Hi !
In my progress of still learning firewall with ipfw, I have a question.
Can I convert the following rule:
${fwcmd} add pass tcp from any to ${oip} 25 setup
into on of those (which one would be the best, I guess the second one, right
?):
${fwcmd} add pass tcp from any to any via tun0 25 setup
${fwcmd} add pass tcp from any to me in via tun0 setup
I ask this question because I do not have a fixed @ip on the outside interface
so I cannot use the ${oip} (outside @ip) variable.
By the way, is there a difference between:
${fwcmd} add pass... and ${fwcmd} add allow... ?
Thanks in advance for your answers.
Antoine
