Can someone clarify whether I've made a mistake or mis understood the tutorial? I'm using the latest iptables (1.2.8 I believe) on a Linux 2.4.22 machine.
In the tutorial, it says -p tcp,udp is permitted; but the manpage states nothing of the sort(but implies that it can't be done that way).
In the past, I've been using two lines for both tcp and udp settings. I just decided to re-read on the tutorial and noticed that I could use the tcp,udp (or udp,tcp) way. Saves space.
But it doesn't work. I googled and came up with an archived message stating that there is indeed an error, but that was two years ago.
If it is indeed true that I can't specify protocols like that, is there a patch that can allow me to do this?
Thanks for the clarification.
