I am total network noobs so please bare with me. I would like for Proxmox Host to be able to access Unraid share which is behind virtulized OPNsense firewall on Proxmox
Promox is set up on appliance with multiple physical NIC, but for simplicity let's assume it only has 3 NIC.
1/ One is currently use as management access for Proxmox host, which is connected to a ISP router (192.168.0.1, which runs DHCP and local DNS). I can't put ISP router into bridge mode, and I am still using it for some up stream devices (IoT) and for internet access redudancy (in case OPNsense is down). Its subnet is 192.168.0.0/24. It is connected to vmbr0 (physical NIC: enp1s0). IP is 192.168.0.251
2/ WAN port for OPNsense (vmbr1, enp2s1), which is connected to ISP router. IP is 192.168.0.13
3/ LAN port for OPNsense (vmbr2, enp2s0), subnet is 192.168.1.0/24. OPNsense' IP is 192.168.1.1. My Unraid is on the same network, IP is 192.168.1.100
My understanding that because ISP router is not aware of OPNsense subnet, it can't route any request to 192.168.1.100 from my Proxmox host. I think the solution is to add a static route but after googling for a while I still do not understand how to do it. Is there a way to do it via GUI? I am okay to do some command lines.
I think another way is to move my management access to LAN but if the OPNsense is down I will loose access to Promox, right? or can i also move my management access to WAN network (vmbr1) without such downside?
Any help is appreciated
