i have two interfaces eth0 and wlan0. With wlan0 i am connected with an AP that has access to WAN, i receive an IP adress via DHCP coming from the AP.
A second interfacae is eth0. I configured it using an dhcp server giving out a different subnet ip adresses to all clients connected in that subnet via eth0.
My client device (smartphone) is getting an ip adress from my eth0 dhcp server correctly.
However I struggle to connect now eth0 with wlan0.
eth0 network is 192.168.42.0/24. My pc having both NICs uses 192.168.42.1. My ip adress from wlan0 is lets say 172.22.3.193
What I already did is enable ipv4 forwarding, but without success. My phone says there is no internet connection but can connect to eth0. It seems i have to setup certain iptables rules to get forwarding to work but I tried different approaches i could find in the net and none of it works.
Any ideas on what to do next?
Edit: My route command gives me this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default www.go.wlantick 0.0.0.0 UG 600 0 0 wlan0
link-local 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
172.22.0.0 0.0.0.0 255.255.0.0 U 600 0 0 wlan0
192.168.42.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
It seems to be a route issue. Can you provide the output of
ip route
