Need OpenVPN on a pfSense behind NAT Router

[sianand]

Hi all,

I need a help in configuring OpenVPN in pfsense behind a NAT device.

The network is as below.

ISP ---- Load Balance Router ----- pfSense (HA) ---- LAN

WAN IP of pfSense is in 10.10.10.0/28 range and in HA.
I also have port forwarded UDP 1194 in router to WAN VIP of pfSense.

But, I'm unable to connect via OpenVPN.

Please help

Thanks,
Sakthi

Make sure you have unchecked Block private networks and loopback addresses in Interfaces > WAN

If your double NAT'd you'll have to open the OVPN port on your Load Balance Router - Just an uneducated guess.

@Rico This is done, without this pfSense didn't allow internet connectivity.

@randombits pfSense isn't doing NAT, sorry I didn't mentioned this.

That's probably a dont care.
The destination isn't NATted by pfSense, because the end destination is pfSense itself.
A

on your WAN interface will do (if you use UDP on port 1193 - this rule will be created by the OpenVPN wizard if you used that wizard).

The upstream router - if any - has to have a 'real' NAT rule of course.
