Hi all,
I have a DMVPN network with ISR4331 routers and wanted to do packet capture on LAN interface on one of the spokes. Unfortunately I get only ingress packets on that interface; pings go through but I can only see ping responses, not requests. Is it some kind of bug or do I do something wrong? IOS-XE version is 16.9.5, device in LAN on Gi0/1/0 has address 10.0.28.66, my workstation (outside of DMVPN network) has address 10.10.195.122.
