I set up a Linux machine last Feb as a webserver, the idea being to use it this year as a teaching aid or a means to publish pupils work. It worked fine within and without our network. I could access it from home. We had then an ISDN line and a simple router. I switched the machine off until last week. Now I can see the machine within the network, but not from without. From this linux machine I can ping anywhere within our network, including the router, but no further into the outside world. The only change is that we have installed a new leased line and new router. Would the problem possibly be with this or I have I inadvertantly made some change which is causing this problem? Any ideas? Chris Chris Davies Head of IT Epsom College College Road Epsom Surrey KT17 4JQ tel.: 01372 821178 fax.: 01372 821005
