We've got a new Thinkpad here, running Windows 7. Having problems with the networking/Access Manager. When using the wireless profile, everything works fine. However, when using the wired profile, we're unable to use web browsers. Everything else works fine, we're able to connect fine with anything that doesn't use port 80 or 443 (for example, DNS, traceroute, ping, SMB, and even surfing to websites on port 81 works!).
Machine was originally setup with the Windows built-in utility rather than Access Manager. Have tried resetting everything, but still have the same results.
Any ideas (other than reformat and start fresh)?
Update: Port 80 and 443 work fine over IPv6, this appears to be an IPv4 specific problem.
