Successfully got my SFH running on Proxmox thanks to this post
Added a second NIC for the SFH LAN side connection. However, when the HUB LAN is connected to my upstream router at my core and a SF tunnel with L2 bridge is created from HUB to remote, I am unable to access VLANs from the HUB on the remote side.
Design:
IPs: 10.10.X.1/24
X=VLAN ID
CORE (VLAN 60,61,62,63)-> SHF LAN-> SHF WAN> SF Tunnel w/ L2 Bridging-> MAX PRO DUO WAN-> MAX PRO DUO LAN β LAN (VLAN 60,61,62,63)
