Hi there

I'd like to post an issue that- i think -.. a lot of mikrotik users experience

i have an RB1200 used as a hotspot gateway in a large lan

Subnet/22
DhCP IP addresses 10.0.0.2-10.0.2.254

when mikrotik is on

It's to hard to communicate between a pc and another (or a ubnt device with an ip on the same range) on the same lan (http or sharing) even when the addresses are (for example) (10.0.0.5-10.0.0.10)

sometimes the connection works , some times it freezes
the same with pinging .


when mikrotik is off

I'm able to communicate with all pcs and devices on the lan with no single disconnection (untill devices loose their DHCP lease)

i tried to use the filter rule that allows all connections through the local interface to be passed ... no news

how can i get my inter-network connectivity stable in the presence of mikrotik hotspot+DHCP


thanks

A network diagram would help and it would help to know what traffic levels you are seeing on the RB1200 interfaces when it is on.

seems like you set 'address-pool' for Hotspot - set it to 'none'

with ip pool set, Hotspot uses ARP poisoning technique to serve clients with wrong network settings

Thanks .. helped a little although i still got some inaccessible devices ..

How about something like this:
Or if you want this to apply to all of your hotspot servers (incase your running more than one).

Maybe if you separate the hotspot on another interface using VLAN, it should stop messing with your other devices. But I can be wrong about this!!!
