1. Setup VPN server on R600VPN. If you need to access your server in different places, you can set up client to LAN L2TP VPN.

If your VPN clients are not in the fixed place, you can set up remote gateway as 0.0.0.0/0, it means that everyone can try to connect the VPN. 

2. R600VPN is behind DRG488, so you need to setup port forwarding on DRG488. You need to open port for UDP 1701, 500, 4500, otherwise VPN clients cannot access R600VPN.

So far the error im recieiving is this :

2019-09-30 19:12:57    IPsec    WARNING    WAN1: Phase 1 of IKE negotiation failed. (Peers=192.168.1.64<->xxx.xxx.xxx.xx, Error=14)

@dorksville 

It seems that your router is behind other router. You need to open UDP port for your VPN router. Make sure that your front router support to open port then configure it.

Hiya Anyone I do apologize I should of updated this post. This has been resolved now. It was a slight error of my own.

Thankyou for replying though. 

@dorksville Hi Getting an error 14, do you remember what your issue was as I can't find the meaning of error 14?

I encountered Error 14 too, and was looking for reasons.

In the end, it was my mistake so i will share my solution. It may not be the only solution. My Responder was an ER6120 and was showing error 14 in phase 1. However, i had selected the wrong interface for the VPN in the WAN interface setting. I had selected an inactive interface. It still showed in the logs with no specific error but after i selected the correct incoming WAN interface on the responder, the tunnel came up.
