[skip]
I don't see 12.4.5.x for 2801 on tac, only 12.4.5 from 03 nov 2005.
I think I already have it
I'll try 12.4T ...

They are interim releases - if you believe you have one of the problems
listed ask the TAC to prvide you with the download permisssions

I don't think that I have one of these problems.
DDNS doesn't work at all , even no debug messages.
Anyway, as I understood, DDNS is not stable yet in latest IOS.
So waiting for new releases

Thank you!
