Though there's no explicit support (as far as I can tell) for firewalls in ange-ftp mode, through a little trickery it's possible to make it work through a particular kind of proxy.

If the proxy in question asks you to give your login name as , you can trick ange-ftp into sending this as your username.

Note that simply opening / won't work, probably because ange-ftp interprets this as a login of realuser at the unresolvable hostname Probably the code could be changed (bugfixed?) to interpret this in the more useful way; I don't know enough Emacs Lisp yet to do it.

Here's the workaround. First load ange-ftp (Most easily done by trying to open a /user@host:file style path and then cancelling), then do M-x ange-ftp-set-user RET. For host, enter the address of your proxy. Enter for the user. Now you can open files at that host like so:

C-x C-f /@proxy.address:file

The only drawback (besides the annoying setup each time) is that you can only have an ange-ftp session open like this to one host at a time (since it associates the username with the proxy's address, not the real remote host's).
