Running 384.11_2 on a RT-AC66U_B1. I have a client on my network attempting to connect to a IPSec VPN through the router. After a fresh router boot, the client us unable to connect to the VPN. Doing a packet capture on the client, I see an initial ISAKMP packet to destined to the VPN IP with no response, and then a period retry of that initial ISAKMP packet. If I go into the router to the "WAN - NAT Passthrough" page and cahnge/apply ANY of the settings, the client is then able to connect to the VPN. Even if I then revert the "WAN - NAT Passthrough" settings back, the client is still able to connect. If the router is rebooted, the issue returns.
I want to be absolutely clear, the actual value of the settings on the "WAN - NAT Passthrough" page have no impact on whether the client can connect to the VPN or not, it's just simply that a setting on that page must be changed/applied to fix the problem temporarily until the next router reboot.
Any additional data I can collect & provide to help figure out the issue here?
