Hi Guys,

I'm encountering a strange issue with an L2TP VPN Client To Lan configuration

Clients are OSX 10.7.5 (Client bundled with the OS)
It works fine at first but after a day or two, it stops accepting new connections even if the number of maximum connections hasn't been reached (checked in List of Tunnel)
OSX client state that Server is not responding

Config is like that
IPSec enabled
VPN-to-Internet is enabled
Hello Interval 60
Protocol: L2TP
Mode: Server
Tunnel: Client To LAN
Max Connections:10
Encryption enabled
Client IP 0.0.0.0
IP Pool 192.168.100.1-192.168.100.10 (network here is 192.168.1.x)
No remote subnet

Does this ring a bell or is this a firmware issue ? Currently using 1.0.7 which is the latest one AFAIK.

Thanks,

Maybe there's an attack in your network.

You mean like lots of connections try on the VPN ?
The log do not display such thing.

Or something going on inside the LAN ?

Thanks,
