Firewall configuration in OSX 10.8

Dear all,
In order to add custom firewall rules to my Mac, I was looking for an easy way to configure the built-in firewall. Many posts point to IceFloor, which seems to be a nice frontend. However, although I've enable SSH and it is listed as an exception in the simple OSX 10.8 firewall GUI, I don't see this exception anywhere in IceFloor.
Is there a way to see the currently applied firewall rules in (Mountain) Lion from the command-line or IceFloor?

Yes there is.
for PF:
sudo pfctl -sr
for every "anchor", you can list the dynamic rules like this:
sudo pfctl -a "myanchor" -sr
for IPFW:
sudo ipfw show

Basic Firewall configuration

Hello all,
I've been using Solaris 11 Express to host a server, and no matter what I do with the firewall gui utility, it won't open the ports I want to open. It clearly retains changes I made as root, but still I get connection refusals from my clients. I noticed also when I used the firewall utility, it never seemed to accept my role password for root, it just kept asking over and over again without giving me an error. I eventually made it so I could log in as root and force changes, which is how I got it to retain the changes I wanted without getting stuck in the role/credential loop. However, like I mentioned before, it's like the changes I made aren't active somehow. I've also tried disabling the firewall entirely, which seems to make no difference. Are there any good Solaris 11 Express / Firewall configuration guides out there?
Thanks.

There were some bugs in the area of root being a role and the Visual Panels client (and its back end RAD). I highly recommend
you upgrade to Solaris 11 or even better Solaris 11.1 (which was announced at Oracle OpenWorld 2012 and will be available soon).
If you can still reproduce this behaviour there we can investigate fixing it. Solaris 11 Express is no longer a supported release.

Windows 2008 R2 - IPSEC Firewall Configuration

Hi,
I want to open IPSEC between two servers with a firewall in between them. Both servers are Windows 2008 R2. I want to limit the IPSEC so that only data can flow from Intranet Server 1 to DMZ server1. (I don't want to allow DMZ server
to initiate data transfer to intranet) So, this IPSEC rule is for ONE WAY traffic.
I have asked my network team to open the following ports:
From Server1 on intranet to Server2 in DMZ:
UDP 500
protocol type 50
Protocol type 51
However, the IPSEC connectivity is failing. The server does not appear to be NEGOTIATING security. To simply the configuration, I am currently only using a passphrase to authenticate the IPSEC.
I am wondering if I have to open the same firewall ports from the DMZ to the intranet too. Can anyone confirm if the ports must be enabled in both directions to have IPSEC work? and if this is the case, I guess I would have to rely on the IPSEC
policy itself to BLOCK communication from the DMZ to the Intranet.

Hi,
Would you please tell us that how did you configure the IPsec policy?
Have you assigned the IPsec policy after you configured it?
In addition, when configuring IP filters for traffic that must be secured, make sure to mirror the filters.

B2B with Firewall configuration for Outgoing messages

Hi,
We have put B2B midtier within Intranet. We have firewall configuration for our network.
When B2B sends the business message to remote trading partner.The connection first hits the firewall. Inorder to pass through the firewall what ports do we need to open on firewall ..?
Any suggestions..?
Thakls

Hello Praveen,
Please use B2B in the rever proxy configuration with OHS. Pleae refer to 5.5 Configuring Reverse Proxies and Load Balancers in the Oracle® HTTP Server Administrator's Guide 10g Release 2 (10.1.2)
In tip.properties pleae give proxy host and port (10.60.15.24 and port 4085) and restart the B2B server and follow above document for configuring OHS in reverse proxy mode by changing the http.conf
Please let me know.

Firewall - Configuration/GUI of the Mac OS X 10.6 / 10.7 Firewall

First I would like to thank Apple
for making the Mac OS X operating system.
And thank you for the Lion update coming soon.
We properbly all are waiting to get the
Mac OS X 10.7 Lion update.
I have seen the full feature list of Lion:
http://www.apple.com/macosx/whats-new/features.html
All the great new innovation and apps is great stuff.
But I came to wonder about one thing though.
The internet apps like:
FaceTime, iCloud, iChat, AirDrop etc.
They more or less all requires custom ports on different
protocols to be opened and configurated.
Even the SIP for Facetime has to be enabled etc.
Like the FaceTime Firewall ports here:
http://support.apple.com/kb/HT4245
In the full feature list page of Mac OS X Lion
there is not listed anything about the Mac OS X Lion Firewall!
In Snow Leopard we can't configurate the Firewall with
custom ports and protocols etc.
Everybody refer to the Hanynet NoobProof and WaterRoof
firewall apps. I'm using the NoobProof my self right now.
http://www.hanynet.com
But I think the Mac OS X Snow Leopard and Lion could do with a
much better and way more easier firewall GUI to be able to
configurate ports and protocols and firewall rules and even NAT.
Isn't the Mac OS X about doing it the easy way!
I think a Firewall in Mac OS X with only a On and Off button (more or less)
wont cut it any longer!
For people not knowing about Firewall its OK to have an On/Off button,
but for the user that know about firewall, ports and protocols
it would be great to have a button to go in an be able to configurate
making rules and opening ports on specific protocols and doing NAT etc.
The Mac OS X Firewall GUI created by Bryan Hill called
"Brickhouse" and now called "Flying Buttress"
updated last in 2005!
(Which I could NOT get to work in Snow Leopard)
it had a very good and easy
to use Graphical User Interface. (GUI).
See it here:
http://www.securemac.com/firewallsecurityshareware.php
Why isn't there any like that for the present Mac OS X????
Anybody know anything that will help in that direction???
Anybody know a nicer firewall GUI or App for
Snow Leopard / Lion ???
Please comment here.
Best regards
Jesper
from Denmark.

Thank you very much for responding to my thread Thomas and roam.
Wheter it is a question to run a firewall on Mac OS X or not,
is not my question. And thank you, but I do know the difference between a
GUI for the Mac OS X built in firewall and a 3rd party stand alone firewall.
If I and properbly many other Mac OS X users choose to run with a firewall,
many of us would like to be able to configurate as WE want it to be.
Many users have special needs that require speciel configuration of the firewall.
There are other things than Apple network technologies you know!
Running a firewall or not. There is Pro's and Con's on both. It's a free choise right. I respect both.
I have 8 CPU cores and 16 threads on my Mac Pro, so I think my Mac can handle a running firewall!
"Better safe, than sorry!" As they say "Over there".
;o)
Apple has chosen to make a firewall in
Mac OS X, then there must be a reason why it is there.
And besides that.
I would bet that, the more popular the
Mac computers gets in the future and the more marketshare
the Mac computers get over the hopeless Windows platform.
The more hackers will be interesting in hacking the Mac OS X.
So a firewall would be something to consider the more Apple has success.
I think that is quite logical.
I'm sure there is almost as many undiscovered security holes in UNIX
as there is on the Windows platform. It is just a question of time
before the hackers will point their weapons against the Mac OS X.
So let me explain a bit more precise what I need…
I'm used to configurate lots of hardware Routers with Firewalls. Doing things like creating firewall rules, opening ports on specific protocols, WAN-to-LAN and LAN-to-WAN, NAT IP redirection, enabling SIP, content filtering, wireless accesspoints with encryption and MAC Address filtering, creating VPN tunnels, setting up Remote Desktop on Windows and Mac computers for Terminal Servers etc.
I'm also administrating FTP servers and NAS harddisks.
All that is always being configurated in a nice intuitive user interface via my web browser. Wheter it is a Router, NAS disk etc. THATS WHAT I WANT with the Firewall in Mac OS X. An "intuitive graphical user inteface" where I easily can configurate the Mac OS X firewall or a stand-alone firewall for that matter.
Yes I self use on my Mac Pro the Hanynet NoobProof firewall GUI right now.
But both the Hanynet firewall GUI's are crap. Lets face it!
They work yes! But the User Interface is NOT Mac OS X standard right!!!
If you pair the user interfaces with standard unser interfaces of a normal end-user Gateway Router with Firewall. Like ZyXEL, NetGear etc.
The Hanynet NoobProof don't have the feature to
choose ports on specific protocols.
With Apple FaceTime there are ports on both the
TCP and UDP protocols that has to be open for communication.
On the other side the Hanynet WaterRoof GUI
I know that it has the features to configurate ports on specific protocols but!
The User Interface is waaaaaaaay too complex and is anything else than intuitive!
I can't find ether head or tale in WaterRoof GUI!!! Completely Lawsy Interface. It is SO non Mac like!
(it needs a interface designer like myself)
I mean, "The Mac" and Mac OS X is all about doing things the "EASY, Nice and Intuitive Way" right!
I can't be that I'm the only one in the world that need a better and faster configuration of the Mac OS X firewall, can it?! There must be hundred thousands of other Mac OS X users with the same wish.
I know I'm a "designer", not a "programmer".
The only thing I program is HTML, CSS and DVD Video titles.
So with all due respect.
*** The question is…
Does anybody know a Firewall GUI or stand alone firewall for Mac OS X Snow Leopard/Lion that are easier than Hanynets????????????????
=========
If I was an Apple employed that delt with Mac OS X security.
I would make the Mac OS X firewall user interface different.
Top level choise could be: ON, OFF and CUSTOM.
So people with non knowledge of firewalls could just choose ON or OFF
to their liking. And leaving the choise for people that would like
to customize the firewall settings with the "Custom" button.
And there after a nice intuitive graphical user interface
to make all sorts of custom settings JUST like on a Gateway Router with built in firewall.
A firewall like that could not hurt anybody could it???!!!
It's MY Mac, I want to rule over MY firewall.
I like the Mac OS X very much, I think it is absolutely brilliant,
but the Firewall settings is NO GOOD for custom firewall configurations.
Apple has to pay attention to it, the sooner the better.
Please feel free to comment.

Application Firewall settings and OSX 10.5.2 Server

I recently upgraded our servers at work to 10.5 and then performed the upgrade to 10.5.2. Now I have a service that's having issues connecting to another computer and my thought is that it might be the new firewall that's causing the issue. However, when I went go change to the settings, I can't find the control for it as described.
I'm looking for it at System Preferences -> Security. I'm only seeing two tabs on this page, General and FileVault. I do not see a tab for Firewall anywhere.
Help would be appreciated.
Thanks

Hi Ian,
Go to http://www.apple.com/server/documentation/ and download the NetworkServices_Adminv10.5.pdf manual. Information on the Firewall and its configuration are in there. Most everything you need to know about running Leopard OS X Server is on that page. The rest is in these forums and at http://www.afp548.com and http://osx.topicdesk.com for starters.
Good luck with your new server software.

Firewall configuration between clusters

          We are planning our web infrastructure as follows:
          internet ----> firewall(1)+HD loadbalancer -----> Weblogic
          cluster (servlet/JSP) ----> firewall (2) ----> Weblogic
          cluster (EJBs)
          The reason we want to put a firewall between servlet clsuter
          and EJB cluster is that anything goes wrong in the front
          presentation cluster, our mission critical business cluster
          is not to be touched.
          Now, what are the requirement for the configuration of firewall
          2. I have the following question in mind:
          1:) I seem to remember reading on the document that we must
          bind the DNS name to the naming lookup directory, TRUE?
          2:) As this is a pure JAVA environment, I assume the communiation
          between servlet and EJBs will occcur through RMI. Does
          Weblogic use a specific port to listen to RMI request on
          server side (EJB cluster)? If so, how do I find out what
          it is?
          3:) Is it sufficient enough to just allow the above mentioned
          port open in my firewall 2 to enable the Serlvet/EJB
          connection?
          What if I have multiple Servlets talking to multiple EJBs
          at the same time? Do all these communication go through
          the same port?
          Thanks


Danny,
          > 1:) I seem to remember reading on the document that we must
          > bind the DNS name to the naming lookup directory, TRUE?
          In the document it spends 90% of the time talking about DNS. Needless to
          say, you typically don't have to make any DNS settings at all.
          > 2:) As this is a pure JAVA environment, I assume the communiation
          > between servlet and EJBs will occcur through RMI. Does

          > it is?
          If I understand correctly, Weblogic often uses RMI over T3 (their own RMI
          implemetation). That would use 7001 by default.
          > 3:) Is it sufficient enough to just allow the above mentioned
          > port open in my firewall 2 to enable the Serlvet/EJB

          Yes.
          Just remember, if your servlets can get through the firewall to your ejb
          servers, then so can anything else that gets there.

Solaris 10 Firewall configuration with a GUI application

Hello,
I am quite a novice regarding Solaris.
I have searched for hours on the web for a safe GUI application with which I can configure the
firewall on Solaris 10 05/2009 in order to surf the Internet. Unfortunately I have not found one but
lots of instructions instead on how to modify various config file setting, which I do not understand.
My Solaris books are also of no help.
Is there a precompiled GUI tool available similar to the one shipped with OpenSUSE's yast ?
I think such a tool would make Solaris much more attractive for non-sysadmins - also because of
its excellent hardware support that is superior to Linux.
Thank you,
Alexander

IPF studied in little chunks is really easy to manipulate.
Fortunately there is a doc that splits up IPF into little chunks with each new chunk building on all of the old chunks.
http://www.obfuscation.org/ipf/ipf-howto.txt
Then all you need to do is to create /etc/ipf/ipf.conf
and

Server Firewall Configuration

Hi.
I am trying to realise a custom ruleset for the Server System firewall.
I would like to know if there is a list of Protocols that are actively supported by the gui.
I have tried to introduce rules to the advanced interface in accordance with ipfw, ( or my interpretation of the gui understanding of ipfw but find that some of my rules are unacceptable.
A point of example is to set the protocol to other and introduce a rule relating to tun0, it seems the gui cannot configure this.
If possible i would like to come to an understanding with the gui.
At this point, it appears i have three options.
1. Bend my rulesets to accomodate gui ability.
2. Bypass the gui with sunsheild
3. Bypass the gui with a custom ruleset script.
written in ipfw 8.
Any comments on my understanding and what is considered to be the optimal way to go would be gratefully received.
Many thanks.
Mac OS X (10.4.3) Ipod; X Serve G5 Dual; G4 stuff;

In answer to myself....
Having spent a couple of days on this issue i have come to the following conclusions..
~ The firewall gui is better than i thought and allows me to do 90% of what i want to, but does take some getting used to. - especially as i am new to ipfw2
in order to understand what IPfw commands are supported you need to access man ipfw from the terminal.
This explains the syntax and helps understand the way the default firewall rules are configured.
~ I decided not to go down the Sunsheild / Other Bolt on interface, in reality they do not allow me to acheive any more, it just makes things a little easier to comprehend.
~ Writing shell scripts is not the solution (in my opinion).
Software updates could really screw things up, and that cannot happen.
i admit that i am surprised that the Mac does not fully support ipfw2 at terminal level. - but has its own syntax, to confuse the issue.
Although many Mac users seem to consider a firewall un-necessary, i can not subscribe to this.
My Conclusion.
The Mac Firewall is very good, but could be yet improved.
I still love my Xserve and it looks great.

IAS & Firewall configuration (NAT)

Hi,
We got an iAS instalation in which the Web Connector & the iAS separated by a firewall that's making NAT.
In our configuration we forward port 10818 in the firewall to port 10818 in the iAS machine, and we make a similar configuration with LDAP.
Apparently the Web-Connector is able to connect with the LDAP and the iAS, but we detect a latency of about 7-8 scnds, since the Web-Connector firstly tries to connect with the private-internal address of iAS.
Is this behavior the correct or is there any solution/patch in order to avoid this problem.
Thanks a lot,
David

Hey,
What is the network latency when you ping from webconnector m/c to appserver m/c. If that is also 7-8 secs then it is normal behaviour. If not check whether you have 389 ldap port is open. It seems that you are able to connect to ldap but what do you mean by " web connector firstly tries to connect with the private-internal address of iAS" .
Is iAS and weboconnector on a differenct subnet.

Proper firewall configuration?

Is there a plain English article anywhere that describes how to configure the firewall??? I have no idea of what is supposed to be on or off, what port #s to use, what the difference between TCP and UDP ports, whether I should block UDP or enable Stealth Mode, etc...
The Apple documentation is almost non-existant. The info in the "Trouble shooting revisited" thread doesn't correspond to the available options and is too cryptic.

Hi Clyde,
Pages 3 and 4 http://www.ralphjohnsuk.dsl.pipex.com/page3.html
Use the second item in the menu to see the link to page 4.
Many routers and modems here http://portforward.com/routers.htm with pics and explanations on which ports to open. Mostly it is the Port Forwarding method but some also have the Port Triggering options.
Many only list the Text chatting port and need the other 22 ports added for the UDP protocol as well.
The information in my pages is taken from this Apple Doc http://docs.info.apple.com/article.html?artnum=93208 and converted inot a more useable form (hopefully).
You should not use the "Block All UDP Traffic option in the Mac Firewall as iChat uses the UDP protocol.
UDP and TCP are internet protocols.
I have not tried the Stealth Mode.

Ftp - ftpd and firewall configuration for passive connections

I set up ftpd on my imac. Connecting and logging on work ok, but when I try to get a directory listing or xfer or send multiple commands it always locks up, i get a message "421 Service not available, remote server timed out. Connection closed" and I see that the ftpd process for that connection has terminated.
Turning the firewall completely off allows ftpd to work correctly, but I was under the impression that if I check the "FTP Access" box under services, the firewall should CORRECTLY self-configure to allow connections to ftpd. Opening ports 1024-65535 guarantees that ftpd will work with a client's passive connection, but is there a better way?
I tried opening 20 for the data connection and 21 for control, but unless I tell everyone to use an active connection, there is still a long wait before most ftp clients notice that passive isn't working and switch to an active connection, so I would like to avoid that also.

Hi, we use FTPd (with Pure FTPd Manager) on our internal server here. While I'm not a complete expert, I do know that we were able to get passive FTP working only after we got this setup properly.
The main reason we got this was for it's ability to set a default port range for passive FTP to work on. In Pure FTPd Manager, you go to Preferences/Settings and you will see the area to input your passive port range (we use 51000-51100).
Then you just need to forward those ports (on a router) to your FTP server, and/or open those ports on your server firewall.
It sounds like you already have ports 20-21 setup.
Hope this helps!

Question on firewall configuration

Hi
The above configuration is the sketch of my network with PIX firewall 515E. 200.2.xx.xx are the public IPs.
It has been configured that if someone through Internet access specific services like http
of 200.2.xx.xx is routed through to local address 192.168.0.240. Anyone can access
the sevice using the domain name or the public address 200.2.xx.xx. When it is in the LAN,
we can access the website using the domain name but not with the public IP address.
But accessing via local address is successful like http://192.168.0.240. Is there a way to re-route
the traffic to the LAN address if someone inside the LAN access the service using the public address?
Please help me.
Actually, I need to configure a server that will only use IP address. But both inside and outside users
should be allowed to access the service using the public IP address. So far, users have to use
public IP when they are at home and private IP when they are in the LAN. Thank you.

Hello Refg,
Unfortnately no, since commands needed were introduced in that version.
One of the commands used is same-security-traffic permit intra-interface applies to non-encrypted traffic after 7.2(1).

Global configuration of OSX

Hi,
Is there a way (without controlling preferences via an Xserve/OSX Server software) to globally set preferences for a client computer so that each account that logs in will have the same interface?
I'm configuring a lab of computers that will be bound to our AD domain. I need to set Dock applications and configure the Sidebar so that network shares aren't visible for all users logging in.
Can this be done globally while installing the system? I really need to hide the sidebar.
Thanks,
Alan

Not AFAIK, the decision of white and black lists is also user configured, not admin configured.
You probably want to do some blocking of those requests directly on your network devices.
