    I want to use my TP in wireless areas like libraries and internet cafes. I want to ensure some level of security to avoid being hacked. On my laptop I use hotspot shield (which is free.) I'd like to use something on my TP that is free and easy to setup. Another thread had some complex intructions for setting up a VPN connection to your home that needed a dd-wrt home router and for your home computer to be on at all times. (These instructions were well over my head.)

    I think you're asking the wrong question. Sounds like what you want is a firewall, not a VPN - unless you are accessing files on a private network through the internet. Even then, something like SSH might be a much simpler solution. I'm guessing that if you can get yourself into a terminal you should be able to set up firewall rules on your TP with iptables - but I haven't tried yet so I can't be sure.

    The TP already has a firewall running and it blocks all incoming ports. The outgoing ports are open, but unless you have a trojan virus on your TP that's not really much of a problem and I can't imagine linux trojans are that common in the wild.

    I don't think trojans and other direct incursions are what the OP is concerned about. The biggest risk of using public wifi is session hijacking and packet capturing. Using a vpn encrypts all of the traffic going over the wifi back to your home network where it is safe(r). For some applications, like splashtop, VPN could be very useful, as splashtop is sending the data in the clear, so any packet sniffer could eavesdrop or potentially hijack the session.

    Best advice for public wifi is to be smart about what you do while you're on it, and to use https connections as much as possible. Most current SSL/TLS implementations are kind of weak, but they're a lot better than nothing.

    I'm looking into VPN as well. If I find a good solution, I'll post it.

    Get an account with an https based web anonymizer service and use this when you are browsing. Non-browser apps will still be at risk if they don't support https logins.

    sorry - I know that's not free and that's not what you want to hear. There may be some free options like this - but I wouldn't trust them unless I was running them on my own equipment and knew they were open source and had been vetted by others for a while.

    I upgraded my router to a Cisco rv042 specifically for VPN. Works great with pptp VPN on the TP. Now if I could just get pptp VPN on my Pre3, I'd be happy camper.

    You are correct. I was concerned about people in wifi areas like cafes and libraries running packet capture software. The VPN software will encrypt all my communications, so even if someone was sniffing for packets, they would only pickup the encrypted packets which are useless to them. As I mentioned earlier, I run hotspot shield on my laptop and I "feel" more secure knowing it's encrypting my wifi data. What we need is a simple and free VPN encryption to keep our data secure when we are out in public.

    Well, you can get a router with VPN capabilities for your home. You can get a pretty good one for $100-200.

    I have a dd-wrt router. But I don't know how to set up an encrypted VPN session when I'm at a public wifi spot. Do I need to keep my computer on ?

    IMO you are a little too paranoid, if you are connected via VPN, you should be relatively secure depending on the set up. If your concern is higher, do not use the Touchpad until you are absolutely sure your communications are highly secured.

    I don't have a dd-wrt router, but I did a little research. Dd-wrt can support either pptp or openvpn (SSL) VPN. The TP can do IPSec or pptp (you need to download the HP pptp VPN app/patch from the catalog). So basically, you'll need to have a version of dd-wrt with pptp support installed on your router.

    Read the dd-wrt Wiki on how to setup pptp. Also try searching for threads here about how to use the TP with dd-wrt.

    However, if you're really paranoid, pptp is not considered that secure anymore.

    For me I use pptp cause the TP's version if IPSec doesn't seem to like my router's version of IPSec and I'm not really a high valued target
