Re: RouterOS freezes if I change the IP

You're changing the IP address of the router that you're accessing it via. So as soon as you change the IP your connection to the router is lost. If you change the IP on the router, and then the IP on your PC, you should be able to reconnect. Look into using "safe mode" so you don't get locked out n...

Using the latest bridge vlan implementation, is it possible to drop untagged traffic?

Re: Allowing 100 sip connection to pbx

What are you trying to achieve?

Limiting to 100 connections in this way makes you susceptible to a DoS attack. Any SIP device on the internet will get scanned multiple times a day by various bots, which could exhaust available connections and block genuine clients.
