FW blocking some connection / double bandwitdh in graphs

thelive1

Hi All,

First post here and new to pfsense, so apologies in advance if this isnt posted where it should be..
I installed pfsense on a vm in our network, because we've been having bandwidth issues and i would like to monitor who is sucking up all the bandwidth.

However i have two issues:
1. bandwidth is counted double in the stats (least urgent)
2. some connections are blocked even tho there is a allow any to any rule on both LAN and WAN

Topology:

Multiple sites connected through MPLS/VPN

Site A:

i cant put the FW between the router and the core switch for reasons, so i just created the VM with 2 NICs.

WAN (192.168.162.53) and pointed GW to original GW .254
LAN (192.168.162.54)
Pointed GW for the DHCP ( running windows server ) to .54
2 Rules: Any to Any on wan | any to any on lan

Site B:
My main location, original setup, no pfsense deployed (yet)
Sadly, IP range is 192.0.0.0/24

Symptoms:

a)

RDP/PING to PC/Server with DHCP lease on site A from Site B does not work
RDP/PING from these devices to my PC on site B = OK
Devices who use original GW have no issue

b)

user goes to sharepoint, the server is located on a 3rd site ( 172.28.2xx.xx) , they get login prompt for their AD user, keeps looping for login )
devices who use the original GW, have no issue

c) not as urgent
Double traffic on interface, both ip .53 ( WAN ) is show in LAN traffic

FW logs show a lot of this:

and some of this

Rules:

and

Disabling the FW fixes the issues but i'd like to do some limiting etc, so this isnt really an option..

Is my FW setup fundamentally wrong? whats up?
