Hi Everyone, I hope someone can help me, I have been trying to figure this out for two days. I have dhcp running on two ports for two networks. But they need to be able to see each other for server purposes. They unfortunately have to have seperate ip ranges for security reasons. How can I get interface 3 and 5 to talk?

Here is my current setup: Internet access is not a problem or needed here,the first network is on its own and working fine. Its the other two I need to get working together.

Your netmasks in the two networks don't match.
Your address on the interface states that it's a /24 network, the DHCP is telling the clients, it's a /22 network. In a /22 both are in the same subnet, so they won't use a gateway.
Adjust it in /ip dhcp-server network to be /24 and it should work.

An aside:
From the amount of interfaces I assume you have a CRS-series Switch.
You don't need to add all the interfaces to the admin bridge seperately - this will reliably max out your CPU when there's significant traffic.
It's enough to add one ethernet interface and set all the others to this as master port, so you have a hardware switch for this network.
Additionally, if you want the two networks to be fully routed, you don't need the icmp accept rules in the forward chain.

Thanks I will make the changes and test it now. I was hoping that the server would be able to see all the pc's of the network if it uses subnet /22. AND for the pc's to be able to access the server using the dns name (MyServer.local) instead of using the ip address. That is the reason I used subnet 22...is there a way to use subnet 22 on both interfaces and have the pc's be able to see each other? I can limit their interaction with other drop rules if that is possible.
Thanks for your help so far

OK, here is my new config: But the only thing that has changed is that I can now ping the mikrotik from both sides to both mikrotik addresses...49.254 and 50.254 from either network. I cannot acces the server from 49.0/24 or ping either networks pc's....

I see you have 10.80.8.1 configured as default gateway.
Is it possible that all the machines in the 10.80.8.0/24 network have 10.80.8.1 configured as default gateway?
In this case, they are sending their replies to requests from your 192.168.49.0/24 and 192.168.50.0/24 networks to their default gateway whicch seems to be unaware of those.
Either add static routes to 10.80.8.1 pointing for those two networks to 10.80.8.8 or give all machines these static routes.

Hi Chris, sorry for only getting back to you now. Holiday season and all keeping me busy.

The 10.80.8.1 gateway is another mikrotik with its own network. No physical pc's on the network has a 10.80...address. Only the mikrotiks.
Also the 10.80.8.1 network will not be accessed from my 192.168.49/50... range. That gateway is set for the other ports on the mikrotik that are mastered to sfp1.

Thanks
