Connect 2 different connections

RouterOS General
1

It's been 2 days now to figure this out but no luck.. I have a HexGR3 MT, I want the computers/devices on two networks can see/ping/connect each others. From the MT terminal, I can ping all devices and gateways. From the devices, I can ping the gateway but not the other devices on both networks. Any help is highly appreciated.

Disregard the guest network, soon its for the wifi. I dont have firewall rules, only nat for wan.

Please post your config so that all can be revealed.
/export hide-sensitive file=anynameyouwish

(1) It may be possible but I do not recommend mixing up subnets as you have done!
If you need two main groups, the create two main subnets.

(2) Assuming the guest network is to remain Internet capable only (not able to talk to your two main networks.

(3) Please confirm eth1 goes to WAN
eth2 goes to? (device(s) and subnet(s)?)
eth3 goes to? (device(s) and subnet(s)?)
eth4 goes to? (device(s) and subnet(s)?)
eth5 goes to? (device(s) and subnet(s)?)

I appreciate you replied my post, thank you.. I’m really new to Mikrotik and I see so much usefulness of this device to our network. I’ve attached my exported configuration.
config.rsc (9.12 KB)
(1) Okay, I’ll try your advise.
(2) Yes, guest network is for internet only. Must not able to communicate with other networks.
(3) Ether1 goes to WAN, I can connect to internet on any interface/networks I created.
Ether2 is for future WAN backup. I’m planning to create a dual WAN setup.
Ether3 & 4 is our LAN, must see each other.
Ether5 is the guest network.

I have it working now… Windows firewall! :frowning:
