kernel: IPv4: host 192.168.1.29/if2 ignores redirects for 192.168.1.6 to 192.168.1.6
I have the messages above in the log on Edgerouter X. If they occur then Hairpin NAT does not work for the connected device 192.168.1.29 .
192.168.1.6 is a Debian server with DynDNS and Port 443 ist forwared . If i call the DynDNS adress internaly over Wifi with my Android Device - 192.168.1.29 i can not reach it. However, it is rare and then works for a time correctly .
Additional info: I have a Netgear R7000 as Access Point on 192.168.1.20 . Meanwhile, I noticed that I can connect me via WIFI only one device (Tested with Macbook Air, Chromebook, Android Phones) on the Debian server ( 192.168.1.6 ) via hairpin NAT on the DynDNS address . The other devices show a connection error.
In summary : Only one device at the same time, whether cable or Wifi can internally connect to 192.168.1.6 by DynDNS Adress xxxx.mynetgear.com.
Please can someone look at this.
