We use a cloud VOIP phone system at our small office. Recently, the border router of our cloud VOIP provider detected a port scan of their network from our fixed IP. The border router then blocked our whole IP which took our phones down. I suspect something on the network has some malware. I have two questions:
1. Is there a way to do outbound filtering on the MX100? What I'd like is to allow connections to our VOIP provider on only the ports that should be allowed, so the port scan couldn't hit our service provider. Or other suggestions on how to solve this?
2. are there any features or add-ons to MX100 to detect bad actors doing things such as port scans or DOS attacks from inside our network.
The Advanced Malware Protection and the intrusion detection/prevention that come with the Advanced Security license are awesome features. I've had AMP stop malware that hitched a ride into the network and the intrusion prevention has really opened my eyes to the fact that even small companies should be concerned with worldwide hackers.
