Pi router

Pi router subnet (eth0) 192.168.1.0/24 - forward traffic to 192.168.8.254 (wlan0)
pi router ip (eth0) 	192.168.1.254
my pc					192.168.1.245

---------------------------------------------------------------------------

from pi router - I can ping:
	google 			8.8.8.8
	my pc 			192.168.1.245
    actual router 	192.168.8.1

from my pc - I can ping
	pi router		192.168.1.254

	over actual router wifi, I can ping pi router aswel
------------------------------------------------------

Problem: Pi is not forwarding traffic between interfaces or simply forwarding traffic
