IPSec VPN site-to-site pfSense + Cisco ISA500
-
Hello guys, I am using this awesome pfSense since 1 week and I couldn't be happier with it :)
Actually I have it running on a remote Datacenter and has 1 public fix IP for the WAN and one LAN ( 192.168.1.0 /24 ) with IP 192.168.1.1 ( acts as default gateway for the server )
I have also a Windows Server 2012 running and uses the pfSense as gateway and works perfectly, i can browse the internet etc etc.
So the scenario is:
pFsense
WAN: 144.x.x.x
LAN: 192.168.1.0 /24Cisco ISA500:
WAN: 46.x.x.x
LAN: 192.168.20.0 /24I need to setup IPSec VPN site to site because will use this server as our DC server from our office, so we need a secured connection.
I have done all the necessary steps on the pFSense to setup the IPSec VPN.
When it comes to the Cisco ISA500 I do all the steps but when I define the local network and remote network and I press OK it says:
A policy already exists for this Local Network and Remote Network.Does anyone know why this happens ?
Thanks to all!!!

Hello to all, we have fixed the problem. It was due to another VPN active with same subnets. We changed networks and all is working perfectly now!
