Natd/Gateway=yes vs 5.3

[Francisco Reyes]

Migrating a 4.10 box.
Copied data to a second drive.
Installed 5.3
Changed kernel to add

options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         "IPFIREWALL_VERBOSE_LIMIT"=50
options         IPDIVERT

In /etc/rc.conf have
firewall_enable="YES"
firewall_logging="YES"           # Set to YES to enable events logging
firewall_quiet="NO"
firewall_type="open"
gateway_enable="YES"
natd_enable="YES"               # Enable natd (if firewall_enable == YES).
natd_flags="-f /etc/natd.conf"  # Set rules file for the NAT daemon
natd_interface="ed0"

Not only the machine is not acting as a gateway, but it doesn't let me 
even connect to the internet.
Looked at ipfw list and saw

00050 divert 8668 ip from any to any via ed0
00100 allow ip from any to any via lo0
00200 deny log logamount 50 ip from any to 127.0.0.0/8
00300 deny log logamount 50 ip from 127.0.0.0/8 to any
65000 allow ip from any to any
65535 deny ip from any to any

Added a pass all rule before the divert and I am able to see the internet 
from the FreeBSD machine, but not from the other machines.

Anything changed for nat between 4.10 and 5.3? Any suggestions?
