hi :)

i've just bought an usg60 and connect site-to-site with a RRAS on windows server 2016.
phase 1 AES128/SHA1 DH2, phase 2 AES128/SHA1 PFS none 28800 lifetime for both.

the tunnel is stable and works fine (10MB/s U/D between local network and the windows server RRAS resources) but during transfer a file (100MB circa) tunnel drops for few seconds than restart.

Why?

Thanks in advance,

    Hi @zumopotato  

    On USG60 the VPN tunnel will disconnect when it is reached SA life time.

    But it will reconnect automatically if enabled nail-up function.

     

    Can you take a screen shot in Monitor > Log during VPN tunnel disconnect and re-connect? 

    It may show what the reason leads VPN tunnel disconnection.
