Hi Everyone, Lately I have fixed a problem with ADSL and internal network that had the nature of being non consistant (e.g. coming and going). It apears that sometimes the ISP does more than one tunnel ( to switch the connection from one server to another?). This reduces the MTU and makes the internal network into a black hole. In the case I dealt with (pure M$ environment) the solution was to reduce the MTU on the internal pc's to 1400 . With a linux router you can do it easier - just reduce the ppp MTU to 1400 and add a rule in your iptables to adjust the MSS to the ppp interface. This might be here also (though the symtoms are a bit different). Dani
