Cisco 2501 / adsl To Internet

| I'm new at this.... So, I may need a bit of help. Can one connect a 2501 to
a dsl line from an ISP.
Do I need to use NAT. or something like that, or can I just config thr
router with a secondary IP or one IP. If I cant use a 2501 what is a good
2500 to use for this. I have a 1912 and that works fine. But I just cant
seem to get the routers to send packets to the dls modem and back. I think
I'm missing somthing.
Thanks for your time.

| Does the DSL modem have an IP address? If so, you will have to configure a
default route in your router pointing towards the IP address of the DSL
modem.

| Is this for home use? Of course one can connect a DSL line to a 2501
leaving one with 2 serial ports for the remainder of your network
connections. If this is what your network needs then go for it. Most
home users require a 2514 or some other dual ethernet router. Judging
from the headers you are using Verizon DSL service in which case you
will never be able to send packets to your DSL modem and have them
returned. This "modem" simply acts as a bridge. Further questions
should probably be posted to 0.verizon.adsl

Nope, a 2501 won't do it for you, since it only has one Ethernet port. A
2514 would work nicely, though. You'd have to connect one of the router's
Ethernet ports to the DSL modem, the other port to your hub/switch, then
set the IP addresses for both interfaces (or configure it to get the
outside IP dynamically), turn on IP routing and configure NAT.

| In this scenario, is it possible to use a 2501, a hub/switch, and then
configure sub-interfaces to handle the internal and external connections?

| Hey Bing, why wouldn't it work even if the dsl modem acted as a bridge?
And Steve, you may have issues regarding the your ethernet int. ip address as dsl assigns dynamic ip's. | |

No subinterfaces are possible on the 2500 series. But you can do NAT-
ON-A-stick. Search for examples on CCO. It's also in the
comp.dcom.sys.cisco's FAQ.
