Hi misc.
I've a openbsd 4.7 firewall with 3 nic, one for lan, one for wan and one for dmz. On the same machine I've a squid proxy, and in dmz i've a web server. My problem is when I get a request for the web server on dmz by a lan client.
In my ruleset I've this rdr rules for http request:

match in on $int proto tcp from $int:network to any port 80 rdr-to $int:0 port 3128

and it works fine for all requests.

When I make from a $int:network client an http request like "http://mydomain.ath.cx";, the proxy (working with rdr rule or browser config) give me the web managment of my router.
Then I've tried a first set:

match in quick on $int proto tcp from $int:network to mydomain.ath.cx port 80 rdr-to $apache port 80 match in quick on $int proto tcp from $int:network to $int:0 port 3128 rdr-to $apache port 80 match in on $int proto tcp from $int:network to any port 80 rdr-to $int:0 port 3128

but the behaviour is the same.

I've tried to modify my rdr rules into (second set):

pass in quick on $int proto tcp from $int:network to mydomain.ath.cx port 80 rdr-to $apache port 80 pass in quick on $int proto tcp from $int:network to $int:0 port 3128 rdr-to $apache port 80 match in on $int proto tcp from $int:network to any port 80 rdr-to $int:0 port 3128

and it works fine.

I've tried third ruleset:

match in on $int proto tcp from $int:network to any port 80 rdr-to $int:0 port 3128 match in on $int proto tcp from any to mydomain.ath.cx port 80 rdr-to $apache port 80

but doesn't work.

My question is about these three ruleset.

Why in the first ruleset match in quick rules, the key quick does not affect the third rule of squid redirection?
Why the pass rules works instead the match rules?
Why in the third ruleset match in on $int...doesn't work? The rules parsing is the "last match rule"?


thanks in advance
