need assistant

i have two different ip on my router
ISP with X.X.X.254/24 on ether1 (private IP)

with x.x.x.241/29 on ether2.
ether2 to ether5 was master-port

please i want to route a private ip 192.168.10.1 to my switch through ether5 to access internet

any help please

Please clear your point with export file.

/ip firewall nat add chain=src-nat src-address=192.168.10.1 out-interface=ether1 action=masquerade

Please note, I did not fire up a login to a MikroTik to test the above syntax. That rule may need a fix or two.

That rule intends to give exactly one private IP of 192.168.10.1 access to the Internet via NAT to the public IP on ether1.

If you want the all IPs in 192.168.10.0 through 192.168.10.254 to be able to access the Internet, you would change the src-address to 192.168.10.0/24.
