Subject: Re: [FW-1] Tried to open tcp service port: Reject


Hello:

        You can try two different things:

        1) Define the service as other instead as TCP, recompile the policy
ans install it. In this way checkpoint shouldn´t treat the connection as TCP
an you will be able to connect to the server.

        2) Add this line in the file /etc/fw/lib/base.def

                #define NO_SERVER_PORT_CHECK
before this line
                #ifndef NO_SERVER_PORT_CHECK

        (this is the syntax for NG FP2 I don´t know which is the exact
syntax for FP3,I suppose is the same)

        recompile the policy, install it and try.

I hope this help.

Regards,
Mario.

Subject: [FW-1] Issues with FTP again "reason:tried to open a known
service port"


Hi

I posted this a month ago and was only able now to try one of the remedies
(to no avail).

The issue I have is my FTP transfer fails randomly with an error in the
firewall logs saying:

FTP REJECT "reason: tried to open a known service port"

I was suggested to:

        A: Disable the FTP checking in SmartDefense

        or

        B: Modify some code in the base.def file

Both suggestions have not worked.  Has anyone else seen this?

I am running on IP330s with NG FP3

Any help is greatly appreciated,

Thanks

Rob
