redirect of newsgroups

For those of us sitting behind a firewall that blocks out all of the alt, rec, etc.. newsgroups...is there another way to access these groups? For example, redirecting the contents of alt.2600 to, say, comp.2600 (because this firewall allows the comp.xxx groups through). Or any other hacks around this inconvenience? -----BEGIN PBP SIGNATURE----- Version: 1.0.0, Copyright 1995, Pretty Bad Privacy David Klur dklur@dttus.com I am who I am because I say so.
