access to outlook web access through Openbsd

[Big John B]

I changed OWA to allow anybody in the Exchange folder on the 2003 server. Did not add any security , just wanted to make work before I tightened it up. Updated the pf.conf to redirect to the internal Exchange 2003. Can't seem to get there. Works internally.
Openbsd 4.0

rdr pass on $ext_if proto tcp from any to any port 80 -> 192.168.254.99 port 80
pass in quick on $ext_if proto { tcp, udp } from any to 192.168.254.99 port 80 keep state

Problem with my rdr and pass in?

thanks
