Hello All
   Here is my question; when using PF  can I create a const table made 
up of predefined lists.
Here is my example it does not work I am using FreeBSD 7.1-RELEASE i386 .

=============================

ext_if="bge0"
int_if="bge1"

#My Netgroup lists
NETGROUP_SJL  = "{ 10.70.123.218 10.70.123.112/28 10.70.118.192/26 
10.131.146.132 }"
NETGROUP_LON  = "{ 10.72.241.218 10.72.241.192/28 10.72.241.32/27 }"
NETGROUP_EWR  = "{ 10.27.64.218 10.106.131.0/24 10.27.64.212/30 }"
NETGROUP_HKG  = "{ 10.168.209.218 10.168.209.40 10.168.208.100 
10.168.209.192/28 }"
NETGROUP_BACKUP = "{ 192.168.12.0/26 }"
ISILON_SMQ = "{ 192.168.14.0/24 }"

table NETGROUP_ALL const { $NETGROUP_SJL $NETGROUP_LON $NETGROUP_EWR 
$NETGROUP_HKG $NETGROUP_BACKUP }

# Do not filter lo
set skip on {lo0}

# Normalize
scrub in

# NAT the internal network to the outside world
nat on $ext_if from !($ext_if) to any -> ($ext_if)

# Begin Firewall rules
block in
pass out

pass quick on $int_if no state
antispoof quick for { lo $int_if }

pass in quick on $ext_if inet proto tcp from NETGROUP_ALL to ($ext_if) 
port 22

===============================


The issue is when I test out the rules with pfctl -vnf /etc/pf.conf I 
get the following error

/etc/pf.conf:15: syntax error
set skip on { lo0 }
no IP address found for NETGROUP_ALL
/etc/pf.conf:33: could not parse host specification
%

Any ideas ?
