Hello everyone,
I know that this question has been repated many times, but every thread I’ve read and solution i tried, I couldn’t get right solution
my problem is that I can’t access isp modem web gui (http) or ping.
topology:
ADSL modem(ISP)–>ethernet–>mikrotik router–> pc/phones (LAN + WiFi)
ISP modem has address 192.168.1.1.
on mikrotik i have added static ip on wan interface (ether1-WAN) 192.168.1.10
i have tried different src-nat, masquerade.
but somehow i cant ping or access webgui on ISP modem .
I CAN ping ISP modem using mikrotik inbuilt ping tool.


please post IP->Addresses and IP->Routes
also please post your filter rules.

Just by looking your IP addresses and without reviewing anything else I see that you have an IP address conflict between the two interfaces.
The /16 ether2 network has a complete inclusion of your /24 wan network.
Please review and separate the 2 networks.
