Hammer & Screwdriver Ipfilter question
Howdy

My goal is to block locally the applications on a Solaris 10 server to access specific port on a remote machine. All attempts to access the <remote ip>:<remote port> should be rejected with ICMP port unreachable or with TCP RST.

I tried with the following:

Code:
block return-icmp(port-unr) out proto tcp from any to 10.118.128.79/32 port = 1521

and

Code:
block return-rst out proto tcp from any to 10.118.128.79/32 port = 1521


In both cases connections to this IP/port are timing out instead of being rejected right on the spot.

For example the below works just fine in Linux:

Code:
# iptables -I OUTPUT -d 10.118.128.79 -p tcp --dport 1521 -j REJECT 
# telnet 10.118.128.79 1521
Trying 10.118.128.79...
telnet: connect to address 10.118.128.79: Connection refused

install-solaris

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
