857w - Ethernet ports - are diff subnets possible?

[imbadatthis]

alright dont ask me why this happened im still soar from the b*tt hurt I got from my current ISP.
need to know if the Ethernet ports on the 857 can be on different subnets?
ie can i do :

ISP ---> FA0-857w(DHCP , real IP) ... FA1-857w---> (private IP).

or configuration wise: FA0 --> Bridge-group 1 and FA1--> Bridge-group 2


is this possible ?

Yes, first you configure your ports into different VLANs:
interface FastEthernet0
switchport access vlan 10
spanning-tree portfast
interface FastEthernet1
switchport access vlan 20
spanning-tree portfast


Then, you configure an IP address on each VLAN interface (or BVI interface for wireless VLANs), eg,

interface Vlan10
description LAN1
ip nat inside
bridge-group 10
bridge-group 10 spanning-disabled
interface Vlan20
description LAN2
ip nat inside
bridge-group 20
bridge-group 20 spanning-disabled
interface Dot11Radio0.10
encapsulation dot1Q 10
bridge-group 10
bridge-group 10 spanning-disabled
interface Dot11Radio0.20
encapsulation dot1Q 20
bridge-group 20
bridge-group 20 spanning-disabled
interface BVI10
description LAN1
ip address 192.168.1.1 255.255.255.0
ip nat inside
ip virtual-reassembly
interface BVI20
description LAN2
ip address 192.168.2.1 255.255.255.0
ip nat inside
ip virtual-reassembly
bridge 10 route ip
bridge 20 route ip

int f0
no shut
int f1
no shut

service dhcp
ip dhcp pool VLAN10
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
ip dhcp pool VLAN20
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1


Ummm, that's about it - of course you have to worry about your WAN interface, too, and also configure access lists on it. And your encryption & SSID config.

I'll try to dig out an old config I have from installing one of these for somebody.

unfortunately the 857w doesn't support multiple vlans... so that wont work.

i've been fiddling around with it abit here and there, doesn't seem like its possible the normal way .
ie: it doens't support ip addressing on each interface since they are just all switch ports. ...

thank you never the less for taking the time to write it up

The old config I have is for an 871W. Sorry to hear this doesn't apply to your model as well.

yeah I should have gone with the 87x series.. but it was more expensive than the 857w... lesson learned i guess...

thank you for trying to help
