Jeff, Since you are using bridge mode, try adjusting down the MTU supported through the network. We have observed that a realistic MTU for Verizon 5G home internet is about 1428 bytes. Good luck, Tom On Sun, Mar 19, 2023 at 8:00 AM <nanog-request@nanog.org> wrote:

Hello guy,
We recently discovered that any IP address announced by our ASN is blacklisted by Spamhaus, even if we only announced it but not use it.
I would like to ask if this is manually set by Spamhaus or is the system misjudgment? Has anyone encountered the same situation as us?
Best,
