I have a router running Vyatta. It doesn't have a T1 card, and they are too expensive. I was looking on ebay and see Cisco 1721 routers.
I'm wondering if I can terminate a T1 into the 1721 and then connect into the Vyatta router. However, I want to be able to control everything from the Vyatta. So basically make the Cisco pass all traffic...
Can anyone explain if this is possible, and how complicated/sloppy it will make things?
