No Internet on WAN interface

[utp_ss]

Please tell me, for the first time starded with a dedicated server.
There is an allocated server on it ESXI, a static white IP 37.XX.XX.XX/26 is spelled out on the network adapter.
I installed PFSENSE on a virtual machine and there was a difficulty in configuring a virtual network that looks into the Internet.
If I assign her the same IP as it was issued to my server, then access to the ESXI web Mord (it is at 80 port) disappears.

Compared on the Internet with similar situations, though the IP server received there via DHCP (here it turns out that the same
settings on the physical network map of the server and on the virtual map of PFSENSE, looking on the Internet)
