Site to Site not routing
-
Hello,
I'm trying to do site to site with 3 sites, I would like all the sites to communicate with each other:
(192.168.15.x)10.10.11.x –------- (192.168.10.x)10.10.11.x ---------- (192.168.224.x) 10.10.11.x
Client Server ClientI have 2 issues:
-
The clients connect without a problem to the server and the pfSense client 10.10.11.x can communicate with 192.168.10.x but the subnets behind the clients can't connect to 192.168.10.x.
The pfSense server 10.10.11.x however can't communicate with any local subnets.
By looking at the traffic when issuing a ping from 192.168.224.x to 192.168.10.x, I see the ICMP packets on the openvpn interface of the client. However nothing shows up on the server tcpdump.
If I enable nat on the client so 192.168.224.x traffic is replaced by the 10.10.11.x IP, the traffic goes through. -
The 2 clients 10.10.11.x do not communicate at all with each other, from pfSense, they can't ping each other.
I attach server/client config, firewall rules on all open vpn interfaces are open to everything.
The routes are being pushed correctly, routing tables look fine.Server:

Any help would be appreciated.Thanks.

It looks like I was missing the iroute statement for the clients. So now the clients subnets can connect to the server subnet but the can't connect to each other.
192.168.224.x access 192.168.10.x but not 192.168.15.x.I must be missing another piece here.

Inter-client communication

Actually it was a misconfiguration on one of the clients, it was missing the remote subnet option. I did not need to add the client-to-client option on the server side, it looks like when selecting peer to peer it's already there by default.
Everything seems to be working now, thanks
