I am using an 871 to connect to an ISP that requires my outside inteface to be in DHCP mode. I give the ISP the MAC address of this interface and my "static" IP is assigned via DHCP based on this MAC. Now I need a second IP and the ISP is asking for a 2nd MAC?! Is it possible to do this? I realize that I could have the ISP route a public block of IPs to my first IP but this setup is in a South American country where that option is not available. Any ideas?
