    So, anyone know of a utility that will do this? Say you're in a courtroom, or in another office, or anywhere with a firewall, and they don't let all traffic out... just port 80? You need to be able to VPN in to work, access AIM, etc.

    I guess you COULD route your port 80 shit on a certain address to your VPN server, but... short of that, is there anything that will detect if you are behind a restrictive firewall, and then bring up a VPN if you are?

    I'm not a windows programmer... how would I go about creating this?

    how will you be able to VPN out, if the only traffic they allow is on port 80?

    EDIT: It would be cheaper, and a better solution just to buy a verizon card, and have them use that connection.

    Not an option, not quick enough.

    They allow traffic OUT to port 80... so I open a tunnel to my server, which recieves on that port. Traffic can go out from there.

    That would be nice to have. Tampa airport has free wireless but it doesn't work with our VPN because it blocks incoming UDP port 500. :(

    You could always have something set up where port 80 gets redirected to the VPN port of your internal VPN server... but a utility would be more better.

    Actually, can you change what port XP Pro's VPN client uses?

    Not quick enough? They have cards as fast as a partial T1.

    what type of VPN? if it's PPTP, then you might be out of luck. I'm guessing people who filter on port 80 allow tcp/udp, not GRE.

    No shit? Well, anyway it would be nice to be able to get access from behind firewalls.

    IPSec then?

    Wow, they didn't have Verizon 6 months ago... or at least I hadn't heard of it.

    How much is it?

    the 80/mo is for unlimited access. the quick 2 net, (whatever the hell that is) is extra

    I get the feeling 'quick 2 net' is their ISP. I can't find out though... that shit is confusing.

    You actually used this before?

    i use one for work and my accountant just writes them a check for 80/mo + tax. I think that service is if you have an analog or non-broadband signal. I have never been charged anything for it.

    Verizon EVDO BroadbandAccess for the win.

    BTW, I don't think there are any VPN's that work on a single port.

    That looks like the way to go... I wonder if there is a break for 4-5 users...

    You would route all data through a tunnel to port 80... ssh would work.

    You won't get a VPN to tunnel through SSH. Trust me, I spent the last couple weeks on it.

    too slow? well, you would have to tunnel every single port the vpn might end up using for it's connection
