Same subnet but cannot access server HELP!

RouterOS General
1

Hello I need help. I created 1 network 10.0.0.1/22 and the dhcp gave me ip pool of 10.0.0.100-10.0.1.254.
Now, we have a linux server from another office in another location which has the ip of 172.16.10.254.

The problem is that all devices that has an ip of 10.0.0.xxx can access the server BUT devices that has an ip of
10.0.1.xxx cannot. Why is that? I am using gre-tunnel which has ip address of 10.200.1.1/24 from router A and 10.200.1.2/24 from router B

Tracert from 10.0.0.xxx ip devices shows 10.200.1.1 but tracert from 10.0.1.xxx ip devices show nothing.

Thank you for your help folks! Cheers

Was it your intention to assign only half the space to DHCP? A /22 subnet spans 10.0.0.1 to 10.0.3.255.

What relevance does that have here? Your later reported symptoms don’t bring that into it at all.

That sounds to me like someone has a 10.0.0.0/24 subnet configured, not /22.

If that’s not it, then you should post your sanitized configuration /export output here for us to go through.
