    I have a MacBook Pro that, from inside XP, can ping outside servers (google, yahoo, my personal server, etc). However whenever I type in a address in IE, I cant get to the webpage. Likewise, if I go to the command window and telnet www.google.com 80 it will never respond.

    I'm confused that I'm able to ping from the guest OS, but I cant do anything else network related. You figure if I can do one network thing I should be able to do it all.

    I have tried some of the steps listed in the FAQ regarding checking network settings on both the Mac and PC side.

    The only caveat I can think of is that I'm connected to the internet with a Sierra Wireless 881 HSDPA USB adapter (so my Mac has a PPP connection). But still, if OSX works fine in all respects (ping, web, mail, etc)...

    Parallels Jan 08 update
    OSX Leopard
    XP SP2

    I should note that this doesn't work when the connection is a PPP connection, but works fine when its hooked up via ethernet.

    OK, I was sorta able to get it working, but its far from an acceptable solution...

    1. Make sure Parallels NAT is on and operational.
    2. Share internet connection from PPP adapter to en3/4 (whichever one is the NAT)
    3. Internet will now work inside the VM.

    However the problem is that when the Mac is rebooted, the Parallels NAT will fail because of the internet connection (the parallels NAT pulls an autoconfiguration address).

    I'm going to uninstall and reinstall parallels this morning.

    After losing my typed up post I had before, I'll keep this brief...

    I'm still having the problem where parallels wont communicate over the PPP connection.

    The only odd thing I noticed was when I was sending large ping packets from XP, anything larger than -l 1472 wouldn't make it. The PPP MTU is set at 1450 and not 1500

    ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1450
    inet 166.129.229.178 --> 10.64.64.64 netmask 0xffff0000

    Any ideas?

    OK now I'm finally getting somewhere...

    tail -f /var/log/system.log

    kernel[0]: FW-1: fwosx_should_filter: PPP_IP with unknown frame 00 21 ffffffc5 00 00 ffffff8e fffffff3 56

    and there are a ton of those messages every time I try and go open up a webpage inside XP. I dont get those messages when I'm just trying to ping or resolve a DNS name. The part in italics will change with each line, but the message is the same. I've checked google and nothing came up when I searched for that line.

    Fixed

    I was able to fix,
    refer to this link: http://kb.parallels.com/en/4885
    make sure you have activated internet sharing of ppp adapter for the parallels NAT adapter.
    step 3 of the article.
    good luck

    Hello,

    I have exactly the same troubles with my virtual WinXP installation. The network is configured in "shared networking mode". At home my MacBook is connected by WLAN and everything is fine. My virtual WinXP installation can connect to the internet. But when I´m on the way my MacBook connects to the internet with a USB UMTS device. Now the virtual WinXP installation gets a timeout when browsing the internet (but ICMP ping is possible).

    Can someone tell me why network access through the WLAN network device is possible but the UMTS device not?

    Parallels is up to date.

    br, Gregor.

    Probably drivers

    I thought to have fixed the problem, but i am still into this issue.
    Also i have a windows laptop and is disconnecting as mac is doing random.
    I think the root cause of this problem is the provider or the device drivers.

    Hi,

    thanks for your information.

    Bur could you please explain how to configure the OS X Parallels network adapters and the network configuration in the virtual machine (in my case it´s Windows XP)?

    Thanks in advance.

    br, Gregor.
