Hello,
I am changing ISP's and they need my MAC address to assign my static IP.  I do not know how to discover what my outside MAC address is for my Cisco ASA 5505.  I currently have the outside port on VLAN 2 port.  I also have the Cisco ASDM installed on my connecting computer.  I can both telnet in and access from the web interface.  I am currently out of town, so I cannot look at the bottom of the box, if it happens to be written down there.

I used netscan to try to determine my MAC address on the inside port, and then called my current ISP to see if they could see my MAC address on thier ARP tables, and the MAC they gave is the same MAC I see on my inside port.  Is that correct?

Hey

From the command line - type
sh interface

Look about 3 lines down from the interface and it will tell you your MAC-Address

cheers

Why is the MAC address for the "inside" interface the same as the "outside" interface?

If you are using vlans you may have split the interface into 2 seperate logical vlans but will share the same physical mac address.  If not - they should be different - but only 1 character different
