Hi, Please, advice - what i did wrong with configuration of my snort 
install - i can't see any openvpn traffic with my current snort config, 
thru i can see regular traffic, pptp, ipsec.

Snort installed on one server together with openvpn, openvpn has 3 
interfaces: tun0, tun1, tun2.

If i run snort manually and use tun* as parameter for interface - it 
works, and i can see traffic in console.

i.e.:  snort -dev -i tun0

Maby some problems with configuration of interfaces?

My current config:

# Setup the network addresses you are protecting
ipvar HOME_NET any

# Set up the external network addresses. Leave as "any" in most situations
ipvar EXTERNAL_NET any

Whole snort.conf:
