Multi Site VPN and routing to each site without CSO

[samnet]

Dear All
Im struggling to make the proper Multisite VPN to interconnect between all sites.
I recall doing it few years back but cant replicate this in the new opnsense edition. not sure if this is version restriction or something related.
I have:

Site A (Openvpn Server) Ip 192.168.11.0/24 / OVPN Tunnel IP 10.10.11.0/30 (note Ive selected /30 not /24)

Site B (Openvpn Client) Ip 192.168.22.0/24 / OVPN Tunnel IP 10.10.22.0/30 (note Ive selected /30 not /24)

Site C (Openvpn Client) Ip 192.168.33.0/24 / OVPN Tunnel IP 10.10.22.0/30 (note Ive selected /30 not /24)

Site B and C can ping and connect to Site A and vice versa.

but I cant get site B and C to communicate (even through Site A and yes Im fine with single point of failure on site A) I just want it to work.
I recall doing this in the past editions by adding the subnet in the "IPv4 Remote Network" of each client. but this didnt work I tried adding even on the server remote network. can someone clarify how this can be done?

Hi Samnet,

you need to assign an interface to ovpn client B and C, and then set static routes accordingly.
Also, you need to correct your tunnels configuration.
You have configured a S2S as a multi client network.

I.E.

Site B 192.168.33.0/24 GW 10.10.22.2 (Ovpn GW Site A)
Site C 192.168.22.0/24 GW 10.10.23.2 (Ovpn GW Site A)

And check the rules on OVPN tab

Did really get you on this
Do I need to do static route?
8 have managed to get it working by inserting remote network on each site
Would this be ok?
Also what gateway do mean?

Why not using CSO? It works flawless with CSOs
