several hosts with dnat

Matthias Krauss
Hi,
I've a dmz with dnat configured fine. If i do
a portscan from outside to the host in dmz then  ssh and pptp is shown up, of course this is 
configured - but on the asl - not to the host in the dmz, is there a way to tell the asl not
to offer/show  any ports on IF aliases where its
not belonging to ?
thx M.

    Matthias,

    Just trying to guess here: is your ICMP enabled on the ASL? If yes, try turning it off (both of them) and see if it works. I have both off and my network seems to not exist to pings, port scans etc. from the outside.

    Regards,
    Maurice

    P.S. You can check your firewall condition (open ports etc.) at grc.com using any of your masqueraded clients (they will look like coming out from your ASL box. There are some great security tests there.
