Re: [suse-linux-uk-schools] Firewall advice needed.

The structure goes something like this. External if is connected to our school network, on a 10.4. address.

Is this correct or just a typo? addresses starting 10. can't be external - unless they are just another local network. As TA says, a simple pic (I prefer jpeg as I can never format ASCII ones:-) of the topology really does help. Adrian
