    Can't find webpage- TCP routing?

    I sync with my calendar and laptop at work.

    When I cam connected, I notice I cannot get to some webpages- coincidentally, pages blocked at work (no, not porn sites.)

    Does the XV6600 route through the laptop instead of its own internet access if commected and if so, how do I change that?

    My guess is that it is connecting through a VPN, and quite often, they are configured such that all traffic must go through the VPN. This is a security issue at times. If someone is VPNed into your office, they could also potentially be infected/running an agent, you would prefer not to have them be able to directly relay this information in/out.

    I'm not sure I follow, Mark. I am in office, on the LAN, and the XV6600, of course, has EVDO. I noticed this as well at my previous employer's.

    Well, basically, when you set up to wirelessly be able to connect to your laptop/pc, you generally have to connect via a VPN. So, once you have set up this VPN, it dials it whenever you synch. While this VPN is active, it is very common that ALL traffic is routed through this "virtual" interface.

    This means that if you visit a web page (even on a PC) that has the VPN be its default gateway, the data will pass through your modem, to your work, where it will then go to the router there, and out to the world. On the way back, it goes to work, then through your VPN back through to you.

    Therefore, any firewall/blocked sites will be blocked while you are on your VPN. It sounds like the XV6600 must be routing all TCP/IP traffic through the VPN by default. Typically, Windows also has this as the default behavior. I adjust that by using Microsoft's connection manager installs, and setting up routing manually.

    I really need to check for typos when I post. "commected"??? Sheesh...

    I am using USB, not wireless connections. The wireless is from using EVDO, which has nothing to do with corporate VPNs.

    You can tell your phone what to do under the advanced network settings. I think the default is that when you're connected to a PC, you use that machine as a gateway. That means you're subject to the same restrictions vis-a-vis web access as that device.

    If you poke around in the advanced settings you should be able to force your XV6600 to use the EVDO network for internet access instead of using your PC's network access.

    Yeah, what EnnuiEnthusiast said.
