827 with Verizon DSL

[farslayer9]

I've been fairly unsuccessful getting my 827 router connected to Verizon DSL. Here is my configuration (this forum had a few configs that seemed to be working), and any help is greatly appreciated. My DSL modem is a Westel and it is set to bridge, so my 827 must utilize NAT. I have confirmed my username/password as well and am currently using a crappy Linksys router.

Thanks!!!

If you have a modem, you don't need a dialer config. In fact, you don't need the modem. Just the 827. I will post a complete config in a while...

Hi, I'm a moron, I meant to say that the modem is going to be chucked, I want the 827 to serve as the modem AND the router. Sorry about the confusion.

ntp clock-period 17180367

You need to tell the router how to authenticate the circuit with pap/chap callin. The ntp config is on the house...

Also, MTU for adsl is 1492, not the default 1500. The ip tcp adjust-mss 1452 is tcp max segment size, and that = 1492 MTU.

One more thing---take out the bridge stuff...I would.

Ok, here's my new config, which I've not yet tried (I'll try it in a second and post the results of a show int if it fails). I was unable to set the NTP server (unrecognized command) and adjust-mss on the Dialer1 interface was also not an option under ip tcp or anywhere else, so I just set the MTU on the dialer1 interface to 1492. Also, I set an encapsulation type of aal5snap on the ATM0.1 interface, which I saw may be necessary. If this doesn't work, is there a way to log where the connection fails?

Thanks!

Take the aal5snap encaps off, and try again. This time, do this...

router#conf t
router(config)#int atm0
router(config-if)#shut
router(config-if)#exit
router(config)#int di1
router(config-if)#shut
router(config-if)#exit
router(config)#do deb ppp neg
router(config)#do deb ppp authe
router(config)#int atm0
router(config-if)#no shut
router(config-if)#exit
router(config)#int di1
router(config-if)#no shut
router(config-if)#end
router#

You should see if the interface goes up, then down, look in the results of "debug ppp neg" and "debug ppp authe"---if you see something like "no entry for blablabla", then the username/password is/are wrong...post the results if you're not sure.

Ok, i've enabled debugging, but I have no idea how to actually display the results. Sorry i'm such a noob at Cisco.

 

[burtsbees]

Actually, you may be able to post a "sh log"...

What are you using to console? Hyperterminal? If so, Go to the top in HyperTerminal where it says transfer, and select "capture text". I think it then lets you choose a file, then you "start". But before you do, shut down the interfaces and input the debug commands. Then do the capture text and start, then turn the interfaces back up. Then copy and paste into here from that .txt file. I would recommend using Tera Term or PuTTy...
