Lt2p as LNS and Proxy Auth

RouterOS Beginner Basics

Hi.
Does proxy auth works in LNS mode?
I see in WireShark all ProxyAuth attributes is sent to Mikrotik, but authorization starts only in additional ppp lcp phase.

What is analog of Cisco command ‘no lcp renegotiation always’ in mikrotik?

Yes, it’s possible since 6.35.4 (may be early)
