iptables under linux-emulation (debian?), can it be done?

[l0kit0 at exactas.org]

hi,
im trying to get some use of the linux emulation :), ive got a debian box
just for iptables tryouts (thats a waste of a machine:). i guess the best
choice is to get it to work in my fbsd5 and play there, but,
linux_base-debian y marked a broken some time now, should i expect it
working soon?, i guess not for 5-stable :/
i prefer not to use redhat base, but if you say it is the only way, i
would :(, now, can i play well with iptables on linux emulation? (it will
be too complicated?).

thanks in advance

ps: maybe not the right list, but related to the mail topic: shouldnt be
more practical to have /usr/ports/<categories>/linux-<app> under
/usr/ports/linux/<categories>/<app> (i have it shadowed right now, and i
found it more practical, what do you think?).
(sorry for the bad english)
