The FreeBSD box acts as a gateway to my ADSL connection. I'm using the simple firewall as defined in rc.firewall. However, some of the default rules are preventing some services from working. But I don't understand why. Below are the rules and a description of what they prevent when they are enabled. If someone could explain why the rule stops what it does, I would appreciate it. oif=ed0 # if either of the following two lines are enabled, it stops my Pegasus # email client from accessing the POP server at my ISP add deny all from 192.168.0.0:255.255.0.0 to any via ${oif} add pass tcp from any to any setup -- Dan Langille DVL Software Limited http://www.dvl-software.com/freebsd : my [mis]adventures To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
