I think they may be talking about evil ISPs who change TTL of all your incoming IP packets to 1 so that any router you may run would drop them. However, this is not an issue with "dumb" ethernet-WiFi bridges.

Hm, is this something that can be shaped?

Not sure what you mean.

Obviously it is possible to increase the TTL of incoming traffic if that's what you wanted to know. Linux iptables can do that, IIRC BSD pf too, and some consumer routers even have an option in the GUI.
