Problem doesn’t go away if I shutdown and bring up interfaces. Not sure if its ADSL2+ related for us as the 827/837s that have shown this behaviour aren’t ADSL2 capable.  Virtual interface comes up ok and I can ping the outside world no problem, can connect in via VPN and incoming email works ok (as long as it doesn’t time out) and web works occasionally.

 

I have also tried with the newer adsl firmware from ftp://ftp.cisco.com/pub/access/800 with no success.
