Hi we have a router which acts as an LNS and authenticates LT2P sessions via radius assigning each to a tunnel interface and giving it an IP address, we would also like to assign DNS settings via radius, we are using steel belted radius which is capable of doing this but we can't seem to get it to work.
What I believe are relevant sections of the config are below;
Any help greatly appreciated.
Thanks
Matt
