URGENT!! How to block SMTP port from public address?

Wed Aug 09, 2006 6:43 pm

Hi, this is my problem... I'm using a MT 2.9.27 router for share ADSL connection with 5 pc (intranet). Someone use my public IP like a SMTP server for spamming action. How I can stop this? I think I need to block traffic on port 25 on public ethernet card, but how I can make this?

Thank You

Paolo
