VPN Router-Client doesn't work out of USA

You have not provided any information on which to base a suggestion.
Do you see the connection attempts on the WRV200?
The location from which the VPN is attempted might have VPN access restricted/blocked.
What errors if any are seen on the client?

We have access to the VPN in USA.
We are trying to access from  Ecuador and  Argentina without success.
When we ran the Quick VPN client  the systems send this message:
- Connecting
- Activating Policy
- Verifying Network,
 the program  send this error:
 The remote gateway is not responding. Do you want to wait?
Yes or No
We answer Yes

Without succes.

In the VPN Log we activity
 
"loading secrets from ëtc/ipsec.secrets"
listening for IKE messages
forgetting secrets
 

VPN log is that from the wrv200?  The client reports that it is not receiving a response.  Do you see the request on the WRV?

Yes,  the VPN Log is from the WRV200
The client received the message ""The remote gateway is not responding. Do you want to wait?"

The notice is that the client did not receive a response. and is generating the error notice.

This might be an issue with the location you are in that is not permitting VPN access.  You should check with the party through whom you connect to the net whether VPN access is being blocked.  If you use your own router, make sure that it has VPN IPSEC passthrough enabled.

What are the parameters that my ISP could block for VPN acces?

UDP Port 500/4500, 1723, 1701,10000 depending on what your VPN client uses.
Are you able to access SSL encrypted sites from these locations, setup an SSL VPN if the option exists.

The ISP doesn't block those ports

IF the ports are not being blocked, you should see at least access attempts on your side that either fail because of phase 1, phase 2, passphrase mismatch etc.  If you see no attempts, that suggest that it is being blocked/lost somewhere along the way..
If any of the packets reach your server, you should see it either an error because the packet was malformed/fragmented, etc.
