미크로틱 vpn 설정으로 고생하시는 분께 약간이라도 도움이 되었으면 좋겠습니다.

1)    Enable L2TP Server
/interface l2tp-server server set authentication=mschap2 enabled=yes

2)    Configure PPP profile
/ppp profile add change-tcp-mss=yes local-address=192.168.17.1 name=ipsec+L2TP remote-address=ipsec-pool use-encryption=yes
/ip pool add name=ipsec-pool range=192.168.17.2-192.168.17.254

3)    Creat PPP Secret
/ppp secret add name=newvpn password=vpnpass profile=ipsec+L2TP service=l2tp

4)    Add static PPP interface to manage firewall easily
/interface l2tp-server add name=L_newvpn user=yourid

- Additional Configuration  
/ip ipsec policy group add name=ipsec+L2TP
/ip ipsec proposal set [find default=yes] enc-algorithms=aes-256-cbc,aes-128-cbc,3des
