new to pf

[nobodyb]

hello experts,

I am new to pf. I would like to port forwarding 80 on my machines. Everything works fine, but port 80 is not open. I have tried my best, but still not luck. Kindly advise on how to imporve my pf.

ext_if = "tl0"
int_if = "re0"
dmz_if = "cl0"
icmp_types = "{unreach}"
tcp_services = "{www}"

match out on $ext_if from any nat-to ($ext_if)
match in on $ext_if proto tcp from any to any port 80 tag WWW rdr-to 192.168.1.3 port 80

block log all
block all

pass out keep state

set skip on lo
set skip on $int_if
set skip on $dmz_if

pass out on $ext_if proto tcp to any port $tcp_services

## below line might not be necessary, but I want to make sure port 80 is open
pass in on $ext_if proto tcp from any to any port 80 rdr-to 192.168.1.3

pass inet proto icmp all icmp-type $icmp_types keep state

pass in quick on $ext_if tagged WWW
pass out quick on $ext_if inet all keep state
pass out quick on $dmz_if tagged WWW

#By default, do not permit remote connections to X11
block in on ! lo0 proto tcp to port 6000:6010
