I am using RouterOS v3.11 in a hotel, I need assign different vlan id to each room to identify purpose(this was request by the Government).
I am using hotspot + dhcp-server to serve the guest, and don’t want to let guest type user name and password to access the internet,because the hotel don’t charge the network fee.
So, I try to create 500 vlan(this hotel has 500 rooms), and then create an bridge named “bridge1” to bridged all the vlan, and then setup the dhcp-server and hotspot server on the “bridge1”, i drop all the packet forward between vlans.
This configuration worked fine, when the vlan number is about 100, but when the vlan number over 200, then whole system become very unstable, the guest can’t ping gateway, can’t browse some web site, can’t ….,
I have work on this case for a long time, I have try to setup an powerfull computer, but still can’t work property. And now I notice some secret:
1.when I add more than 247 vlan to bridge, the /bridge/hosts become chaos. Some port hasn’t add to this bridge will appear in the hosts list.
2.if I using the bridge, I can’t resolve “kappa.url.com.tw” mx record.
These must be an BUG OF BRIDGE module, so I report it here, Mikrotik’s please solve it ASAP. I hope it will be fix in 3.12 release.
By the way , i am using RouterOS about 2 years, so , i am not a newbie:-)
