I've a context acting as LAC for a customer and I would like to "walled
garden" (http redirect) their end-users when the customer's network fails.
Since the context only contains routes for their LNS endpoints, I will
be terminating the users locally (through aaa authentication radius,
none) and using HTTP redirect.
The problem arises when the end-user's browser initiates a DNS request,
if the customer's network is completely offline, I'll need to handle
this as well.
Can't find any reference to a DNS proxy in SEOS so my next best option
is to NAT them somehow so they can access our public DNS servers,
I wanted to do this intercontext and wanted to know the following:
1. Is NAT policy now possible on L2TP subscriber? (last I checked it was
2. Is intercontext NAT possible? (i.e to local context) despite lack of
an intercontext interface? (was planning on doing an static intercontext
3. Any alternatives to this? can't place anything else in the network
since it is dedicated.
Thanks in advance,
