I cannot access internet on LAN port neither can ping my WAN ip

[nshikalgar]

Hello there, i am fedup with this issue, dont know how to resolve here,

I have a router ISP one
from there the connection goes to my opnsense machine to WAN port
ISP router has DHCP configured on 192.168.1.1/24 subnet
from there i got my WAN ip also note on ISP router there is NAT enabled

Now my LAN has another subnet configured 10.0.0.0/16
now this connection is connected to my pc and i use my pc to configure opnsense
i can ping my opnsense machine on 10.0.0.1, which is same on my pc network as we are both connected

but why cannot i access internet from my pc
i have fresh install of opnsense, no anything setup yet which can ruin
also i have configured DNS to 8.8.8.8 and from my OPNsense machine i can ping 8.8.8.8 and 1.1.1.1
so my opnsense machine is getting internet

but what happens to my LAN port
and why this happens

I am trying again and again everytime i fail, its been 20 days

Please any one here to help

Thanks
