Sorry, let me clear things up.
there are 3 devices on my LAN, a notebook (10.0.2.6), a server
(10.0.2.5) and the m0n0wall box (10.0.2.30)
the WAN port of the m0n0wall box isnt plugged into anything, it is not
active, only the LAN port is being used at the moment while i set things
up which is where 10.0.2.30 is being used.
I want to block packets coming from clients on the LAN (notebook &
server) going to the m0n0wall box.
I.E i want to stop 10.0.2.5 from accessing m0n0wall's web gui
configuration page, which is why i put in the "block TCP from 10.0.2.5
to *". I know this is a very broad rule just to stop https, but I
started off with a rule to block just the specific port and it did not
work, thats why i broadend it to all hosts/ports.
The rule to block ICMP from any to any was put in to stop any host on
the lan (laptop or server) from pinging the m0n0wall box, which also
does not work - any host on the lan can ping m0n0wall and m0n0wall can
ping any host on the lan. The rule simply isnt working in either
To give you further proof that this isnt some stuff up of mine, I
_removed_ the pass rule that allows the lan to access anything - there
are NO allow rules anywhere in the firewall, this should block anything
and everything however it does nothing - even after a save & reboot.
I'm truly stumped by this problem.
