SMC business class gateway in bridge mode with Static IPs
I am trying to use the firewall, VPN, VLAN etc. features on a Cisco 881 router instead of those provided on my SMC business class gateway.
However, I am confused as to how to proceed with this while routing my public static IPs (I am paying for 5 from Cocmast) to devices behind my Cisco 881 router's NAT. I am no expert at this, but it seems that I cannot put my SMC gateway in complete bridge mode (i.e. disable its NAT) since it would not be able to route the public static IPs.
Can someone please confirm to me the appropriate approach and the pros/cons?
