Try reducing the interface MTU further. It's possible that there's a misconfigured router between you and the sites *and* a part of the route has an mtu of less than 1492. ``set mtu 1480'' or ``set mtu 1460'' may work. > I have been having problems with the the newer Windows machines, 2000 & > Me, not being able to access some websites.
