DDNS and port forward in dual router setup

[maddy_in65]

I have BSNL BB configured on Dlink DSL2520U modem router and Asus RT N13U connected to it. I am trying to figure out DDNS configuration but failed to configure it. I have noip account and i tried to configure it on Asus RT N 13U but unable to do it as i dont know to how to port forward for DDNS.
I also not able to setup printer on Asus RT N13 router. I followed RT N13 wiki but it didnt work. Please can some help me to sort these issues.
BTW Asus RTN13 is working DD-WRT firmare.

I have DDNS setup and its working fine on DDWRT. Please post exact issue where you are stuck.

Currently DD-WRT router is behind ADSL modem (Dlink DSL2520U), it gets local IP from modem and I am not able to configure port forward on modem. If i enable DMZ on modem, does it forward public IP to DD-WRT router.

I would suggest put your adsl router into bridge mode and let the dd-wrt router do the authentication.
DMZ won't forward the public IP. Do the setup as above and configure all services. It should work.

Thanks a lot for help, configured Asus RT-N13 for authentication and DDNS shows it is successful. HP leserjet printer is attached to router via USB. I am able to access printer via PC in the same lan but how can i access printer using DDNS host name.

I haven't personally tested such scenario like printing from remote location. But i think you need to forward the printer port.
