problem with 2600 router

hi, i have some problem with my cisco 2621 router.

i want to configure my 2621 as a CPE PPPoE client. my device sit behing a cable modem.

when i try to connect, wan interface (ethernet) and DIALER interface are up , but i don't receive dynamically an IP address from my ISP.

i'm figuring out that the problem is ppp authentication but when i use debug ppp authentication and negociation to solve problem, i do not seen anything. debug ppp does not working.

the problem can, be my IOS since i dont see any logging for ppp debugging.

what is problem ? i muist upgrade my IOS ? thank for help

Try debug "ppp negotiation". If you don't see anything, then check "debug pppoe".

Then as mentioned above the problem can be on the PPPoE part, that yous can troubleshoot with the appropriate debug and show commands.

This happens because PPPoE was still open to the device you where using instead of the router, so it was needed to reinitialize that.
