HI folks,
Im using iptables and successfully configured it to be my
packet filtering firewall. I've configured nat (DNAT) to forward http,
smtp and dns request to servers inside my firewall.
However, I want to disable dnat for some reason. But I can't disable it.
I remove the dnat rules and re-run my "iptables script" to freshen the
rules, there's a flush command of course. Still it forwards the
packets to the server under the firewall.
I even issued the command
# iptables -F -> this is the command to flush all rules, right?
still dnat persists and i'm able to connect to the servers under my
firewall. There are no running services such as telnet, http, etc..
in my firewall.
Is there a bug or did I missed something? I'm using RedHat 7.2, with the
default kernel.
many Thanks,
carlo
