0x890d is Fast Roaming Remote Request (https://tools.ietf.org/html/rfc5342) Its not a crash but a dump of packet causing translation problem.

It's not a crash but in some cases the NAT stops working until I manually reboot the device, like for the issue "tsl free list empty"

4

Yeah we are investigating that. I believe that happen only with IPSEC/PPTP VPN?

5

I think that this issue (NAT Translation attempted for non IPV4 packet) it hasn't been caused by VPN traffic

6

Yeah but TSL free list empty log comes when VPN is used.
