Thank you. I have two more questions:
1: I am a bit confused about dealing with the NAT/DHCP issue. What has me
stumped is that if I want to do a:
block in log quick on tun0 proto tcp from any to <internal network> port = 23
block out log quick on tun0 proto tcp from <internal network> to any port = 23
What do I put in for the internal network? The IP is assigned via DHCP. Is
my only choice to use any?
2: I need to redirect some incoming requests. I am running a web server and
mail server on a machine behind the firewall and I would like incoming
requests to be redirect to that machine. How do I configure NAT to do that?
