Use site to site VPN between organisation with also client VPN active

[NaorElkayam]

Hi,

I have the following installation:

Organization 1: MX450 as VPN concentrator

Organization 2: Z3 as a teleworker that also running client VPN

I need the Z3 to open a site to site VPN (which must be manual since they are not on the same organization) and also have clients connecting to it using l2tp client VPN.

The problem is that both use port 4500...

This photo describes the installation

Thanks!

The client VPN pool has to have the "include in VPN" option set, and the remote party has to have it included in their VPN encryption domain you you

You also need to forward udp/500.
