Trouble with LAN interface

[alexart]

My pfsense installation (2.1.5-RELEASE) is on a virtual machine (proxmox) with two dedicated ethernet interfaces (one for WAN and one for LAN).
Now I've one ip for LAN (192.168.1.7) I'd like to add a virtual IP to LAN interface (10.80.0.1).
I've added the virtual ip (with 10.80.0.1) and configured all access rules to it but from my network pc (with dual ip configuration: 192.168.1.37 and 10.80.0.10) I can't ping the virtual ip.
any idea?

Thanks
