HI,
I had configured UC560 via Telephony configuration wizard in CCA and I assigned PPPoE configuration too. After saving the configuration I was able to get the internet connection from UC.But after a day I removed the Dialer0 interface cable and reconnect it again, there is no internet connection. But but in this case I checked the interface status and it is showing Dialer0 unassigned and port is Up also.That same connection I checked with Linksys broadband connection by providing Internet account username and password which I assigned inside UC and I was able to get internet connection.
Please suggest any additional configuration I have to do inside UC to get internet connectopn back.
Regards,
Rinchu Raj

Maybe you will have to use CLI, because from experience and hearsay, is not like the CCA GUI gets it right all the time.

Dear Paolo,
Let me know this conf is enough?
interface Dialer0
description $FW_OUTSIDE$
ip ddns update hostname abc.dyndns.biz
ip ddns update sdm_ddns1
ip address negotiated
ip access-group 104 in
ip mtu 1452
ip nat outside
ip inspect SDM_LOW out
ip virtual-reassembly in
encapsulation ppp
dialer pool 1
dialer-group 1
ppp authentication chap pap callin
ppp chap hostname
ppp chap password 7 <09545611011D0F4359>
ppp pap sent-username
ppp ipcp dns request
And any thing more I need to do with access list?

I would recommend
interface Dialer0
default ip mtu
mtu 1492
no ip access-group 104 in
no ip inspect SDM_LOW out
no ip virtual-reassembly
ppp ipcp route deafult
Then you can check with "debug ppp neg" and "term mon" how it goes.

Hi Rinchu,
I would plug the cable back into the WAN port and then log into the CLI and do a "shut" and then "no shut" on the dialer0 interface.
Your configuration is fine and is a standard setup, not sure why though it is coming up as unassigned.
As a last resort though, you may need to give the UC a reboot and see if that brings up all the interfaces properly, such as any virtual ones as well (Although you shouldn't have too).
Cheers,
David Trad.

Yes It is working .......I done the configuration via CLI and put the access list 104 I edited the access list to permit all to all. now UC is sharing internet.I tested by shutdown the UC and restarted it is working fine.

You would have better performances with "no ip mtu 1452".
The access-list is not need because you have NAT, so your itnernal LAN is inaccessible anyway,
And I recommend to remove virtual-reassmbly because I've seen it failing so often.
