Ncat Level 1 Level 1 (0 points)
Hi,
I'm having some problems using my iPad through a corporate proxy. I have my Wi-Fi configured up correctly and have set the proxy settings using manual settings. This all works fine and I can access none secure services.

However, when I try to connect to anything other than HTTP it won't connect. Is there an option to 'use the same proxy for all protocols' as in windows? Good example is - I have my iPad and work laptop (windows) connected to the same Wi-Fi with the same proxy. I can access these discussions on both devices - until I come to login - I cannot login using the iPad but I can on the laptop.

Any help would be much appreciated.

Thanks
Neil

iPad, iPhone OS 3.1.3

    I am also having the same problem but cannot find anyone who can answer my question. Did you find anything out about this issue?

    Nothing yet, I've read through the enterprise deployment stuff from apple and it doesn't cover this.

    we are also facing same problem, very annoying.

    We have a proxy server set up and I've configured the iPad network settings to use the server, port and authentication settings given to me by the network admin. The only thing I can get to work is safari. No other apps will connect. Are they using different ports? If so, what is the point of having manual proxy settings on the iPad?

    C'mon apple - if you seriously expect us to use this thing for business then you need to fix this.

    Yep the problem is that other protocols use different default ports and unless you can overide these so they all use the same proxy port you are restricted as to which services to can access. If you do a new install deployment following Apple's guidelines for Enterprise deployment then I think you can get everything to work by forcing policies down to the iPad, and configuring the reverse proxy to translate port settings. Here is the link to the Enterprise Deployment Guide if anyone needs it - http://images.apple.com/ipad/business/pdf/iPadDeploymentScenarios.pdf

    That doesn't help though when you have an existing network which cannot be changed.

    I found this information on our firewall providers site.
    http://kb.k12usa.com/Knowledgebase/Proxy-Setup-for-Apple-iPad

    As of 10/13/2010, only Safari and the App Store will use the proxy settings to connect.  All other apps will try to connect to the Internet directly.  If you want these apps to work, you'll need to make firewall rules allowing access to the servers needed to make them work.  Apple is currently aware of this limitation, and is working to resolve the issue in a future version of iOS.

    I hope this spreads some light on things. I don't know why this information isn't more readily available.

    I'm not quite sure that all other apps except for AppStore and safari try to default to the Internet ignoring the proxy settings. I have a few apps that have been dependent on the proxy setting in order to work to date. Curiously though, this has stopped working reliably for me after updating to 4.3 this week. So I did some investigation. Our corporate proxy is a Microsoft ISA server and checking the logs on there after repeated failed efforts to get to either http or https sites revealed that the proxy was not getting presented with the user credentials from the iPad. The proxy was getting no username / password and as a result dropping the requests. Very occasionally, it would present the credentials and pass the traffic but it's intermittent to say the least.

    Previously this problem impacted me only on https traffic and http traffic worked fine. But this week, both protocols have become an issue (immediately after the 4.3 upgrade). This affects both the iPad and iPhone when connected through the proxy. It's also relevant only to proxy connections that require authentication. I have been able to use a different proxy through an alternate part of the network that doesn't require authentication and it works fine. This is how I am currently getting around the issue.

    My interpretation of this problem is that IOS device functionality with proxies that require authentication is just plain broken. And it seems to be "more" broken for me on 4.3 than it did on 4.2 as where I was previously able to get most http access through the proxy ok (but never https), now I can't get other.

    I don't know if this is the same thing, but I work as an ICT technician in a secondary school and we have had the same problem with a teacher using a macbook. She could access http sites through our proxy server but not https, particularly an online banking page and her hotmail e-mail.

    I configured the https proxy on her macbook using the same details as the http proxy, same name same port.

    This didn't work. It however came down to the fact that I named the server, when I substituted the IP address of the proxy server instead, it worked correctly and she could access https sites just as easily.

    If iPADs have the same basic settings as MacOS equipped macbooks and imacs then if there's a similar setting for an https proxy it might need setting to get https to work.

    hey maverick_ghost

     

    i use college lan which uses http proxy servers to get me online. same issue on my macbookpro. but i can access everything from the browsers, except the sites they blocked to prevent heavy traffic flow (youtube, video-plugins n stuff). i can even use itunes store, and software update connects too. but all the other apps: mail, ichat, iphoto, garage band, nothing connects to the net. though all the other third party apps are again able to. i would have said my college is blocking some connection, but then even the third party ones should have gotten blocked.

     

    any views on this?

     

    thanks
