Route one IP through vpn

ograweb

Hi

I have a fully functionnal network with 7 pfsense connected through OpenVPN. It's working very well !

Site A : Datacenter 10.0.0.1/24
OpenVPN server
Don't roote all traffic through VPN

Site B : 10.0.50.1/24
OpenVPN client (Dynamic openvpn ip 10.0.210.X)
VPN work well to contact Server on Datacenter from Site B
Web access don't go though VPN but directly to Wan

I want to route 1 flow (an UDP voip stream from an IPBX on site B (10.0.50.8)) to go outsite network by routing across OpenVPN (Exit flow by Datacenter Wan IP)

I try some setting :

(on Site B) Creating OPT1 interface with ovpn1
(on Site B) Creating Gateway on interface OPT1
(on Site B) Creating a firewall rule on LAN, to use OPT1 Gateway
(On Datacenter) Creating a firewall rule to (temporary) accept all flow from OpenVPN

But i's not working. I can see the data leaving Site B and enter on Datacenter pfsene, but nothing more.

What must I do ? (I think I miss a setting on site DATACENTER, maybe something with NAT (I see automatic NAT setting allowing data from Datacenter or Openvpn to exit pfsense , but no rules with Site network

Thanks

I don't do anything more, just sleep a long night and it's working ! Amazing !

Yesterday, my test don't work because i must drop existing tcp/udp flow before testing
