Topic: Internet connection dropping out.

[os1ae]

I am having some trouble accessing the internet through SME.  I have an ADSL connection going through a router into a PC running version 6.0.1-01 of SME Server, then out to a switch that has a couple of PCs running Linux/Windows attached to it.  When accessing the WWW through these PCs I can get onto the internet, but after about 5 mins. or so the connection is broken.  If I then log onto the server and use Lynx to get onto the internet it works and then the access from the other PCs is OK too for about 5 minutes and then the same thing happens again.  I have no problems accessing the internet directly, only when going through SME.

I'm sure it is just a timeout setting that I can't find, but any help would be appreciated.
