Switch behind mikrotik RB750 does not work

RouterOS General
1

Hello,

on the wan i created 2 vlans. one ist vlan 10 with the ip 192.168.1.1.
then i create a vlan for the lan side (vlan 99) and made a bridge with ether 1. the ip is 192.168.2.1.
when i connect my pc to ether 1 i can reach the network 192.168.1.1 but when i connect a switch to ether 1 and then connect my pc to the switch i cannot connect this network. if i connect a second pc i althoug can´t connect the network 192.168.1.1 and my first pc. when i use a hub instead of a switch everything works fine.

where can be the problem?

kind regards

kangoo

Hi there,

it sounds like the switch is not setup to bridge the ports correctly currently, have you tried resetting the config on the switch to default and connecting it up to ether1?

If it works directly connected and via a hub then your Mikrotik configuration should be fine, the issue is directly related to the introduction of the switch to the network.

Hello,

it´s not the swith! The switch is unmanaged and works fine if i use a Cisco Router instead of the Mikrotik.
