perhaps this is a newbye question (or problem) but I just can't
enable PORTFW on REDHAT 6.0 (kernel 2.2.5 and then upgrade to 2.2.12) .
The machine has 2 network cards
Accomplished tasks were:
- kernel recompilation with all necessary options enabled (masquerading, portfw ... - not modules)
- ip_forwarding enabled (set to 1)
- creation of rc.firewall script as:
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -s 192.168.65.0/24 -j MASQ
/usr/sbin/ipmasqadm portfw -f
/usr/sbin/ipmasqadm portfw -a -P tcp -L OUTSIDE_ADDRESS 80 -R 192.168.65.69 80
I mention that there are no errors when script is executed !
I do not have any machine outside of the firewall (this is another private network) but telneting from the firewall on
the IP of the external card (OUTSIDE_ADDRESS) no redirection happens.
Thank you in advance.
