ip forwarding with different vlan

hi

I want to forward IP from the IP range 10.0.3.0 to access this IP range 192.168.21.0 with different VLAN

please provide the way using the router UI not terminal

note: both of them are on the same local network

thank you

So both networks are attached to the same router?
If so and the config is default-ish, it should automatically route between the networks without any user action required.
Your question was a bit ambigious, either a language barrier or typo - or not precisely put. I read your “won’t” as “want”
In case your statement “won’t” means “do not want to”, you’ll need to block this in the firewall filter chain:

/ip firewall filter
add action=drop chain=forward src-address=10.0.3.0/24 dst=address=192.168.21.0/24
add action=drop chain=forward src-address=192.168.21.0/24 dst=address=10.0.3.0/24
###adjust your network sizes accordingly if necessary.

Hi sir Chris,

How about if like in my case. I Have multiple separated VLAN such as:
vlan 10 - Admin network (offices, workstation,servers and network equipment)
vlan 40 - Dormitory WIFI
vlan 99 - Guest WIFI

How could i access internal IP’s within vlan10 from vlan40? Incase that i’m in dormitory and i want to access database server from vlan10 while
currently connected to dormitory’s wifi(vlan 40)?

TIA! sir.
