OPNSENSE and PROXMOX home networking

[tinashechipomho]

I have been working on this for days and I got stuck its time to ask you guys to help, my setup is pretty simple, i have attached the diagram and what i am able to do.

On my laptop (E)

I can ping and access the following:

D 192.168.50.1 (wireless router)
C 10.1.5.2 (managed switch)
F 10.1.5.[11-13] the nodes in the proxmox cluster.
B 10.1.5.1 access the opnsense box on both LAN and WAN ip address (LAN-10.1.5.1 and WAN-10.1.1.10).
A 10.1.1.1 isp router.

essentially i am able to access every device. I can even login to the proxmox nodes via the browser or ssh.

I have two problems on my opnsense and proxmox cluster.

FIRST PROBLEM OPNSENSE:

if i login to opnsense box, I am not able to ping any proxmox node) i get the following error:

Enter a host name or IP address: 10.1.5.11
ping: sendto: Invalid argument
ping: sendto: Invalid argument
ping: sendto: Invalid argument

I am not able to ping the switch:

Enter a host name or IP address: 10.1.5.2
ping: sendto: Invalid argument
ping: sendto: Invalid argument

I can ping the wireless router. 10.1.5.10
I can ping the ISP router 10.1.1.1
I can ping any IP on the internet.


SECOND PROBLEM 3-NODE PROXMOX CLUSTER.

Each node has 4 physical NICS nic1 assigned an ip from lan 11,12,13

NIC2 & 3 reserved for VM to be created on the cluster
NIC4 assigned IP addresses: 10.1.6.11-13 for cluster management (to be used for CEPH storage and any other management)

If i login to the proxmox nodes, the nodes can ping themselves.

I can't ping the ISP router 10.1.1.1
I can't ping the opnsense 10.1.5.1 (configured as gateway)
I cant ping any ip on the internet (i have no internet connection)

I can ping the wireless Router (10.1.1.10)
I can ping the managed switch (10.1.5.2)



What have I missed? Please help?
