hi people first sorry for my english.

i have a pc with only one etternet card connected to a router
(172.16.0.1) which provide both internet connection and dhcp service,
in this machine i have configured a jail virtual server, the ip of the
real server is 172.16.1.36/16 and i have made a ip alias for the jail
virtual server which is 172.16.1.100/32, i want that the virtual
server respond all incoming connections from internet, i have
configured natd with next option in /etc/rc.natd:

redirect_port  tcp  172.16.1.100:22   22


in /etc/firewall.rules:

add divert natd all from any to any via rl0


in /etc/rc.conf:

natd_enable="YES"
natd_interface="rl0"
natd_flags="-l -f /etc/rc.natd"

firewall_enable="YES"
firewall_type="/etc/firewall.rules"
firewall_script="/etc/rc.firewall"

in the sshd of jail:

KeepAlive yes
UseDNS no

my firewall is IPFW2, the configuration works well however often the
conections is reset, i don't know what happen
