Has anyone ever ran a IPsec tunnel then drilled through with a PPTP, L2TP or SSTP tunnel? I know its not ideal and overhead would nasty but I am having issues with a CCR1009-7G-1C-1S+ and Sonicwall IPsec IKE tunnel. It works fine from the locally attached devices in the Mikrotik side (green lines) but road warrior and other remote users calling in cannot access the devices in the tunnel (red lines). We have 3 Fortinet IPsec tunnels that have no issue passing the traffic as long as you are on the VPN server behind the Mikrotik. NAT traversal has been tried off and on. Verified ports are PATed on bridge
I could visualize the Sonicwall tunnel allowing the Miktorik LAN IP to tunnel through, then we create a PPTP tunnel in the Mikrotik to tunnel through the tunnel. I've done this with SSTP tunnels running PPTP tunnels inside them. Not sure if this would work..... so the question is; is it possible?
