Title: VPN (mental pose)
Post by: Darkopnsense on March 22, 2020, 04:03:43 PM
Hello community,

On VPNs, there is literature that I have and that I browse.

There are also reluctances to deploy dual NAT except that it neither has a choice.
Box FAI-> Box OPNsense-> LAN
Anyway this configuration is very implemented.

My question is very simple and in two points.
Did you operate:
1) OpenVPN through double NAT?
2) WireGuard through double NAT?

Regards,

PS: If so, I come up against a firewall rule problem.
My spirit takes hold.

OK, simple answer:
1) no
2) yes

More elaborately:
I never used nor tested OpenVPN.
I'm currently running Wireguard with doubleNAT:


Internet
|
ISP-Router with VoIP-stuff
|
OPNsense
|
LAN, Wireguard, ...


Basically https://wiki.opnsense.org/manual/how-tos/wireguard-client.html without Outbound-NAT (https://wiki.opnsense.org/manual/how-tos/wireguard-client.html#step-2c-assignments-and-routing).

Hi @johnsmi,

Thank you for your quick response, you are opening a path for me with "without Outbound-NAT", perhaps this is a possible resolution to my problem.

Hello community,

The responses were not rushed. Given the number of posts on VPNs, people should not serve ...

Good information point although the deployment is not finalized. I ping my tunnel with WireGuard behind a double nat on APU machines of PC-Engines under OPNsense.

Cordially.
