One lan port with two subnets

RouterOS General
1

Hi! I have one lan port connected to switch with one subnet 192.168.0.0/24 and dhcp server.
And I want to add second subnet 192.168.1.0/24 for some clients on the same switch with static addresses in that second subnet.
Is this possible?

Yes, it will work. Just remember that there won’t be any real isolation betweet two subnets, e.g. any dhcp client can simply set static address and access devices in other subnet. In case you’d have managed switch, you could use vlan to isolate subnets.

I’v tried to add second address to local bridge, but then I set address from that network on my pc it doesn’t work. Can’t ping gateway or anything else.
What is the right way to get my config working?
And I don’t need isolation, just free to use subnet for temporaly cases.

The way you describe what you’ve done, it sounds right. What is your new IP address and subnet on the local bridge? What IP did you assign to the PC?

If you’re on win try switching network type to home or work ( but pings should work fine anyway).
This might be also a result of firewall dropping packets from unknown subnet but that’s depends on your FW setup at router.

Too many if, need more data [emoji41]

Nothing special is required. If you previously had e.g.:

/ip address
add interface=<LAN> address=192.168.0.1/24

and you added:

/ip address
add interface=<LAN> address=192.168.1.1/24

Then when you connect device with e.g. 192.168.1.2/24 (or 192.168.1.2/255.255.255.0 in Windows terms), you must be able to ping 192.168.1.1 from it, unless you have some firewall rules preventing that. And if you add 192.168.1.1 as that device’s default gateway, the internet access will probably also work (but it depends on exact NAT rule used).
