No connectivity to remote site via openvpn

[jasond_AU]

Scenario:
1. Site A  <–> Site B (site-site openvpn)
There is an established site-site openvpn service which works fine between site A and site B, server running on port 1194 at Site A

2. OpenVpn Client <--> Site A (Remote access SSL/TLS + Auth)
There is a working remote access openvpn server running on port 1195 at Site A. OpenVPN client can access LAN at Site A

3. OpenVpn Client <--> Site A Site B
The same openvpn client cannot access any network resources on the LAN at Site B, via Site A.

The OpenVPN client (running windows7) has routes for LANs at site A and B.

How do I determine if this is a routeing, firewall , or vpn issue?

Packet capture.

Have you added an outbound NAT rule for the OpenVPN interface at site A? This will be necessary since the OpenVPN clients IP will be unknown at site B. So response packets will be sent over the default gateway instead of VPN.

I think that its a routing issue,

Did you put in openvpn server configuration, the address of the network of site B?
