Lycan - My 4500 (using latest beta firmware) also has 24 limit MAC address. In my application this is a real problem so I am very interested to learn this is not a hardware limitation.
I understand from your email the 4500 will be limited by the number of other user defined entries made (DHCP reservation, MAC entry, schedule, port forward rule, QoS rule, all take away from the same memory pool).
I have tried disabling these features individually yet the 24 MAC address limit still seems to apply to my router. It would be very helpful to know what is the total number of entries the memory pool permits ( based on your post I'm assuming this spread amoung all of DHCP reservation, MAC entry, schedule, port forward rule, QoS rule)?? Does an entry to any of "DHCP reservation, MAC entry, schedule, port forward rule, QoS rule" each take the same amount of memory from pool? Lastly are there any other tricks or settings necessary to access full pool and extend 24 MAC address limit to something greater? And what is the upper bounds MAC address limit?
Thanks for assistance
