Having trouble with port forwarding for DDNS

[smomarc55]

I have two routers at home. A Speedport W 724V and a TP-Link WDR4300 with gargoyle 1.6.2 installed on it. I want to use my ddns for accessing the router and a nas remotely. I have set the ddns connection and opened the ports also nat pnp and upnp is enabled but I can't reach the router on the remote port.






In Speedport DHCP address reservation is enabled for the WDR4300.

With the stock firmware I was able to use ddns and I could reach the web ui of the speedport router but now I can't do it and transmission says its port is closed.

Thank you!





Up:
All settings was good, it was the Speedport's fault. The interesting thing is that I have changed only the adress lease time from 1 day to the maximum (3 weeks) and now the ddns is working. I think it's weird.
