Let me make myself more clear. I m a local ISP providing Internet Connection using CAT5 termination, direct to the PC. Hence,
1. When my firewall blocks some1 automatically from accessing the net, though the user might not be deliberately create trouble. How do i re-allow him access to the net (of course, in absense of my administrator when he is not reachable)? I m using IPTABLES for natting. 2. Mail Server which we have setup is Sendmail. When I try sending mails using Outlook Express, thru my SMTP mail server I get an error, but when I divert the same mail thru my ISPs SMTP server, it just goes without any error. The settings used are the same, except the SMTP server Protocols are changed in the Outlook Express. Hence, If you can pls help me sort out this prob.
