IPSec VPN behind NAT

RouterOS General
1

Hi,

I have now spend several hours trying to setup a IPsec VPN connection from a RB1100AHx2 to a RB951G. The RB951 is behind another firewall, that should NAT everything to the RB951 (I haven’t got the power over the NAT’ing firewall).

In the RB951G router there is connections in remote peers, but there is no registrations in Installed SA’s

In the RB1100AHx2 router there is also connections in remote peers. In the installed SA’s there is registrations, but Auth. Algorithm=None and Encr. Algorithm=None

I have attached a picture from the IPsec settings in the two routers.
The left part of the picture, is the RB951G
The right part of the picture is the RB1100AHx2

In the logging in the RB951 it says Couldn’t find configuration..!

Anyone got an idea what is wrong in the configuration?

this is what I use to connect from windows 8 clients.

The problem is that I have several VPN connections in the RB1100AHx2 and if I use addresses like 0.0.0.0/0 I guess it will have influence on all the other VPN connections..!

I do not dare to test in our production environment, at least in the RB1100AHx2 :wink:
