Hi,

The device's FE ports are Layer 2 only and it's used for the LAN. Use the ADSL (POTS) for your WAN connection.

Hi

Thanks for the reply

But I need to connect two WAN links, there is only one ADSL port available with the router.

Can I connect by creating two seperate VLANs(SVI) with WAN IPs and add these L2 ports to the VLANs.

Will it work.

Hi Naresh,

Actually the Cisco 876 router has the following ports on the back panel:

Four 10/100BASE-T RJ-45 Fast Ethernet LAN ports with a built-in switch
One 10/100BASE-T RJ-45 WAN Fast Ethernet port
One ISDN S/T port
One ADSL-over-ISDN port
One RJ-45 console port

If the another wan link is ISDN type then you can use the ISDN S/T port it seems.
Connect the wan link to any interface then create a vlan and assign the wan link IP and do routing as possible.

I think so the above should work, because I have the same kind of setup. What I did is...
I have connected the WAN link to L2 port and create a vlan in router for the routing purpose.

Please rate all the helpfull posts.
Regards,
Naidu.

This is NOT correct - there is NO FE WAN INTERFACE on the Cisco876.
