Connecting Chargee-Sparky in Home assistent dont work

Hello,
-I run home assistent On a NUC and is directly connected to my router Xyxel T52
-I Connected a P1 Sparky to my slim energy meter using the P1 port
-I installed the Chargee app and connected it to the Sparky P1 and see the ipaddress 192.168.68.119, DSMR 5
-In Home assistent I used the DSMR Smart reader plugin, and uses the Ipadress 192.168.68.119, port 3602 and DSMR version 5
-BUT the connection failed, why?

-I connected TPLINK with a cable to my router Xycel. All the wifi connection are connected to TPLINK, but the DHCP server give ipaddress in the range 192.168.1.x
-Do I have to create a NAT rule??? on my Zyxel router?

Regards henk
