Cannot connect with my router...

I thought i'd post this here since the players usually have better solutions. Maybe someone might be able to solve my problem :(

Cannot connect to AC with my router, you know the drill. It is able to connect from a direct connection from the DSL modem, in my living situation I cannot directly connect to the modem. I can only connect via a router:

I have a Linksys WRT54G
Before that I had a Netgear wgr614 (because some said netgears wouldn't connect to AC)

Yes I have NAT DSL
Yes I have port forwarded 9000-9013
Yes I made static IP
Yes my firewall is allowing the client
I even bought another router...

My subscription ends in 4 days and I haven't even played the game once.

I am open to anything new, i've read all your guides...
