Is this new?

I just noticed this in my account under the family filter.

Hi there,

Yep this has just been implemented. Filtering is turned on by default but can be turned off if need be via MySlingshot

Cheers!

So thats why access to my home server stopped working..... Been puzzling me for a few days

Nice idea to keep the cruft off my (very low bandwidth) inbound connection.

Any way to block all ports except just 443 ?

Blocking HTTP/S, FTP and SSH? that's an interesting one...

the HTTP/S and SSH ones will be to stop the various DVR/webcam/plex/NASes/router's that people keep putting on the internet with no/crap passwords or leaving them unpatched, from getting owned.

I don't think you can unblock just particular ports on Vocus ISPs, it's all or nothing. You should be firewalling the rest of your stuff yourself if you want a particular port open to the internet!

From a security perspective this default blocking is a great thing. There are a lot of compromised CPE's/IoT devices/etc around, even in NZ that send out spam/MITM your traffic/are used to DDoS people and compromise other peoples stuff..
