I am trying to get natd to port redirect an external requests to port 80
to an intenal machine(192.168.70.15) also port 80. However it is not
working. Can somebody help me as to why this is not working?
I am running natd from
/sbin/natd -f /etc/natd.conf:
# natd config
interface fxp0
redirect_port tcp 192.168.70.15:80 80
redirect_port tcp 192.168.70.12:1723 1723
log yes
use_sockets yes
same_ports yes
The port redirection is not working. If I ssh into the system and then
use lynx to view the 192.168.70.15 machine, it works. When I try using a
web browser to the external IP, it does not forward/redirect.
Some of my ipfw rules are as follows:
# Outside interface network and netmask and ip
oif="fxp0"
onet="216.227.86.0"
omask="255.255.255.252"
oip="216.227.86.197"
# Inside interface network and netmask and ip
iif="sis0"
inet="192.168.70.0"
imask="255.255.255.0"
iip="192.168.70.13"
# Network Address Translation.
${fwcmd} add divert natd all from any to any via ${oif}
${fwcmd} add pass tcp from any 1723 to any setup
# HTTP - Allow access to the web server
${fwcmd} add pass tcp from any to any 80 setup
Interestingly, my sendmail works, although this is on the FBSD machine.
The 192.168.70.15 machine is a Sun box running Solaris and Apache.
My /etc/rc.conf includes:
sendmail_enable="YES"
sendmail_flags="-bd -q15m"
sshd_enable="YES"
ifconfig_fxp0="DHCP"
ifconfig_sis0="inet 192.168.70.13"
gateway_enable="YES"
defaultrouter="216.227.86.197"
firewall_enable="YES"
firewall_type="simple"
firewall_script="/etc/rc.ipfw"
natd_enable="YES"
natd_interface="fxp0"
natd_flags="-f /etc/natd.conf"
natd_flags="-redirect_port tcp 192.168.70.15:80 80"
portmap_enable="YES"
enable_rfc1323="YES"
tcp_extensions="YES"
Please reply to this address, as I cannot join the list at my office
