I enabled the provided modem DMZ to IP 192.168.0.250, also rebooted it, should I try to connect?

should this solve the Q3 arena problem too? or is it another problem?

no
But what the hell doesn 't joke about test

I just tested this, it works for Alien front online, so it should work for the other games that need DMZ, thanks a lot to everyone that helped me get online! specially to megavolt85.

I hope this post could help in the future someone that was as naive as I was about this all configuration thing.
