Pfsense is not connecting to internet

lan ip :192.168.100.1
wan ip : 192.168.10.175
default gateway:192.168.10.1 (yes , a private network)
host ip : 192.168.100.2
i am able to ping lan ip and wan ip from host , and i am able to ping host from pfsense .
but people in 192.168.10.0 network unable to ping my wan ip
actually default gateway is working (192.168.10.1) all other devices connected to it are getting internet . but pfsense shows the default gateway is offline . i checked the cable connecting to wan interface of pfsense ,it works fine .
natting is good
i also wrote pass any any rule in both wan and lan
still unable to get internet

This defaults to on, turn it off

The Block private networks option on the WAN interface automatically puts in a block rule for RFC 1918 subnets.

i unticked them already … still no internet
