(English) connect network as WAN to experia box v10A

Hello,

I have an experiabox V10A at home, and I am trying to connect another router as WAN to it - but it doesn’t work. i know it is not a problem with the other router as it can connect to my office network no problem, but with the experiabox the connection times out. I think it might be a dhcp issue.

Here are the system logs:

… and it continues like that for a while. The IBR200-04d is the router I am trying to connect to the experia.

Would you be able to provide any help? Thank you very much!
