apexdc++ comodo problems

Great job on comod firewall i tested a lot of free software and comodo is great.
Installed ok , registered ok works great on every aspect but i have one big problem.

I have a PPPoE connection for the internet and ip using dhcp for local network.
He have a dc++ hub and it alows acces only if i have ip from dhcp (is always the same).
After i installed comodo i can’t get anything from the hub.
I connect ok, i can chat but no file transfer even to get the list of files.
I tried even setting the security settings to allow all but no luck.
Any idea what can i do ? I like comodo but if i can’t use my network correctly i will go back to outpost free edition.

thanks in advance for any response

ps: sorry for my bad english
