Changing firewall settings

In the screenshot below, the panel on the left is from my System Information app. The panel on the right is what is shown in Firewall > Advanced.
As you can see, there's some apps that have connections 'alllowed' on the left but which do not show up in the 'Advanced' listing of programs (I only highlighted two, but there's quite a few others).
My question: how do I change the firewall permissions for those apps that I don't want to give access to but which aren't in the Firewall listing?
TIA

I have the same question. Firewall is set to block ALL ports, yet leaves HTTP(80), HTTPS(443) and SSH(22) open. I have no webserver running, nor sshd. But I would think it should block these ports!! RUn "GMC's shields up and they are wide open.
More and more I am getting frustrated with Max OS X. Apple provides no easy way to "Refresh" a package.
ie. If this were Fedora, Susi, etc. you can simply repair by grabbing the code for the firewall and refreshing it via wget(). But this is a mac, and you have to make it look like Linux first using one of the methods like "Fink"... I am so tired of this, I need to replace my older Macbook. Was looking at another $3000 for a new MBP. I think I will buy a Dell with quad i7, 16GB ram for $350, and run a hypervisor and switch between Solaris and CENTOS so I have control. I don't think I will really miss COCO that much. Been a Unix guy all my life. Went from PC to Mac when I just "Need to get it done and it has to work". Well security seems to SUCK on Mac OS X, so I have had it. FOrget an Iphone5 I will go with a Galaxy III and android. It is a painful change, but I am so tired of these issues. I went from one MS mess to an APPLE mess. I don't want to have to mess with the firewall, but I don't want my system exposed either, so I am forced to do so!! Heck, might as well run Linux and control the firewall. Actually better support and interfaces... no more iptables, nice gui's out there...
GO from Bill Gates CRAP to Steve Jobs Crap. Paying more for underpowered Mac hardware? It just isn't worth it anymore IMHO.
Also, support? I don't see any reponses to thie persons question from 2011!!
No support.

How do I change firewall settings?

I have been having trouble for months logging into a website that I had zero problems with under my last provider (and am having no problems accessing using my laptop's Wi-Fi). I've checked out just about every other possiblie cause and a friend thought it might be the firewall settings on my router (I have FIOS and the MI424WR Rev. F) and suggested I take a look at the settings and see what happens if I set them lower.
Said friend, didn't however, tell me how to do that. How do I get to the firewall settings in order to do an experiment and see if it's the firewall that's causing my headaches? I'm getting desperate.

Or how about a Bogon filter due to his current IP address now that he is on Verizon? The OP doesn't provide any info on messages he may be getting, so this is just a guess.

How do I change firewall settings modified by VPN server?

(This actually happened while I was running Lion, but seems to be the same problem under Mountain Lion)
I installed Check Point Software Technologies Ltd. Endpoint Security VPN for Mac E75 VPN client on my iMac to access my employer's network. It worked, but after I logged onto my employer's network, I lost contact to both my Time Capsule and Airport Express (Airport Utility stops "seeing" them, even though I am still connected over wi-fi to the internet through the airport router in the Time Capsule), and iTunes stopped "seeing" my iPad and iPhone.
I looked on Check Point's support pages and saw this "Known Limitation":
Issue ID: 00885275
After Endpoint Security VPN is installed and a client is connected to the gateway, automatic sync with Time Capsule and iPhone Wi-Fi sync might not work correctly.
This can happen because of a restrictive Desktop Policy.
To resolve this issue, allow these services in the "Inbound rules" of the Desktop Policy:
SSDP: UDP, port 1900.
mDns: UDP, port 5353.
Further research in the Endpoint Security VPN for Mac E75 Administration Guide told me this about "Desktop Policy":
The Desktop Firewall
Endpoint Security VPN enforces a Desktop Security Policy on remote clients. You define the Desktop Security Policy in a Rule Base. Rules can be assigned to specific user groups, to customize a policy for different needs.
Important - Before you begin to create a Desktop Security Policy, you must enable the Policy Server feature on the gateway.
Endpoint Security VPN downloads the first policy from the gateway. It looks for and downloads new policies every time it connects or on re-authentication.
When Endpoint Security VPN makes a VPN connection, it connects to the gateway and downloads its policy. Endpoint Security VPN enforces the policy: accepts, encrypts, or drops connections, depending on their source, destination, and service.
So (I think) what happened is when I logged on to my employer's network, it re-configured my firewall to limit my network connections resulting in the above-described problems.
Logging out did not change anything. Uninstalling the VPN client did not change anything. It looks like the changes "enforced" by the VPN client are persistent, and can only be changed "manually."
I doubt I will be able to prevail upon my employer to change its desktop policy. So I'm ready to bail on using the VPN client, but how do I reverse the changes my employer's "desktop policy" made?
The System Preferences Firewall options seem kind of high level. I would note that iTunes looks like it is open to all connections.
Thoughts? HELP.

It is not something I have played with.. but I would turn off the Mac's firewall and see if that fixed the problem.. the firewall of the Mac is helping your security.. but the main security is actually the NAT router in the TC. It is extremely difficult to break NAT routing.. It is effectively a firewall itself. So turning off the firewall in the Mac is not a biggie. The reason I want you to do that even if just for a few minutes.. and perhaps turn it off and reboot the computer to make sure the rules have stopped being applied.. is to see if the firewall is actually the culprit.
What I am reading from what you have posted is the vpn client itself is the software blocking connections. And I doubt a third party software would change rules to the internal firewall.. but i am guessing.
Once you have tested it.. if the firewall off fixes it.. then you will need to hunt around.. perhaps in a TM backup for the actual file that is altered that contains the rules.. I have not looked.. and don't use firewall on the end client anyway as I have a firewall rated router.
If the firewall off does not fix the problem.. which is what I suspect. Did you use the uninstall software correctly and did it give any error messages??
Go to the activity monitor and check all the running processes.. anything there that is named after the vpn.. try to quit. See if you can stop the process.. If the issue is major.. and the process won't quit see if the Checkpoint support can help or google their knowledge base for info on how to get back to normal operations.

Change firewall settings via terminal

hi,
I've got an old Powerbook that has a broken screen. Luckily I can access all my files and also ssh into the computer. Is it possible to open the firewall port 7001 via the command-line so I can use something like Desktop Transporter?
Thanks for any reply.
Gert

Yes, of course. First question, though: why not take the firewall down altogether?
The thing is, ipfw uses sets of rules, and the order is significant, so it's not just adding a rule, it's where you add the rule. So, for example, if I see:
<pre>
$ sudo ipfw list
02000 allow ip from any to any via lo*
02010 deny ip from 127.0.0.0/8 to any in
02020 deny ip from any to 127.0.0.0/8 in
02030 deny ip from 224.0.0.0/3 to any in
02040 deny tcp from any to 224.0.0.0/3 in
02050 allow tcp from any to any out
02060 allow tcp from any to any established
02065 allow tcp from any to any frag
02070 allow tcp from any to any dst-port 22 in
02080 allow tcp from any to any dst-port 548 in
02090 allow tcp from any to any dst-port 427 in
02100 allow tcp from any to any dst-port 80 in
02110 allow tcp from any to any dst-port 427 in
02120 allow tcp from any to any dst-port 443 in
02130 allow tcp from any to any dst-port 21 in
02140 allow tcp from any to any dst-port 139 in
12190 deny tcp from any to any
65535 allow ip from any to any
</pre>
Obviously, you need to add your rule before the blanket deny rule, so enter:
$ sudo ipfw add 02150 allow tcp from any to any dst-port 7001 in
Or you could do a rule like:
$ sudo ipfw add 02005 allow ip from ME to any in
Where ME is your IP address (or MAC yo:ur:ma:ca:dd:re:ss) to allow all access from your computer. Unwise because both are easily spoofed, but you can delete it as soon as you're done:
$sudo ipfw delete 02005

How do I change my firewall settings to allow Spotify?

I get a message pop up that says.... A firewall may be blocking Spotify. Please update your firewall to allow Spotify (error 101)
Please help I am so terrible with anything other then the basics.
I found my firewall settings but I could only figure out how to turn them on and off. This did not help.
I need it explained to me in the most simpilist of ways.
Thank you

Please read this whole message before doing anything.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

It's not letting me change the firewall settings.

I have a odd problem. It's not letting me change my firewall settings. The settings are locked by default, when I click on the little lock image in the bottom it does not prompt me for the password, it says "authenticating" for about 2 seconds, and then the "Click the lock to make changed" text appears again. I don't know what to do...

I only have one account and I don't know how I could log into it more than once at the same time...
My signature is not correct... I have the latest 10.6.1.
Would it be possible to change the firewall settings in terminal?

How to change the firewall settings to provide remorte access to oracle 10g

dear all
I have created the oracle 10g database and it is working properly...but I cant loging with thedata base remotely when the host's firewall is on..when it is off I can connect with the database remotely..how can I change the firewall settings in this case

You need to configure your firewall to allow traffic on the ports listed in ORACLE_HOME\install\portlist.ini.
You do not need to allow all of the ports, just the ports you want to allow traffic. For example if you are not using iSQL Plus you do not have to open port 5560 or the range 5560–5579.
You can find a description of the ports at the following link.

Unable to reach Adobe servers, Please check firewall settings and try again

I have been a creative cloud customer since it started and I've never experienced such buggy software as the app manager. The customer experience is just shocking and I wish Adobe would just offer direct downloads for the software we need rather than use the app manager.
I'm currently trying to install the latest versions of the programs but the app manager keeps showing "Unable to reach Adobe servers, Please check firewall settings and try again in a few minutes".
I do not have any firewalls on my network.
I've uninstalled all previous versions of the applications.
The app manager will download a few % and then the message appears again. I click retry and it downloads another few % before showing the message again. I keep doing this until the program is fully downloaded and installed which take hours. Because I am able to eventually download the app, the error should be anything to do with my setup or internet connection as I've never had this issue before when installing adobe products.
Is there a way we can bypass the app manager and install the programs directly? This is getting very annoying and I just need my apps to install without wasting days clicking the retry button.

I'm having the exact same problem. Photoshop is stuck at 0%.
Have the links for direct download changed? When I went to http://prodesigntools.com/adobe-cc-direct-download-links.htmland then scrolled down the page to:
Photoshop CC 2014 (64-bit)
740 MB
File 2
801 MB
File 1
and then clicked on File 1 and File 2, I reached a page that says "You don't have permission to access "http://trials3.adobe.com/AdobeProducts/PHSP/15/win64/Photoshop_15_LS20_win64.7z?" on this server."

How do I set my firewall settings in Avasti to allow communications between my HP 8600 and my comput

How do I set my firewall settings in Avasti to allow communications between my HP 8600 and my computer

Something to Consider:
If you are talking about "Avast!" Security Software, either the free or the paid version, the following may apply to you:
There are three main levels of Security in the Avast! software: Home, Work, and Public
Home is the setting many people use when "at home", that is, connected to the home network. The home network is sometimes defined as the "192.168" network: these are the computers and printers that you have and use in your home environment. The network is (most usually) private and (should be) secured with with a passphrase at your router. The Avast! Software sees the "Home" network as a "safe" environment: devices connected within the "Home" network are allowed to "talk" (communicate) with one another without undue restrictions.
Work is the next setting. The software places some restrictions on this level of communication. Home users can certainly use this setting -- in many (most) cases, the "Work" setting is a solution that provides for communication and a bit more security for the home network and its devices.
Public is the strictest setting and is meant to keep your computer safe in a public place: the library, coffee shop, on a street corner. Outside "prying eyes" are prevented from peeping and outside communications are restricted.
If you have set (or left) your Avast! software set to Public, or even Work (and you do not know how to handle the restrictions), then you may have simply locked out the communication between the printer and the computer(s) on your home network.
Open your Avast! Software and set the security level to either "Home" or "Work".
You can find out more about how to use the software settings at the Avast! website.
Advanced Users Only - You will know if you changed the Rules... this is not something one does by accident.
If you have changed the rules within the settings, you may have locked yourself out. Make sure you have both "in" and "out" traffic settings adjusted correctly for each rule you change / adapt / add.
Kind Regards,
Dragon-Fur

Can't change firewall rules via preferences pane

When I select the Sharing preferences and switch to "Firewall", I get the following error (in German): "Sie können die Firewall-Einstellungen nicht ändern, da beim Lesen der Einstellungen von Ihrem System ein Fehler aufgetreten is", which actually means something like "You can't change your firewall settings because an error occured while reading your settings".
The error doesn't go away even after rebooting.

I assume you have specified german as your default language, because if you haven't then german error is quite odd.
Anyway, have you installed any other firewall software? Something has probably caused your firewall settings to either disappear or to change in a way that mac os x cannot read them.

10.5.1 Firewall Settings

The firewall settings have changed in 10.5.1. I wasn't using the firewall at all, but wanted to and wanted to know which setting was the best for my meager needs. I'm just a guy with an iMac with no wireless and no network, just a direct connection via ethernet to my DSL modem. What setting would you guys recommend? "Allow All" or "Allow Essential"? And if I do Essential will that slow anything down like web browsing or anything else?

Leopard "stealth" is for squat. I just switched from a failing motorola router to the airport extreme with the extra ethernet ports in back. The moto had a firewall and a stealth button.
https://www.grc.com/x/ne.dll?bh0bkyd2 scans your computer and is quite handy.
With the moto router and no mac firewall / stealth enabled, every square was green (stealthed), I was completely invisible. Shields Up, that link, called that an uncommon and very good situation.
With the airport extreme and mac's firewall enabled for essential services and stealth selected, I've got 7 stealthed ports, and 1,048 ports reporting back to the test as closed, and none open. No change from no fire wall, no stealth in preferences/security/firewall. My computer acknowledges itself to outside probes now. Not the best state of affairs.
I don't see anywhere in the airport utility where one can enable a firewall upstream from the computer. It's nice with the AE that everything plays together easily, but as for stealth.... squatola. Anybody can see you, so use modern encryption, like a previous reply said; WPA2/WPA2-Personal.
Maybe X.5.2 will beef up the security a little. Maybe X.5.2 will fix iCal's custom repeating event no show bug too. Doubt it though.
Anyway, Mac still rules. All your bases are belong to us.
