Net :: rcfirewall.dsl

I've installed the above. In its non-.dsl form, it's a bash script which (even) I could edit.

I don't understand the process of creating .dsl files, but, as far as I know, I can't edit such a file in a text editor.

I've now installed amsn-0.94.uci. As best as I can understand it, I have to open port 1863 for amsn to work properly.

Is there some way in which I can do that, assuming I'm right that I can't edit rcfirewall.dsl in a text editor?
