Can anyone tell me what is the cipher combination used in Nebula, when someone wants to connect to an NSG via L2TP?

Is it 3des-sha1-modp1024 (3DES, SHA1, DH2) and 3des-sha1 (3DES, SHA1) or something else?

Just found out it is like that. I had to wait 1-2 minutes until the pass was overwritten.

    It should work fine with
    Phase 1 Algorithms: 3des-sha1-modp1024 
    Phase 2 Algorithms: 3des-sha1

    Could you uncheck PAP from the PPP settings and try again?

    Moreover, is your device behind NAT?
