A way to load PF rules at startup using OpenVPN

[Chris Ernst]

Hi Atma

i had similar issues with exactly the same setup. I was able to solve 
the issues by using *brackets* in pf.conf
actually brackets specify dynamic IPs. By using brackets pf knows the IP 
may change.

here is an extract out of my pf.conf

user at gateway:~ # more /etc/pf.conf
intIf = "vr3"
extIf = "vr0"
vpnIf = "tun0"
[...]
[...]
### filter rules
block all
[...]
[...]
# allow from vpn to internal
pass in on $vpnIf inet proto {tcp,udp} from ($vpnIf:network) to $intNet 
keep state
pass in on $intIf inet proto {tcp,udp} from ($vpnIf:network) to $intNet 
keep state

best regards
Chris
