I realise that this won't be immediately helpful, but: How to re-enable their access is going to depend on how it was disabled. You might want to do "iptables -l" on the INPUT, OUTPUT, and FORWARD chains to see what rules are in effect. Essentially, you're not giving us the information necessary to solve the problem, undoubtedly because you don't know. Perhaps you had best consult the "professionals" who set up your Linux-based router, and get proper documentation from them for their work. > 2. Mail Server which we have setup is Sendmail.

Again, nowhere near enough information to diagnose the problem. Is your SMTP server working at all? Is it processing local-to-that-host mail, only? Some distributions, such as Red Hat, have lately made their SMTP servers default to processing only host-local mail, unless and until you configure them otherwise. -- Cheers, "By reading this sentence, you agree to be bound by the Rick Moen terms of the Internet Protocol, version 4, or, at your [EMAIL PROTECTED] option, any later version." -- Seth David Schoen _ Philippine Linux Users Group.
