I understood Hans's "gateway" to refer to the default gateway setting of 
each computer.

Contacting other computers by their IP address should still work in most 
common setups, provided the addresses are in the same subnet.

Admittedly, the OP didn't explicitly specify if pinging was done by IP 
address or DNS name, and indeed, DNS is more likely to depend on the 
residential gateway (instead of /etc/hosts or mDNS).

Kind regards,
Andrei
