|

# - Example: eth1 is used for DSL Line, that becomes an extra

# - interface (maybe ppp0). A further use of eth1 (which would
|
||||
# - be possible) is not configured at time, so you can block it.

# - if using a vpn network to forward into private areas.
|

# -
|

# - Note: this rules takes affect before rules to protect against
|

# - unwanted packages e.g. blocking private addresses on
|
||||
# - externel interfaces.
|

|

# - Note: you can specify networks using CIDR notation
