Connecting 2 PPC Ad-hoc - Networking

HI!
I need connect two PPCs with wifi... VPN..? How I make it?

they would need to both connect to a vpn server.
but then the question is what do you expect the devices to do with each other. neither have any server type services for the other to connect to.

it would require one or both of the pocketpc's to run a VPN server if there is such a server program for pocketpc's at all

sounds like a non starter to me.
i think a vpn server needs to dish out IP addresses.
thats just to start with.
unless you are connecting both ppc's to a vpn server

Please elaborate. Do you mean direct P2P connection (which is very easy to do - see my related articles on this), or a plain Internet / VPN-based one?

In internet-less P2P connections, you don't need VPN either for assigned IP addresses.

Wifi access to internet via ISA firewall

I've just set up a small wireless network at home through which I intend to use several devices to connect to the internet through my LAN!
The LAN gateway is running ISA 2004 and my home computer is running the necessary Firewall client (a completely secure connection with username and password)!
Now everything's working fine... the pocket pc hooks up just right and i can browse the network and do what I could probably do using my own personal computer BUT the internet doesn't work!
It keeps asking me for a username and password (which like i usually provide in internet explorer on my personal computer) which i do supply... three times in a row after which it gives me an error saying that ISA cannot authenticate me!
The home computer doesn;t run the internet without the firewall client, and i'm supposing the pocket pc is facing the same dilemma! is there any way to circumvent this issue? perhaps a mobile version of the isa firewall client?
Please help. Thanks!
afaik there isn't a mobile version of the firewall client.
I set my ISA server to allow anonymous internet access ,and set all my machines up as secure nat clients (set isa servers ip as default gateway, I use a dhcp scope to do this). There is lots of info on this on microsofts ISA server website, I'd suggest a look there first, or try a google for secure nat.
Good luck, works well for me but ymmv.

GPRS and Static IP with VPN

HI guys,
Does anyone know how to get a static IP address when using the GPRS connection to the internet. The reason being is because our corporate firewall has to recognise the device through it's IP. Is there any other possible methods for recognising the user?
Also does a VPN work well over GPRS and is there any extra configuration involved on the VPN server
Cheers
Any answers would be great.
Unfortunately there is no simple answer to your question. AFAIK you cant get a fixed ip on gprs, but if your using the right firewall and the right vpn host you dont need to.
I use and supply windows sbs 2003 servers and vpn into them regularly. I have also used citrix to achieve similar results. Might be a bit difficult to persuade your firms it dept to set up something like that for 1 person though.
PM me if youd like any advice.

Hello Billy,
You ask a good question, but the answer isn't simple. Most carriers do have two types of APN (Access Point Name) provision for your SIM: "private" APN (which provides a non-routable IP assignment from behind a NAT, for basic browsing and e-mail functionality) and "public" APN (that provides a routable IP assignment, which is the Minimum Requirement for a more sophisticated connection type, such as VPN, etc). However, both of them are assigned by a DHCP (Dynamic Host Configuration Protocol) Server on a GGSN (Gateway GPRS Support Node) of your particular GPRS network operator. In either case, the end result will obviously be a DYNAMIC IP address on your GPRS terminal (be it a laptop PC, a PDA, or phone)
Some carriers do offer what is called a "dedicated APN" provision, which gives the subscriber their own IP range to choose from (almost like a small subnet), but it is only available to corporate giants like Pepsi (for example).
Now, to sum it up, you must have the proper APN provisioned on your Mobile SIM account (which the provider will normally call something like a "VPN data package" in billing terms). Then, you must obviously establish a GPRS session before you can connect your VPN client (but remember that most basic VPN clients work the best). It is pretty sad to say, but Microsoft Windows-embedded VPN client on Win2k/XP Pro so far has performed the best with no quirks whatsoever. It has to be via PPTP...L2TP has also worked for me..otherwise, the fancier (and more secure) the VPN tunneling protocol, the more its likely to fail. Normally all you need for a basic MS WIndows VPN client config is the Server name (or IP address), the user name, and the password.
Hope this helps,
Let me know how it goes,
Alex

VPN and TS Its like pulling teeth
hi all this has got to be the most anoying problem ever. i can connect to O2 vpn access point and hence i can connect to my work vpn server. however as soon as i try to open a TS connection to my desktop (through the vpn) the VPN connection is dropped and i never connect. Can anybody tell me why? if i have a vpn connection to my work server why does TS try to make another connection and bomb out the original. Is there a fix or another way of doing this i.e. does a external IP have to be nat'd to my desktop IP on port 3389? all help greatly appreciated. Ian

OpenVPN (WM6) connects but anyhow doesn't work...

Hi,
I have a HP Ipaq 210 series PDA with WM6 and trying to get OpenVPN to work for allowing me to connect the our university network.
After presenting my user data, OpenVPN says "connected" and displays the green symbol. Nevertheless my browsers (PIE, Opera Mobile) or any other internet app is able to "go outside".
Do I have to tell Windows or the browser to use the VPN-tunnel anyhow? I just don't know how to proceed.
Any information that could help me?
Kind regards,
roke
Can somebody please at least indicate how the configuration in the windows connection manager should be? ISP/work and so on? network device should connect to work/ISP? Configuration of OpenVPN: Use connection manager? On which network? Exclusive? ...
I just don't know what else I can do. The admins responsible for the VPN are bloody amateurs and don't know anything about windows mobile...
Help me please...
Regards,
roke
I have not tried openvpn on the ppc, but i run some openvpn connections for my company.
The openvpn server is configured to push the various parameters to the client, essentially that is the ip address ranges which should pass through the vpn and any DNS servers. (Excepted for bridged mode, where the ipaddress will be in the same subnet as the main site.)
From the Openvpn web site :"By default, when an OpenVPN client is active, only network traffic to and from the OpenVPN server site will pass over the VPN. General web browsing, for example, will be accomplished with direct connections that bypass the VPN." Why would you want it any other way?
What is it that is not working?
Can you access the sites and resources with the openvpn connection?
Can you access the sites on the openvpn server side by ipaddress?
Regards

If you're connecting from the outside of your network then you need to make sure of the following:
1. FTP is set up on your router to be forwarded to your IIS server
2. FTP site set to allow either all IP addresses to connect, or at least the external IP address you're coming in from (use www.whatsmyip.org to check your IP)
If you're connecting from within your network, you need to create a forward lookup zone in DNS for dyndns.org and add an A record of bccan with your server's internal IP address.

Also just to add, I would not worry as much about a software firewall on your IIS server , you will cause more problems than you will fix, as stated above if you only open the ftp port on your router to the outside, then no other connections will be able to get in ... Hardware firewalls/routers are a much better choice ..
As far as antivirus goes, it depends on how much money you want to spend, for free I would go with the ClamAV recommendation it works very well in a server environment.
Symantec which is not free really works well too ...
EDIT:
IMHO I would not use the machine name as your external DNS name, if that is what you are doing. That way you can use the machine name when connecting locally on your network and the DNS name when external ... It has just been my experience that using the same name for both machine and external DNS can cause all kinds of problems for other services you may want to run on that machine in the future ..

[Q] [REQ] OpenVpn full solution for SGS2

Hi all,
I have been tinkering with connectivity into my corporate network and so far been able to get a connection to our Office Communicator server via ASProxy and a secure wireless connection. However I am looking for a solution that works across my 3G connection via a VPN.
I have looked at the market place versions of OpenVpn and I cannot get it to work with our Cisco Gateway. I got stuck at the tun and adb part, so not sure what I need to do at this point so though I would ask the experts on here ;-) There has been much work on a very important missing part which was a user authentication proxy, so the next bit for me would be a means of connecting to an IPSec/UDP Cisco VPN Gateway that works with my Domain username and then a fob generated password.
Any help from you guys would be most appreciated and perhaps I can share my ASProxy configuration for anyone wishing to get their's working....
Thanks
Avalon
Hi,
you can't use an OpenVPN client to connect to a Cisco (IPsec) VPN server.
If you want to connect to an OpenVPN server then you can use OpenVPN Installer and OpenVPN Settings from the market.
If you want to connect to an IPsec server then use the built-in android VPN client or even some proprietary Cisco client from the market... (don't know about these as I only use OpenVPN)
Hi, thanks for the reply, however the built in VPN client will not work with our server. There is a Cisco anyconnect client that does connect, but we need a license for it which we dont currently have.
I will keep trying....
