Hello
I run a PPTP VPN server on Mikrotik “A” with a public IP. The PPTP interface is doing a NAT masquerade.
I connect a remote Mikrotik “B” with a PPTP client on the server “A”. “B” receives the VPN IP : 10.10.10.100. The PPTP interface of “B” is also doing a NAT masquerade.
On the same LAN of Mikrotik “B”, there is a device “C” 10.10.10.200 for which Mikrotik “B” routes all the traffic via the VPN. (Mangle mark-routing and route via VPN)
The device “C” can access the internet correctly but however its traffic is going through a double NAT on “B” and “A”.
How can I avoid this double NAT ? Isn’t there an easier way for Mikrotik “B” to tunnel 10.10.10.100 with 10.10.10.200 instead of using a second NAT masquerade ?
