I've setup Proxmox on Debian Desktop environment.

Working:
  • DE connects to wifi (travel router or any other wifi) and can function as a DE.
  • Wifi connection is forwarded to PVE (ipv4 forwarding, dnsmaque enabled).
  • I can reach guests from the laptop/host.
Not working:
  • Clients connected to the travel router cannot access the guest machines.
Config:
  • dnsmaque - dhcp for proxmox guests 192.168.100.50 - 192.168.100.199
  • vmbr0 IP 192.168.100.1 (no gateway assigned)
  • travel router subnet 192.168.64.0/24
Issue:
  • unable to get guests talking with clients on travel router.
What I've tried:
  • setting vmbr1 to 192.168.64.x
    • pve/host cannot access router admin
    • clients on travel router cannot access guest machines
    • clients on travel router can still access router admin
  • Changing the travel router to 192.168.100.0 subnet and keeping dhcp above that what is set in PVE
    • same issue as above
    • breaks internet for host/pve
I do have OPNsense virtual machine available if this would help with this scenario.

Is what I want to do achievable? or am I chasing a losing battle?
If I have missed out any useful data/info please let me know

Thanks
