Peer to Peer communication on Android - General Topics

With personal computers like Android smart phones as powerful as they are, why are we always communicating through third party servers? Why is it necessary to have everything run through DUO parsed by Google? Why not communicate Peer to Peer? For example, LinPhone can call direct by setting "domain" to the remote IP - or better, the dynamic DNS entry. A VPN server could be configured to accept connections from friends with the right credentials. The direct connection will have less latency. Is anyone else doing this?

Torrent are the best example of peer to peer connection. Intranet and LAN are also make faster peer to peer connection.

I was thinking the same about torrent...

CSICO VPN Client

Is there away to install CISCO VPN Client on the universal device? instead of using MS client which I don't trust it as everyone does
If there's away please let me know how and where I can download the .cab file.
try this

I use this one (connection to a Cisco PIX):

you can also try SSL vpn (web vpn) or anyconnect client.
What's wrong with the integrated VPN client
The integrated VPN client in Windows Mobile 6/6.1 is a standards based client, I don't know why you wouldn't want to use it? I currently have Cisco IOS Routers & PIX Firewalls configured to work with the integrated VPN client in Windows 2000/XP/2003/Vista as well as Windows Mobile 6/6.1. I have disabled the PPTP stuff on the Cisco devices and only use the L2TP/IPSec with 3DES but it all works perfectly.
It took a while getting it working effortlessly but it does now Setup on the Client side is simple and easily supported - no worrying about 3rd party apps, I can't complain about any of it (not now anyway, at the time of testing and getting it all working might have been a different story.....).
Plus Cisco don't have a Windows Mobile VPN Client?

I'm using it exactly the same way you just mentioned above, but when I look to iPhone comes with CISCO VPN client built-in so I suspect that there's one available for CISCO so I specify which tunnel name and so on since I designed different tunnels with different access levels. So if we deployed to the entire company will not meet company’s min. standard security to segregate or have different access level per tunnel.
I know that CISCO doesn’t have client as of yet for WM.

You can have different access levels with the built-in VPN client, its all in the configuration of the back end though with your access servers and the authentication servers (Radius/Tacacs). Using a proprietary client seems to defeat the object of open standards doesn't it? Plus it's something else to support (and go wrong..)
My 2cents..

I am using SSL VPN .
Easy way to acess:
- WEBMAIL
- FileShare.
I am using the ASA 8.x version , wich presents a ver nice web page for mobile devices.
SSL VPN
I have a ASA55xx ver. 8.xx as well I like that, I think I should enable it and will do the trick without CISCO VPN Client
SSL VPN
I have enabaled SSL VPN on my ASA55xx and is working like sharm , I like it.
Thank you eveyone.
They provide that now.

Work URL Exceptions

Has anyone figured out how to get the Work URL Exceptions to work? I have both my private IP Addresses (192.168.0.*) and my domain (*.mydomain.com/*) listed. I am using PPTP VPN, but it only works for Exchange ActiveSync. I am trying to get it to start the VPN Connection for other program such as RDP, or Internet Explorer with no luck. I even tried to RDP into the VPN server, but was not successful either.

[APP Idea] server app

Ok, the basic Idea of this App is to provide an easy setup for an ftp & or web server (should be customizable) which also provides a shortened url for easy access.
also my idea was that the app can do this over different of protocolls, bluetooth, w-lan usw.
is something like this technically possible?, i know there are ftpserver apps out there but it is not quite the same.

Easy ftp and web server apps already exist that work over wifi. bluetooth is tricky, as a normal web or ftp server won't be easily usable (but bluetooth already has methods of doing file transfers that works quite well, and there are apps to handle this, like Blutooth File Manager). What is USW?
AFAIK, there is not an app to do those things over ad-hoc wifi - they all require connecting to an access point. Being able to open up an app and have it set up an ad-hoc wireless network with another android device and allow easy high-speed file sharing would be awesome.
As for cellular data, there's a major hurdle to overcome on some carriers. Verizon, for example, does not allow incoming connections over cellular data. So you can set up a web or ftp server, but you won't be able to access it. The way around that is to have the phone establish the connection to some server, then have that server act as the gateway. Bandwidth is not free, though, so I suspect you'd be hard-pressed to find an app that includes that feature, unless it also requires that you set up your own server gateway. I'd like to see something like this - an app that establishes general-purpose 2-way comms with a server application on command (by hitting a "start" button in the app), which then allows you to set up different types of servers (ssh, ftp, web, etc) that are routed through that gateway machine that you set up.
One way to accomplish that whole scheme is to use a VPN - when a VPN is established (even over 3G), you can access any server you want to via the VPN-assigned IP address.

What is the difference between VPN and VNC?

VPN stands for Virtual non-public Network, and it is a means that of firmly connecting individual users at remote locations (at home, or whereas traveling) with resources on field over public communication lines which may otherwise not be secure. VNC, or Virtual Network Computing, permits you to attach to associated management an pc from an overseas association. for instance, you'll use VNC from your computer to remotely management a PC on field.

Ipv4 range

Hello, I'm fairly new to programming let alone development, how ever I need to connect my home computer and mobile device to a class server provided by my college. The server allows user access by username and password but as an extra layer of security the instructor limits access to set ipv4 addresses. Given at&t as my provider I've been using mobile hotspot as my main internet service, unfortunately the ip address changes frequently through this service. I was wondering if there was any way to capture the range of these ip adresses or if anyone could direct me on another way to create a static address through which I could connnect (perhaps a very basic web server?).

They need to change their policy. No consumer internet service uses a static IP, so even though yours may change faster, everyone else in the class will eventually have the same issue. They need to invest in a VPN if they want network security.

If this is an absolute requirement one option could be to get a static IP address from AT&T. I know Sprint offers that as an option for around $5 a month. might be a way to do this. The only other option I can think of is to get a server on something like cloud at cost or digital ocean and use it as a proxy.
Does your school offer up a VPN for students? One thing you might be able to ask the professor is if they will allow you to use it from on campus.
