Creating A Linux Firewall using webmin Rumi, January 12, 2009January 12, 2009 Here is what I need to do- I want to block ping on eth0- my external link I want to open everything else on eth1- internal link Let’s assume eth0- has public IP and eth1 has private IP I want to allow SSH, auth, httpd and certain protocols to eth0. Other than these- all communications are blocked by internet traffic. The screenshot below gives a perfect look- So, using webmin- it’s quite easy and simple! Click Networking > Linux Firewall If there’s any existing firewall rule present- click “Rest Firewall” Select “Block all except SSH, IDENT, ping and high ports on interface:”- choose the public interface which is eth0 in my case Then click setup firewall. Your firewall is ready. Below few screenshots will tell how each window looks like 🙂 Administrations Configurations (Linux)
