Dear managers,
I am referring to my earlier request with the subject "Forwarding with
IPFilter on Solaris". I am trying to redirect requests to
<external ip address of firewall server> port = 8080
to a machine in the local subnet at port 80. From the FAQs and docs I
learned that this is basic stuff and should only require the following
additional lines:
/etc/opt/ipf/ipf.conf:
===============
pass in log quick on hme0 proto tcp from any to any port = 80 keep state
/etc/opt/ipf/ipnat.conf:
==================
rdr hme0 0.0.0.0/0 port 8080 -> 192.168.1.10 port 80
hme0 is the external interface with a static ISP address. hme1 is the
interface connected to the local subnet 192.168.1.0. I expected this to
simply work after doing
ipf -Fa -f /etc/opt/ipf/ipf.conf
ipnat -v -CF -f /etc/opt/ipf/ipnat.conf
However, it does not. The connection simply times out. I did "tail -f
/var/log/fw.log" while trying to connect, but nothing is logged when I
do
telnet <external ip address of firewall> 8080
I also upgraded from ip-fil3.4.27 to ip-fil3.4.33pre2 which made no
difference. I am stuck. Has anybody got this working on Solaris 8
Sparc? Any hints would be greatly appreciated.
Thanks a lot!
Regards,
Andreas
