Hi, This might be an academic question in practice, but what is the correct configuration for sending towards a BGP routed subnet, or for 2 subnets communicating with each other? 44.131.14.252 is behind 44.131.14.253 44.130.121.1 is behind 44.130.121.2 This is the current behaviour. For the purposes of testing, packets sourced from 252 were encapsulated and 253 were unencapsulated. https://u4477715.ct.sendgrid.net/wf/click?upn=MJaTQVDJZogYIZySndf7y-2BCWLgZ… .1 sends directly to .252 and .253. .2 sends encapsulated to .252 and directly to .253. I would say packets to 1 or 252 should be encapsulated. I don't know if there is any point adding an extra header to something addressed to the gateway. Thanks, Mike, M6XCV
