Want to use server software on an Android but seems like Vodafone doesn't allow incoming connections. I use the recommended APN, and it times out immediately. If I change to the APN internet it works is to slow and I get 25% package loss. That s....! Anybody knows a workaround or better a solution? Thought the Android should have an open APN configured by default as it doesn't makes sence if you can get server software from the apps store and not operate it :-(

Having software that work as a server available doesn't mean the operator has to support incoming connections.

Check this post for a description of each Vodafone APN and security involved.

Also moved this to the correct forum.

thanks for that. I tried the internet APN as mentioned but massive package loss. Btw 11and25%. So the apps were struggling. If I use same apps on but mobile initiated I only have 1-4% package loss. Seems quite different.

Hi john,

thanks, have tried but doesn't work neither. :-(
Wonder how google agree on that. You can purchase apps in their store but not operate them ..... doesn't make sense to me. Might bring my Android back to the store. Very frustrated with Vodafone.
Thanks for all the help.

Android uses iptables to limit inbound connections from the web:

Being a always-connected device this is neccessory, nobody want's to get put off-guard with leaving things like SSH open on it :P

Just click Here for something that happened with Jailbroken iPhones not too long ago, A dutch hacker decided to break into some iPhones in Holland and pretty much change the home-screen image.

Stop complaining about your phone, if you knew your way around linux or could use the Android Market you would be able to find a config file for iptables to edit these restrictions yourself, or find a GUI in the Android Market to do it for you. It's not Vodafone's fault, it's on every linux device pretty much (including the iPhone and many servers around the world) to prevent Bad People getting in and messing around.

Then again, I had sometimes up and running, it's basically a Dell Mini 9 running Ubuntu Linux being used as a "Spy Camera" on the Vodafone Network, it's possible, and that's using the APN too (except this domain is no-longer up)

The server software works fine on a LAN. I use "SwiFTP" to download / upload files via the FTP server running on my phone from PCs on my LAN at home and at work.  

I never expected Vodafone to open port 2121 on their entire 3G network for my sole use for incoming traffic. (SwiFTP is hard-coded for port 2121) Based on Mike's answer it may well be that the phone itself blocks incoming from the Internet. That would make good sense from a security perspective. 

What server are you trying to run?
