I have a customer that I have connected via RB112 with Src and Dst Nat and given his 'Hot Brick' VPN router a private address. On the other end, his 'Hot Brick' has a public IP. He has enabled IPsec and Netbios on his routers.
Much to his dismay, the VPN established just fine. However, it drops the connection whenever he tries to pull a file across the VPN. (It's not the wireless link, he's holding 4mb each way with 20ms ptp.)
The "Hot Brick" maker says you can't NAT an IPsec VPN, and that's the problem.
I believe that it's the cheap 'Hot Brick' router.
I'm new to Mikrotik, and it's my first attempt at providing NAT'd addresses to customers.
Any input is appreciated.
