I confirmed this issue only appears when running port scans from outside of Sonic's network and that it also affected at least one other Sonic customer, both by testing with my neighbor's Sonic connection (with their approval). Sonic initially informed me that they were investigating the issue but eventually told me this week that they can no longer investigate it. I am still waiting on a response as to why this issue is being closed, their last communication seemed to state that they do not see these ports as open though I still do.
I'd like to put this out to the community to confirm that it is or is not a widespread issue and, if it is, make the case to Sonic for continuing to investigate and resolve this. I'll assume that most in this forum are literate in networking and can run a port scan themselves so I'll just lay out the criteria to have in place for testing to replicate this particular issue. If anyone needs specific technical assistance with running a port scan just ask, I'm happy to help
To replicate this the following should be true:
- - you confirm your current public IP provided by Sonic
- your router/firewall is powered off and disconnected from any Sonic equipment
- your fiber ONT ("fiber modem") is powered off and physically disconnected from any ethernet connections
- you run a port scan for ports 80 and 443 against your current Sonic public IP *from outside of the Sonic network* (this is key as I've confirmed that a port scan of my public IP from my neighbor's Sonic connection does not show the ports as open)
If you've met all of those criteria and you see ports 80 and 443 respond as listening/open, then you are also affected by this.
I understand that some may say this is a non-issue if I've confirmed that my firewall does not actually have those ports open but I would respectfully disagree. The current state of affairs makes confirming the security and functionality of my network more difficult and as a network engineer myself I would be concerned about an issue like this on my network that I could not explain. This is already a long post so I'll leave it there lol, thanks for reading.
