mariofiorentino

Hi all,

i have two Openvpn Server

one is Site to Site Vpn
two Roadwarriors Vpn Connection

I would like to connect to site to site vpn from roadwarriors vpn

Could you help me ?

That's just a routing issue - you have to ensure that all devices (or at least their default gateways, the routers) know how to reach all the IP ranges you're using.

That's easier if your OpenVPN servers are also the default gateways for their networks. If they aren't then ensure that all the default gateways, on both the local and remote networks, know how to route to your Roadwarrior IP range. You'll also want to ensure that the Roadwarriors have the OpenVPN server pushed as their default gateway or have appropriate static routes pushed.

For anything more precise you'll need to provide a diagram of your networks, how they are connected and what IP ranges you're using.

you will also want to remove your actual public IPs/FQDNs from your examples above.

On one pfSense box I have the following OpenVPN configurations:

As a server for Road Warriors
Dynamic IP: yes
Address pool: 10.99.254.0/24
Local network: 192.168.100.0/24
Client-to-client VPN: yes
Cryptography: BF-CBC (128-bit)
Authentication method: PKI
CA cert
Server cert
Server key
DH parameters
TLS
LZO compression: yes

As server for Site-To-Site OpenVPN
Address pool: 10.11.12.0/24
Remote network: 192.168.200.0/24
Cryptography: BF-CBC (128-bit)
Authentication method: Shared key
Shared key cert
LZO compression: yes

My routing issue is:
From Site 1 I can reach hosts on Site 2 and vice versa.
From Road Warrior I can reach hosts on Site 1.
I want to be able to reach hosts in Site 2 from Road Warrior.

Could you help me ?

It would be much, much, easier to help you if you'd provide the information we ask for.

I'm guessing that Site 2 doesn't know how to route to the Road Warrior LAN.

mariofiorentino

Yes :) Roadwarriors don't ping site 2

Cry Havok

I'll say it slightly differently - have you configured the routers at Site 2 so that they know how to route to the Road Warrior subnet? They'll need a static route for 10.99.254.0/24 with a route through the Site 2 OpenVPN server's LAN IP.

I was told this arrangement isn't possible to have OpenVPN clients to one LAN have their traffic pass through another OpenVPN to another LAN… so I just setup more OpenVPN clients and servers.... it would be nice if each site could only need 1 OpenVPN...but I never got that working!

GruensFroeschli

That's not actually true.
I have this exact setup working.

It's really a matter of setting up static routes on every router involved, so every devices know where to send traffic to.

Cry Havok

It is perfectly possible - I've done it and I know some folks who have an intra-site VPN that they use daily without problems.

As GruensFroeschli said, it's just a matter of getting the routes right.

joako

I don't follow. The site to site openvpn comes up and the routes are setup. I have a client-to-site VPN on the same pfsense and I ass the correct push route statement to the openvpn configuration.

Client VPN traffic goes from openvpn to pfsense first hop, but then no further.

How could I add a route for this?

GruensFroeschli

The other side of the site-to-site knows nothing about the roadwarrior subnet.
–>you need a static route to make the roadwarriors known.
