    Hi @neilos2015  

    The traffic transmitting between 2 USG VPN tunnel are worked by routing table.

    It may effects by routing/ policy control rules.

    So you can check:

    (1)   Does new IP address is conflicted in your USGs ?

    (2)   Does VPN traffic is blocked by policy control rules?

    (3)   Go to Maintenance > Packet Flow Explore and check if any routing effects to your VPN tunnel.
