Hi,

   As the others stated you need a stealth rule, but as this seems to be
 a Windoze box, it looks like you didn't do anything to harden it, all
 those 13* ports should be there. Refer to one of the hardening guides
 that are available a bit everywhere and disable all those un-necessary
 services before going any further.

Subject: [FW-1] Check point firewall open ports


Hi all,

I did a port scan of my customer's firewall with Sync
connect on TCP and UDP ports. I find that these ports
are open.

135/tcp    open        loc-srv
135/udp    open        loc-srv
137/udp    open        netbios-ns
138/udp    open        netbios-dgm
139/tcp    open        netbios-ssn
161/udp    open        snmp
256/tcp    open        FW1-secureremote
259/tcp    open        esro-gen
259/udp    open        firewall1-rdp
262/tcp    open        arcisdms
264/tcp    open        bgmp
265/tcp    open        maybeFW1
500/udp    open        isakmp
900/tcp    open        unknown
1027/udp   open        unknown
2746/udp   open        unknown
4985/tcp   open        unknown
4986/tcp   open        unknown
4987/tcp   open        maybeveritas
4988/tcp   open        unknown
4989/tcp   open        unknown
4990/tcp   open        unknown
18183/tcp  open        unknown
18184/tcp  open        unknown
18187/tcp  open        unknown
19190/tcp  open        unknown

I find that all these ports - barring a few need not
be open. I want to be sure that if I disable these
ports on external interface , Management console
should work from internal interface. My customer's
firewall admin opines that these are required for
Management workstation. They do not connect Management
station from external interface.

I request the list's opinion on this. Has anybody
faced this before.

Regards
Rama
