Hi all
In the end we’ve got it working. Following the missing steps from ConnMan.
Supposing the WiFi is online and ETH is ready

The routing table, as correctly pointed out by David are not populated
correctly.
root@ale:/home/alessandra# ip route show table 256 (empty)
root@ale:/home/alessandra# ip route show table 257
default via 192.168.43.1 dev wlan0
Adding than the following:
root@ale:/# ip route add default via 192.168.1.1 table 256
root@ale:/# echo 1 > /proc/sys/net/ipv4/ip_forward
root@ale:/# for f in /proc/sys/net/ipv4/conf/*/rp_filter ; do echo 0 > $f ; done
root@ale:/# echo 0 > /proc/sys/net/ipv4/route/flush
and especially the following two lines:
root@ale:/# iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source
192.168.1.100
root@ale:/# iptables -t nat -A POSTROUTING -o wlan0 -j SNAT --to-source
192.168.43.26
I’ve got now:
wifisession@:~$ curl ifconfig.me
5.170.189.246 (wifi)
ethsession@:~$ curl ifconfig.me
80.21.33.250 (eth)
i.e.: the routing is correctly done discriminating UID.
