Firewall

In order to make full use of my half-duplex WiMAX link, I started looking for anything and everything I could use to optimize it. Linux has some pretty decent utilities with iproute2 and netem to handle these type of configurations. They don’t compare to OpenBSD’s PF, but they work once you get the setup in place. Due in part to how ugly TC is out of the box, I really like FireQOS for defining the basic configuration. The developer also makes a great iptables wrapper called FireHOL, but iptables rules are easy enough to write in my opinion. ...

First you need to open the iptables firewall settings: ## NetBackup Client Firewall Ports iptables -D RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited iptables -A RH-Firewall-1-INPUT -m state –state NEW -p tcp –dport bpcd-j ACCEPT –src iptables -A RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited /etc/init.d/iptables restart

The most beautiful firewall I have ever come into contact with is Sidewinder. The first day I learned about Blurbs in the military was the day I began to jump with joy inside. Sidewinder has a very unique product that allows for an ultra-secure configuration. As with all things, McAfee will screw them up. I am sad inside now. McAfee buys Secure Computing
