VPN 378.53_0 RT-AC3200 - Once configured router bootlooping

Hi,

I was using the same configuration on my previous router, RT-AC87U, and all was working.
But since I got this RT-AC3200, from the first FW, as soon I configured everything it keep booting and I cannot do anything with it... Need to reset and use restoration software to reconfigure everything.

What can I do to find the problem? Is it related to the RT_AC3200?

Basically the configuration I do is:
VPN
General:
admin
user1 pwd1
user2 pwd2

Advanced settings:
TAP
UDP
1194
Auto firewall
TLS
Username/password Authentication YES
Username/password Auth. Only NO
Allocate from DHCP NO
192.168.100.10 - 192.168.100.19
Direct clients to redirect internet traffic NO
Respond to DNS YES
Advertise DNS to client YES
encryption cipher EAS-256-CBC
Compression Enabled
Manage Client-Specific Options NO

after that I Apply and that is it... need to reset everything again!

Thanks for any advice!

The RT-AC3200 is starved on nvram. Make sure you're not filling all of it by adding your key/certs.

Hmm that might be the case then! Because before adding anything related to VPN here is what I got as NVRAM Usage:
60406 / 65536 bytes

And just the key/certs alone are over 6000 bytes... I'm screwed!

I remember having the same issue once with my previous router using DD-WRT or Tomato-Shibby on a RT-N16, and I had to trick it so I could locate the key/certs into files on a partition!

Can I do some sort of files on the JFFS partition and point the configuration into the files for the key/certs, etc?

Another question, why with the RT-AC3200 the nvram is starved like this? It was not on the RT-AC87u!

The parameters/settings needed to support the third radio on the AC3200

Asus are aware of the problem. We'll have to wait and see if they do anything about it.
