Seconding this. It's a very irritating implementation detail of Comcast Business service. It can be worked around of course, if you have a VPS somewhere close-ish with a static IP you can do the whole WireGuard tunnel thing at the cost of some extra moving parts and maybe a minor latency hit. And while overall their business offering is certainly vastly better than their consumer shit, if you're on their router they're still jerks. I've noticed their own pushed WiFi keeps switching itself back on for example. Overall it reinforced my desire to use absolutely anything but Comcast whenever possible, though when it's not I'd still pick business service of consumer service.
