Hello everyone,
I am running into an issue that seems to apply to different devices.
The topology is below. The first model is having issues, and the second one is working just fine.
Medical device(172.x) -- switch -- A PC with dual NIC(172.x, NAT 10.x) -- Meraki MS250 -- MS425 -- Cisco C6509E -- Servers(10.x)
Medical device(172.x) -- switch -- A PC with dual NIC(172.x, NAT 10.x) -- Cisco2960x -- Cisco C6509E -- Servers(10.x)
The PC that has dual NIC acts as a software firewall. It has IP from the company network(10.x) and IP from the local network(172.x). I was also asked to assign a company IP(10.x) to the Medical device. The vendor engineer did some kind of NAT setting on the firewall PC.
Issue symptoms:
Medical device(172.x) is not able to ping Server(10.x) if the network path has a Meraki device.
Another engineer did some packets capture, and he was saying it looks like some broadcast packets are missing.
I think this is an L2 issue, and no router exists in the physical path.
