L2TP VPN Problem (RV340)

Hi Guys.

 

I configured the L2TP VPN as below using the RV340 Router.

l2tp.GIF

IPSec Profile is as follows.
  1.Default (IKEv1)
      Phase I Options: Group 5, AES-128, SHA1
      Phase II Options: ESP, AES-128, SHA1, Group5

 

The log found in RV40 is as follows.

Re: L2TP VPN Problem (RV340)

I am getting an error in the Android VPN Client Program. (FortiClient app)

Isn't there any problem on the log?
