Proxy-Arp only works if monitoring external interface
Configuring a new srx220 with proxy arp. ISP gives a /29 to use. I have both static nat and destination nat configured for some of the ips I have setup with proxy-arp. None of them were working at all, however when I issue the command:
monitor traffic interface ge-0/0/0.0 no-resolve
Proxy arp magically works for everything as long I have the monitor command running.
