This is weird! I noticed that I was having trouble accessing *some* websites (www.altavista.telia.com, AltaVista's Euro-Mirror). The problem did not occur with *most* websites (maybe this rules out Apache as the problem cause). Note that the problem also occured on Win95 PC's that are connected to the Net via the Linux box (via a CSlip link to a Linux box, MTU 300). It wasn't Netscape's problem, because lynx (on Linux) showed the same symptoms (lynx on the Linux box other side of the CSlip link was fine, tho). I changed my MTU to 1500 and my problems disappeared. So, thanks for the tip! Weird tho.... Regards, Peter van der Landen
