I appreciate all your help. It's still not working.
Antonio's suggestion is the syntax I already had. I mistyped my email.
I tried Paul's suggestion but it still doesn't work.
I'm not a network expert. It's probably something very obvious. I'm going
to describe my 2 interfaces more
external interface is: em0 inet 220.127.116.11 netmask 255.255.255.248
internal interface is: em1 inet 192.168.1.55 netmask 255.255.255.0
em0 is running at 100 half duplex
em1 is running at 100 full duplex
nat on $ext_if from $int_if:network to any -> ($ext_if)
rdr on $ext_if proto tcp from any to $ext_if port 80 -> $webserver port 80
NAT is working perfectly fine. I can ssh into em0 and then telnet to port
80 and do a GET on index.html.
It's a brand new FreeBSD 5.3 install. I updated to 5.3 stable and rebuilt
the kernel only adding the following to the configuration
options ALTQ_CBQ # Class Bases Queueing
options ALTQ_RED # Random Early Drop
options ALTQ_RIO # RED In/Out
options ALTQ_HFSC # Hierarchical Packet Scheduler
options ALTQ_CDNR # Traffic conditioner
options ALTQ_PRIQ # Priority Queueing
options ALTQ_NOPCC # Required for SMP build
