Help w/ WIC-4ESW & DSL 1

[Board4aLiving]

I have a 1841 with a WIC-4ESW card. I need to program the 4ESW for a DSL line that has a static internet IP address from my ISP. Anyone have a config that could help me out?

is your DSL modem ethernet based ?
if not you need one that is

 

[Board4aLiving]

yes it is. I can plug my laptop into the modem and program the NIC for my static IP and all is well. Just need to figure out this 4ESW card

configure the private ethernet side of modem with a private address i.e 192.168.0.1 configure the ehthernet interface on the 4ESW with an adress in same range i.e 192.168.0.2

configure default route on router
ip route 0.0.0.0 0.0.0.0 <interface on router that is connected to modem>

The DSL modem is non-programmable. I have to program the 4ESW with the static ip that my ISP gave me. My internal FE 0/0 is set to 192.168.1.X. The question is that in the cli I can't figure out how to assign the 4ESW a address. Think of it like a 831 broadband router. The 831 comes with a built in 4 port switch that is assigned to E0. It also has FE 0/1, 0/2, 0/3, and 0/4 that you can program also. This is what the 4ESW is lacking. The fact that I can't program an address to the card itself like the 831.

ok then try this

connct the modem to Fa 0/1

get onto the router
go enable
conf t
int fa 0/1
ip address <static ip address from ISP> <SM>

Then use the default route command to send all foreign traffic out of that interface.

Tou may need a patch ethernet cable if the modem is expecting a client or does not have the cross button on it

That's just the problem. My boss purchased this router and the 4ESW card. FE 0/0 is going to be connected to the LAN. FE 0/1 is going to connect to our PBX (Phone system). I don't know why he purchased the 4ESW for the DSL line, but he says that it can do it. I wish I could use one of those FE ports....much easier

[schofs]

can you not use 3 or 4 ???
just replace the number on config ??

 

[Board4aLiving]

FE 0/0 & FE 0/1 are embedded in the unit. I tried assigning the static IP address to FE 0/0/0, the first port on the 4ESW, but it said I can't configure an IP address on a layer 2 link

try this
conf t
vlan database
vlan 1 name vlan1

interface vlan 1
description VLAN Internet
ip address <static ip address>
no shutdown

Interface fastethernet <connected to modem Int>
description Interface to Internet
switchport mode access
switchport access vlan 1
spanning-tree portfast


might be worth a go

Thanks, with a little bit of editing and adding nat to the interface, it worked like a champ. Thanks for the help!
