Re: 1751 for a cable router

I don't think this is possible. The only ADSL-related WIC cards the 1750 will support are the WIC-1ADSL, WIC-1SHDSL, WIC-1ADSL-I-DG and the WIC-1ADSL-DG.

Re: 1751 for a cable router


I don't know if this will work for sure but it looks like you will have to connect your cable modem into your ethernet port and configure the ethernet port to receive a DHCP from your cable provider like this:

router(config-if)#ip address dhcp

Then you'll probably want to create a default route towards your ISP (default gateway):

router(config)#ip route e0

Configure your fastethernet interface (LAN):

router(config-if)#ip address

After that you'll probably want to specify set up DHCP on your router:

router(config)#ip dhcp excluded-address (excludes your f0 ip)

router(config)#ip dhcp-pool INSIDECLIENTS



router(config-dhcp)#dns-server (or your ISPs DNS server)

routeR(config)#no ip dhcp conflict logging

Then setup PAT:

routeR(config)#access-list 100 permit ip any

router(config)#int e0

router(config-if)#ip nat outside

router(config-if)#ip nat inside source list 100 interface e0 overload

router(config)#int f0

router(config-if)#ip nat inside

I've haven't set this type of configuration up before, but this is where i'd start.

Good luck :)
