My service provider is trying to conserve IP addresses they provide /31 point to point interfaces rather than the typical /30. This means that I can ping the other side of the interface, but I can’t ping the public internet from the router because the router uses the local wan interface my side of the /31 and that is only rotatable locally and not to say 22.214.171.124.
I am trying to upgrade my router, but its using the /31 IP also. My network is fine, because the router will forward packets through. I also can ping with at public IP as the source address rather than wan /31.
