I followed the guide here to load the config on my Asus RT-AC66U running Asuswrt-Merlin 380.66_4 : https://airvpn.org/asuswrt/   The guide is slightly different from the current version of Merlin but I think i was able to manage. However when I went to upload the file it hung for over 10 min. I restarted the router, regenerated a config and retried and it wen though this time. Does this configuration look correct? It connects but I am still having issues with port forwarding.
