[SOLVED] Cant access Promox WebGui while on VPN

[killmasta93]

Hi, I was wondering if someone else has had this issue? As recently installed pfSense working and using a site to site OpenVPN, I can ping proxmox just cant access the Webgui nor SSH, i tried turning off the firewall on proxmox and nothing, not sure what to look for?
So my LAN on Site 1 is 192.168.3.0/24, where i have my pfSense hosting the OpenVPN server and on Site 2 is pfSense with LAN 192.168.6.0/24 with client OpenVPN, Proxmox IP 192.168.6.253 both sites can ping each other see pictures,

Thank you

EDIT: big importance on pfSense need to disable checksum offload on hardware for it t work
