I have read the basic configuration wiki , following which I configured my x86 routerOS as the following:

ether1 : wan
192.168.0.102/24

ether2 : lan
172.25.19.1/24

setup default srcnat

and ran a DHCP server on ether2

but now I can ping 8.8.8.8 from ether1 but not from ether2

why my srcnat not working?

I have attached a screenshot of these configs

On command prompt on your pc run "ipconfig /all" and come back with network settings.

src-nat is working as packets are Firewall Filters. If needed, disable all drop rule and test again. You should find where the problem is.

Hi,

I assume you can ping the internet from the router itself?

Can you ping 192.168.0.1 from lan?

What happens if you do a traceroute?

It could be the dhcp address on ether 1 causing you troubles.

Turn off dhcp client and then assign 192.168.0.102/24 to that interface
