Hi everybody,
in a initial state of the router (mikrotik hex RB750Gr 3) I can access to internet through port 3 with input to the router in port 1.
Then I just change the mikrotik IP ( from default 192.168.88.1 to 192.168.1.7) and, consequentially, also the DHCP according to the new address to 192.168.1.20-192.168.1.251
(instead of 192.168.88.10-192.168.88.254).
But no more internet signal pass through the mikrotik router.

What else do I have to change?

Thanks in advance.

Have you looked at firewall settings? Do they use 192.168.1.x instead a.b.88.x?

Your WAN IP address range and LAN IP address range are the same:
192.168.1.x I believe that can not work well.

Try something different...

It seems to me the address are right in the firewall setting page.
This is my pc IP (given by the mikrotik router 192.168.1.251 )

What are NAT rules and Firewall?
Connections shows that there is some traffic from LAN to WAN ... do you have DNS properly configured?

Yes, it seems the problem was exactly this one.

Do you say this because of the number that there ara in the LAN (src. Address) to the WAN (Dst. Address) lines?
