Hi all,

I have a macro defined such as: 

EXT_IF="tun0"

I want to refer to this interface in parentheses in case tun0's DHCP
ip address changes.
However, when I use the (...) feature in the following rule for example:

block return-rst in log on ($EXT_IF) proto tcp all

I get "/etc/pf.conf:83: syntax error"

I can't see anything odd about my rule except for tun0 is a virtual interface.
Should or can I use 'ppp' for $EXT_INT ?

 Cheers

 - aW
