I have a customer who has taken a 3800 router with one HWIC-4ESW card on it. He has used up his on board ethernet ports to connect his LAN and VPN. He has used the port on the HWIC for connecting another WAN ethernet link of his. But due to hardware limitation the HWIC learns only a 200 MAC on the whole of the HWIC module and beyond that starts dropping the packets.
Do we have any other WAN card that can take in RJ45 ethernet links into it and yet have no limitation on the MAC addresses that can be learnt over it ?
