OpenVPN Routing

[fabbotti]

Hi, I'm new pfsense' s user.
I have a problem with vpn openvpn site to site (both pki or Shared key):

i've to use vpn for alcatel voip phone, but alcatel server goes in error because phone try to auth to server with tunnell address 10.121.121.2.
Pfsense seems to masquerade client ip to tun ip address.

This is my config schema:

LAN(192.168.21510/24)–->pfsense()-->ROUTER 3G----------------INTERNET------------------Pfsense( PUBLIC IP)------LAN(192.168.2.0)

VPN works good for all service a part voip phone

Thanks
