Hi Everybody ,
I'm newly using ipfw ... I have some quesitions about ipfw configuration
..
I'm maked changes on defult configuration in rc.firewall for simple type
but I don't understand something ...
# Allow TCP through if setup succeeded
${fwcmd} add pass tcp from any to any established
# Allow setup of incoming email
${fwcmd} add pass tcp from any to ${ip} 25 setup
I checked man page of ipfw ; setup matches packets have SYN bit or not
....
Upper rule is accepting setuped connections that ok ( please correct if
I wrong )
Question is Why I need to set setup options on secound rule ...
I mean I must to open 25 ( smtp port ) to all What is the setup option
role ...
