RFS4000 act as router to cable modem?

[Nathan_Derichsw]

I am having difficultly getting an RFS4000 to connect to my ISP through my cable modem. I am new to AP controllers. I would assume(correct me if I am wrong) that the RFS4000 could replace my router. I also have 2 APs that I am going to deploy with the RFS4000.

Does not connect to internet: RFS4000 ---> cable modem ---> Internet
Connects to internet: RFS4000 ---> router ---> cable modem ---> internet

To my understanding using cable box in bridging mode will require DHCP, static IP or PPPoE on router side. All is supported on RFS (and any WiNG) device. Please start with DHCP like: interface up 1 switchport mode access switchport access vlan 2100 interface vlan 1 ip address dhcp ip dhcp client request options all ip nat outside Please also note that some services (like SIP) will require additional care because ALG provided in WiNG will not change packet headers as many home routers do. Also you will not expect upnp support on enterprise grade device ) Misha

do you have a lan & wan VLANs created on the RFS? can you share your configuration?

via shh provide the output of command 'show run'

You may need to reboot the cable modem to release the old IP/MAC reservation.
