Hi Guys,
I’m trying to setup L2TP Server with IPsec encryption but with no expected results. I’m using two network devices:
- Ubiquiti Nanobeam M5 (connection to the ISP, router mode)
- Mikrotik RB2011UiAS-2HnD-IN (VPN server)
The problem is I can’t switch Nanobeam mode to the bridge because of the ISP requirements (they don’t allow to use device in bridge mode). On Nanobeam device the NAT protocol is enabled. So I think, the problem is here (L2TP server behind NAT).
I have tried to disable NAT on the Nanobeam device and add static route to the Mikrotik (network 192.168.88.0/24, gateway 10.0.0.2/8) but it doesn’t work.
Nanobram configuration:
- Firewall disabled
- NAT enabled
- DMZ to 10.0.0.2
The L2TP client says that VPN server is not responding (but all incomming connections are ok).
Is any possible way to configure L2TP Server correctly?
