OpenVPN Outbound NAT

I just upgraded to 23.7 and migrated my OpenVPN remote access server to the new instance config. I am not completely certain, but I thought "OpenVPN networks" was listed under Outbound NAT automatic rules. Was removing it something intentional or a bug? I created a manual outbound NAT rule which got me going, but I want to mention it here just in case.

Same here, I think this is a bug.

Version   23.7.1_3

The NAT rule is important when, for example, the default GW is redirected. Without NAT no internet access is possible

NAT rules are manual now with IPsec/OpenVPN MVC pages.

Good morning,
how does this outgoing NAT rule have to look like?
I'm having problems with my OPN servers: Both the old server configuration and a new instance do not connect.
Thank you

The NAT rule is only for connecting OpenVPN users to the Internet. Access to internal resources would not go through the NAT.

Here is how I have it set under Firewall > NAT > Outbound:

1. Set the Mode to "Hybrid outbound NAT rule generation"
2. Create a Manual rule and set the following options:
  • Interface = WAN
  • TCP/IP Version = IPv4
  • Protocol = any
  • Source address = OpenVPN net
  • Translation / target = Interface address
  • (optional) Log = checked

Thank you!
