I think that problem not in openwrt. I remove carambola and connect ethernet add-on to auvidea encoder E10. But still cannot access it on default address.
But... May be you can help me to get it from carambola...
Host Debian 9 192.168.8.1/32. Through WiFi router by ethernet at 192.168.8.1/24 which through WiFi 192.168.2.154/24 connect to Carambola2 at 192.168.2.1/24
According docs there i can access auvidea H264 encoder E10 at 192.168.0.160/24 :80, :22, :554
E10 must give web-panel and SSH access. Through them I want to configure camera MP1010M-VC ang get videostream from it.
