I recently got Telstra NBN connection. Since I run an email server from home, i needed the static IP and they haven't still provisioned that yet.
But the IP that I am getting at the moment is not changed and it stays the same even I reboot the router so many times.
From yesterday, the emails stopped incoming emails. Port scan says no port 25 has opened. Surprised !!!
Up until yesterday it was opened and all of sudden it is closed.
Does Telstra block 25?
I logged on to the Telstra and saw Broadband protection. Is it something to do with port being blocked?
