Firewall Blocking a Program? How to Allow Apps in Norton 360 and Windows
Is your firewall blocking a program from the internet? Years ago a friend’s new PC could open websites in Internet Explorer but not in Firefox. The culprit was Norton Internet Security’s firewall: at some point he had clicked the “recommended” Block option on a pop-up, and Firefox was silently cut off. The same thing still happens with Norton 360 and the built-in Windows firewall. Here’s how to find out if a firewall is blocking a program and how to allow it safely in 2026.
Quick answer: In Norton 360, open the app, go to Settings > Firewall > Program Control, find the program and change its access from Block to Allow (or Auto). In Windows 11, open Windows Security > Firewall & network protection > Allow an app through firewall, click Change settings, and tick the app for Private (and Public if needed). Only allow programs you trust.
Table of Contents
Signs a firewall is blocking a program
- One app can’t connect while others (like another browser) work fine.
- Errors such as “can’t reach the server”, “connection refused” or sign-in failures in just one app.
- Online games or video calls can’t connect to other players.
- It started right after you clicked a security pop-up or installed a security suite.
How to unblock a program in Norton 360
- Open Norton 360 from the system tray or Start menu.
- Click Settings, then Firewall.
- Open the Program Control tab.
- Find the program in the list. If it shows Block, change it to Allow or Auto.
- If the program isn’t listed, click Add and browse to its .exe file.
- Click Apply and restart the program.
Also check the Traffic Rules tab for a rule you might have created, and make sure “Block all network traffic” isn’t turned on. Menu names can differ slightly between Norton versions; see Norton Support (external site) if you can’t find them.
How to allow an app through Windows Firewall
- Open Windows Security (search for it in Start).
- Click Firewall & network protection, then Allow an app through firewall.
- Click Change settings (needs admin rights).
- Find the app and tick Private. Tick Public only if you need it on public Wi-Fi.
- If it’s not listed, click Allow another app and browse to it.
- Click OK.
Note that if Norton or another third-party firewall is installed, it usually replaces Windows Firewall, so make the change there instead.
Other security suites
- McAfee, Bitdefender, Kaspersky, ESET: look for Firewall > Application rules or Program control.
- Mac: System Settings > Network > Firewall > Options, then add the app and set it to allow incoming connections.
Still blocked?
- Temporarily turn the firewall off for a minute to confirm it’s the cause, then turn it back on and fix the rule.
- Check antivirus “web protection” or browser extensions, which can block sites separately from the firewall.
- Check your router or a parental control app.
- Make sure you’re running the latest version of the program; updates change the file path and can trigger a new block.
If a slow or blocked connection affects every app, see our fixes for faster broadband. Blocked websites rather than programs? Here’s how to unblock websites.
FAQ
Is it safe to allow a program through the firewall?
Yes, if you trust the program and downloaded it from the official source. Never allow unknown programs.
Do I need Norton’s firewall if Windows has one?
Windows Defender Firewall is enough for most home users. Third-party suites add extra controls and alerts.
Why does my firewall keep asking about the same program?
Each update can change the program file. Allow it again, or set it to Auto in Program Control.

When i click personal firewall it doesnt show configure.
I have tried to post a response here and each time I try it refreshes the screen or gives an error. Can the writer possibly look into the reason there is a problem?
Firefox still didn’t work. It said proxy server refusing connections. It was already permited by Norton Internet Security.
This is probably not the best solution. You can’t permit all the traffic

Excellent step-by-step explanation of how to unblock accesses that have been blocked by mistake in Norton Internet Security
was not able to access “www.google.com” from desktop which is installed with “Norton Internet Security” – have no problem accessing other sites. Any idea what to look out in the Norton Internet Security Setting? Thanks
All the proxies that you get when you search for them is blocked, or dont allow you to log into myspace.
Is there any other way to get past the schools blocking system?
You beauty! Thanks a bunch for this – I thought I’d knackered my computer but then I found your site.
Cheers!
how do i get past symantec i dont care about myspace i need games what do i do
I wish i could use myspace at school so school can be more exciting
The Myspace problem is pointless. Schools are starting to ban proxies and such as well. If we want to use myspace and messengers, we need to start figuring out new ways to get past firewalls.
Stop begging people to find it for you and learn how to hack on your own.

Thanks. This tip did the trick. FF back up & running
I think my problem occurred as a result of eye-hand (or brain-hand) coordination with an annoying pop-up’s “recommended action” to block access and an OK of “always block”.
Lesson learned.
how can i unblock ” myspace” from the schools computer?
Thank you sooo much. Great Job. I needed this a lot. YOU =
Thank you so much!! I was going crazy trying to figure out how to change the security level for Itunes.
asr: Thanks for your post. your solution solved my similar firefox blocking problem. Thanks for detailed screen shots. you Rock :-)
Thank you so much for your help. I work for a local ISP and was working with a customer who couldn’t get his Yahoo to work. Was his norton firewall. The instructions here were perfect. Thanks so much :)
This didn’t work for me. I changed all the settings as described. Still Firefox was blocked. What did work was changing the security level of the firewall from medium to low. Then Firefox could access the Internet. What I want to know is why does IE an Opera work with the standard default settings. Only Firefox has a problem.
AWESOME!!! This thing may have just helped me get laid! Tech support rules….
