0.0.138.
This machine must share the internet connection allow inbound http, outbound
connections for ftp, http, pop, smtp, socks, and possibly some P2P programs
like eMule or Kazaa...
The setup of the first four is 'easy' but for socks I don't really know
which port are invoked to transfer data... Socks port is 1080 but when the
client software is connected it uses another random port, how must I setup
my PF to allow those kind of negociations?
How those connections are established? First 'shot' on port 1080 then the
client/server selects another port?

I've already prepared my config file, but I need more infos before using it.
For the moment, I'm only 'protected' by my router's firewall, and it seems
pretty weak...

Your help will be greatly appreciated.
Thank you
