Thanks heaps for your responses. It is an SME6b3 server (not private, I might try that instead.) The handysoft data doesn't reside on the SME server, as the data was corrupting weekly, and were advised by handysoft to NOT use linux and instead use Win2k Server. So, there is a Win2k dataserver, and the SME firewall. I left it in server / gateway mode, as eventually they want to have their own website, and e-mails.
Anyway, shall let you know of the outcome.
