dcgui-qt active with fw

[gizmo.tar.bz23]

hi guys. i have a little problem
with my dcgui and maybe someone
could help me.

i've got a little network with a
router and four boxes behind. on
the router i'm running gentoo
with an iptables firewall from
sourceforge [jays firewall] i used
the script to make my firewall and
did portforwarding from the router
to the other boxes. the connection
i use is dsl with 2 network-cards
and an isp that uses a dynamically
assigned ip. it works all fine
but if i'm going to switch dcgui
to active mode i can't start any
download and i get no search results.
in dcgui-options i marked wrong/ip
and in the hostname/forwarder
box i put the ip from my isp's dns.
anyone has an idea??? did i something
wrong with the hostname/forwarder
option in dc???? iptables -L tells
me that ports are forwarded corectly.
