[Q] Android issues with a many-to-one NAT (company wifi) - Android Q&A, Help & Troubleshooting

Hi guys,
My company has recently opened up an internal wifi network for mobile devices. Of course they started with Apple and have finally allowed Android devices as well.
However there seems to be an issue. Like many big companies, we have a "many-to-one" NAT arrangement. This appears to be fine for Apple as the Apple users can access all functions like iTunes, AppStore, mail apps, etc.
But the Android users cannot. Web browsing is fine - but anything through the Gmail app, Google Play Marketplace, weather widgets, all fails and has "no connection".
Speaking to the team managing our mobile device access, they said they think it's to do with Android and how it works with a "many-to-one" NAT setup as the Apple devices run through the same network without issue.
Is anyone familiar with this? Is there something in Android or how it communicates outward? If there's anything anyone can tell me, it would help as I'd like to get this solved. I don't see why Android would behave diff to iOS in this case.

Limiting Andriod

Hello Everyone,
The company I work for is currently in the process of buying a set of the Motorola Admiral PTT (Push to Talk) phones from sprint for our employees. However we don't want them using the phones for personal use. So is there a way to block them from accessing the market (play store) or to block the installation of apps. Essentially, does android have any administrative features like what I just suggested.
Also, is there a way to block the internet browser. We don't want to turn off the internet but to prevent them from browsing the internet on the phone but still have access to other internet using apps like google maps or the gps navigation.
Thanks for any help,
Mike

Are there any ROMs with ability to block app installs for administrative purposes?

Hello there,
Short story - Looking for a Custom ROM with the ability to control what applications can be installed on an Android device or preferably to ask for an administrator password prior to installing, much like in Administered desktop systems. This is to be used on a large number of company-owned tablets
Thank you for any help or suggestions

Long Story - The company i work for (a large travel & tour agency) is investigating the possibility of providing Tour Bus drivers with Android tablets, which will be used for filling out and submiting (via mobile data) a number of different types of forms
Since the tablets will be connected to the internet via 3G/4G, any downloaded apps will cause data charges by the ISP. This is a major issue as the Tour Bus fleet consists of over 300 vehicles and drivers
For this reason, we were trying to find an app which would control what a user installs on an android device, but from what we have researched, this level of control is not available for Apps, for security reasons (such as malware)
Custom firmware seems to be the only option, if such a firmware exists.
Thank you for any help or suggestions
No dont exist but you can configure the pasaword in google play settings
Sent from my GT-S5830 using XDA
Use password to block or secure those app that can download things
Eg: mail, market, browser, file explorer, USB storage.. etc...
PM me if you need more detail... already have an idea.

[Q] IOS like restrictions for android (restricted profiles suck)

Is there an app available which provides similar features to ios restrictions, such as being able to prevent changes to accounts and contacts, meaning for apps such as hangouts or messenger i can prevent my brother from only contacting existing contacts and prevent him from adding random people (hes autistic...) Im currently using Norton parental controls and this allows me to block certain websites and send me usage reports, however i would like for him to be able to actually contact his family on the tablet, however being able to add people is a big no-no as he can become abusive to people. I managed this perfectly fine on his Ipod as within Ios restrictions you can simply turn on the option to prevent changes to accounts...
I'am quite an advanced android user and i cant seem to find a way to do this... i also cant believe people are praising the restricted profiles in android 4.4.2... i think it is awful only allowing you to block apps... there are numerous apps available to do this anyway.
Another issue i have is with the play store not asking for a password for apps even though this option is selected in 4.4.2. I know this is a reported issue as i have found a forum on the issue however no one had a solution.
Any help would be appreciated

google-ectomy, possible?

Hi all.
I have a rooted phone that is used strictly in wifi mode and only needs to be able to run 4 or 5 standard aps, a couple of optional aps, plus the aps that support rooted phones and enhanced power management. I don't want google-anything on it, and I am not kidding. My prime concern is battery life, I hope to be able to run my phone for 3 to 4 days (or more) between charges, so deleting all fluff aps and crapware is important, as is underclocking it and getting rid of google. I also want to stop updating of the operating system and installed software by google.
I hope to do a hardware mod to remove power from the cell band rf transceiver. Despite it being turned off in the phone using software, I am detecting occasional transmissions from the cell band transmitter. Hardware mods are not a problem for me, I'm a retired EE, who specialized in RF design.
I need to know if it's possible for the phone to function if gmail, google+, google search, chrome, google calendar and google-whatever are exhorsized (uninstalled)? Yes, I also want to give the playstore the boot, to prevent excessive battery drain (and, yes, I do realize downloading aps will be slightly more difficult without the playstore).
For those who might be interested, the phone is used as a wifi phone for the home based Ooma telephone service. I also might like to run a mini bittorrent server. It seems to me that the android community could use bittorrent in place of the playstore, thus making it easier for others to give google and google playstore the boot
I love this forum, and want to thank all those that support and administer it.
Aloha,
A

There are threads all over the place trying to do this. Google is deeply ingrained into all the apks used by the os. You will be very hard pressed to find away to remove them completely and still have things work right.
I agree that security is an illusion. I dumped Microshaft in 2013 in order to improve my security and privacy.
However, the android operating system is supposed to be open source, so it should be possible to de-google-ize it IF someone knows how to edit and recompile the android OS.
I was merely asking if anyone knew of a way to give google the boot, even if it came down to paying someone to compile a custom rom.
The loss of google playstore is not a consideration, neither is a monetary forfeiture (any programmers out there?).
I'm curious, is it possible to gag google so it can't connect to the outside world (with a firewall)? We used to do this in XP to prevent Bill's Internet Explorer from downloading updates.
Are any of the custom roms currently available able to run without google-anything??
Is there any hope, or is it truly hopeless? If a custom rom that gave google the boot was available, how many would pay a small fee to have it? Just curious??!!
TY

There is one project that is working on removing Google completely in the forums. A search will find it for you. There are some issues that I don't recall if they could find a way around or fix. You could give that a shot.

[APP] please recommend substitution of app: network log

Hey guys, I've been seeking an alternate of Network Log (you can find it on Google Play Store) for quite a while but with no luck, so come out to ask if anyone knows one suitable for me .
I have to say Network Log is almost worthy for purchasing (although it is not a paid app), considering the job it's done in categorizing by protocols, by apps, displaying packets by size and time, graphing as a timeline, and that made it an excellent choice for analyzing apps consuming data and draining battery, but unfortunately the app owner doesn't respond to bug summit or emails.
The thing is, Network Log no longer works after Android 6.0, while others in the market relies on system-built-in VPN function to capture data, which is not suitbale for people like me in China using proxies to reach out to world .
So if anyone knows apps that can capture packets (not necessarily able to decrypt contents) and display by apps, just to make it easy to let me see the amounts and frequency Android apps uses the Internet, I‘ll be thankful that you recommend them to me (again it cannot be using Android VPN function since Shadowsocks is already using VPN, so I think the app maybe require root permission but I'm OK)
check...
will somebody know that???
