I just upgraded from 220.127.116.11-q50 to 18.104.22.168 and started with a fresh configuration. I was able to connect to the RV042 as per normal, with the Greenbow VPN Client. I checked off NAT-T in my tunnel config, and did not specifcy a Local address in Greenbow, which are the only things I believe I've done differently. The tunnel connects, it's just that I can't connect to, or ping anything on the remote side. I do have the proper subnet configured in the tunnel config.
