Hello - we have Microsoft troubleshooting a DHCP-related case for us, and they're seeing traffic coming from an IP address that is tied to our ASA gateway firewall. There are 2 subnets going thru our network, so there are 2 IP gateway IP's associated with our firewall - 192.168.1.254 and 192.168.5.254. They're asking for the MAC address of the 192.168.5.254 IP. How do I find this? I'm trying Experts Exchange to see if its faster than asking Cisco. I've Googled it for 15 minutes and am not finding the answer so far.
