How do I turn off firewall on iPhone?

Is there a firewall for iPhone?

I have read that on certain iPhone models there is a firewall installed called IPSec on the iPhones.

Is this true? What about other iPhone models. What iPhone model has the firewall and if there are other iOS devices that have this feature. Could I run an email server or a webserver on my iphone? Any ideas?

Check out this Apple documentation. It lists a couple of ways you can be notified of changes that occur. One is that an iOS device might be updated, meaning that they could install a new ios version.

If you want to have a server for your iphone, I'd recommend a web server like MAMP (on a Mac) or WAMP (for Windows). They will install and manage the server, and you'll be able to access it from your iPhone over 3G. It's definitely possible to install a server on your iphone, but you're going to need a jailbroken phone and knowledge of iOS and the development tools. You would have to put some kind of webserver like MAMP up to serve up files via its built in local network and the web.

How do I use NoRoot Firewall on my iPhone?

I've just used my iPhone 3G for the first time.

Previously I had it set up as a free-roam phone, so the sim cards were turned off when they were not in use. So how do I get around the network operator's firewall? Any suggestions appreciated.

If you don't trust the mobile network operators then you are running at least slightly increased risk of having your mobile phone (or other networked equipment like computer, printer, router etc.) used to access the internet. To my mind this is not acceptable.

How are they 'stealing' our money then? It was my idea to take a UK mobile SIM card from O2 and make my iPhone pay for the data allowance through that - that was an additional charge on my phone bill too. The mobile operators get their customers to take out service plans and pay for them by having "unlimited" data. Your tariff may allow only limited use which will eat into your monthly allowance. That's fine in most cases as it means you have access to the internet 24x7 for calls as well as for browsing. In any case it makes no sense to charge for a data allowance on a limited use device that you can't take anywhere. If, as the majority seem to be doing, they still use it for "roaming" then they are not using it for anything else except to make sure that if you send an email or browse the internet you use more than your limited data allowance.

Now I'm glad you brought it up as you've obviously paid more attention. I didn't see it as there was any point in paying extra to avoid being charged for roaming data - but what I don't understand is why the mobiles don't put the SIM card in a data pack if they intend you to be roaming off it. Why bother with the monthly tariff if they don't let you use your mobile data as it was intended and to give you more value out of the 100 you spend every month? This is what I did; I bought my iPhone 3G at full price from a shop instead of through the mobile operator. In a data pack, you pay a little extra for the data package plus an allowance to use it overseas which works out at half the price that you would pay through a mobile operator abroad plus the added expense of the premium rate call (which might be over 30p/minute).

Is NoRoot Firewall good?

I have a firewall that I like but it has this issue - it can't let me access anything without the login, any ideas on how to fix it?

And the reason it was set up was I was unable to access certain files that were created by Adobe Dreamweaver and when I got home I just clicked on connect without thinking to the firewall. Then later on I was able to access them.

I also did a quick search for a tutorial on how to set it up and I found a few things but nothing that I can follow through with that would help me out in the future. I don't think the firewall could be set up to make you accessible to anything, especially without the login, but I'm not sure. It can be, all you have to do is change the permissions on a folder. I used to have a windows firewall on my PC that would allow me to access everything on my PC, even though it had a login. I'm pretty sure a linux firewall would work the same way.

The question is whether you want it to do that or not. If it's set up to do that, then if you've set it to auto-login, then when you connect, your session will be logged in automatically, so as long as you're connected when the login screen appears, it won't give you a login prompt.

You could remove the login screen, which is what I do if I use firewalls like the built-in Windows 7 firewall. It was a feature from previous versions of Ubuntu - it's not there anymore (and should be removed from new installations).
