Hi Brendan,
Not sure if I understood your question well. If you want to avoid the
gateway hop, you can just configure NAT rules with "dnat_and_snat" to do
distributed NAT.
'reside-on-redirect-chassis' and 'redirect-type' don't seem to help for
your use case because you mentioned your VMs are in overlay, while those
options are for VLAN based logical networks.
Thanks,
Han
