Hello , I have some questions according l2tp implementation on TNT. I use version TAOS 9.0.0. How TNT LAC tunnels MP sessions , if I use multistack configuration ? Will bundle owner combine links and then tunnel to LNS, or every unit in stack will tunnel every session separately to LNS ? How can I control LCP negotiation in case of l2tp implementation , if I would like to avoid preauthentication? The goal is to exclude LAC from LCP negotiation as much as possible and push client and LNS negotiate within LCP directly ( or to avoid LCP proxiing might be ??? ) . Is it possible to configure authentication protocol different from which I have in answer-defaults/ppp-answer for certain client recognizable by DNIS on LAC ? Incopatibility in auth protocols on LAC in LNS causes LCP renegotiation in my case. Thanks in advance. Leonid
