Hi there,

I have an OPi3 box that acts as home surveillance server.

It has WiFi configured as AP, client is Android phone with static IP/routing and IP Camera software.

Problem is, that there is NO IP routing. I CAN access video / pictures from phone on OPi box, but NOT from my LAN.

Below is routing table and iptables. Looks ok but not working.

I am able to access (from LAN) WiFi IP of OPi. Also can access video served by "motion" software on OPi. But no direct connection to Android phone.

Please confirm IP forwarding is enabled

@laurentppol  :  asking just out of curiosity , can you elaborate more on your this "Surveillance server" ? Which type of external storage attached to OPi3 for IP camera videos/images ? which open source surveillance software used and its configuration ? Number  of IP camera(s) used and their types ?  and about over all performance and satisfaction level for this whole setup ?

@laurentppol  :  asking just out of curiosity...

Storage - external USB->SATA HDD, 320GB, about 2GB/24h @ 1fps, software: motion, set to permanently record at 1fps from IP Webcam on old Android phone (Xperia L), image set 1280x1024. Plus cron replica to remote storage every 10min (WiFi link). Separate WiFi network (different channel from other apps for performance reasons, this is why I have set up OPi3 as AP and want routing). Satisfaction level: very high :).

 

lanefu: THX very much.

Ooops, not so fast:

httping works (to telephone, Android does not respond to ping), but using browser I get to.... OPi3 HTTP server, NOT phone.

iptables are just clear.

 

How to solve this?

Looks there is a problem with one of my routers, not OPi3... Small change in routing scheme and I get WWW from IP Webcam on phone.
