How about arp packets?

No.

ARP is intended to translate addresses in the local
subnet only.

For IP packets destined to other subnets, the routing
layer has to supply a gateway address in the local subnet.
The gateway is the ARP'ed for.

Proxy ARP means that the gateway is able to respond to
the local ARP request on behalf of a destination host
behind the gateway. The ARP is local even in this case.
