@george1421 Thanks very much for the information. I’ve set up the A records on both DNS servers and everything seems to be working okay in that I can ping ‘fogserver’ from both networks.
I started capturing an image from the Student network but got an error that seems to suggest that a password is wrong somewhere (ftp_login():Login incorrect) so I need to fault find this one. I’ve found a fair bit of info on it so I just need to find the time to sort it out.
Thanks again to every one for the help, it’s much appreciated. I’ll report back once I have a chance to get back to it.
