Hi all
Firstly I would like to give some background. I am based in Spain and I recently merged my wireless network with another company. The new network consists of Ubiquity client units connected to a mixture if Mikrotik AP’s and Ubiquity AP’s with Ubiquity back hauls, all in transparent WDS mode, and a Mikrotik Rb1200 gateway. The company I merged with use the following network configuration. Core network including the client units have preassigned DHCP private IP addresses (192.168.100.xxx) the client routers (PC’s if no router installed) have public IP addresses. Over the past 2 weeks or so customers have been experiencing intermittent loss of internet access for between 1 and 20 minutes and powering their equipment off and on does not fix it. This is happening on a fairly random basis and while one (or more) customer is down everyone else is working ok.
I am concerned about the current configuration with customers routers using public ip address’s and are connected via a transparent network. This in my opinion leaves the network wide open to deliberate or unintentional attack from users. (eg a customer unintentionally plugging the WAN cable into a LAN port and thereby putting the routers DHCP server onto the network)
I have my own opinion but I would really value the opinion of the forum members as to the configuration of the new network.
