static route?

RouterOS Beginner Basics
1

I’m new using mikrotik. I read the manual and documentations which were very helpful but now i have a big doubt.

My provider give two different subnet /25 but I use only one /25 with some subnet for different customers. so far I have routed a subnet /27 to one client. but now my client need this /27 an the other /25 i dont know how can i route the new subnet /25 in the same ethernet.

I have a routerboard with 9 ethernet. Ether1 Public with proxy-arp enable so i configure the /27 in Ether2(customer). now I have to setup the new class /25. can i put some static route without using an ip on the mikrotik or i need to use bridge?

Ether2 (customer) 200.43.XXX.XXX / 27
new ip 190.220.XXX.XXX / 25

could someone help me with this?
Thanks in advance

if it were me i would ask the ISP for a /30 routing subnet. Have them ‘route’ all your subnets thru that /30. No need for proxy arp, just route the IPs where you need them. Making expanding easier down the road. The ISP probably prefers this method anyhow.

I understand your point of view but is not the solution. in the first subnet /25 I have multiple subnets /30 /29 /27 and one of those subnets is on the ethernet client who always use. now I need to point to the same ethernet a new subnet /25 which has a different range of ip. But I want to do this without using a gw defined in mikrotik. can i route all without taking any ip?

What would be the way to implement it?

Thanks
