Hello User,

I have a problem with a CPM210. In the neighboring house we have installed a FritzBox 7390 for access to the Internet via DSL. Since the WIFI radio link is about 500m up to us in the house, I have a CPE210 installed and configured as a client. At the output of the CPE210 is a Raspberry as a router and access point. The configuration looks like this:
IP FritzBox 172.30.2.20
IP CPE210 172.30.2.21
IP Raspberry input 172.30.2.22
IP Raspberry output 172.30.1.22
In the FritzBox is also a static route to the network 172.30.1.x deposited and sends everything to 172.30.2.22.
The configuration works flawlessly for all clients via the Raspberry. All devices can log in and work easily on the Internet.
Since it is a house abroad, I also have to access from outside. The goes already problem-free up to the Fritz box and to the CPE210 (172.30.2.21). I reach however no connection to the Raspberry on the IP 172.30.22. What can this be? Why does not the router send the packets ????
If I log in via the WLAN of the Raspberry, everything works perfectly! Only external access is not possible! If I connect the Raspberry directly to the Fritzbox without CPE210 everything goes without problems! The CPE210 must be the problem! What am I doing wrong?
