[SOLVED] Compatible motherboard (Linux Bridge mode problem)

[Limak]

Hi every one,
I have problem with linux bridge... I have 2 PCs for tests.

1. custom old PC

• MO Gigabite Z77 DS3H rev 1.0
• CPU i5-3330
• RAM 2x8GB RAM

2. DELL Optiplex 460

• MO DH67M01 rev A00
• CPU i5-2400
• RAM 2x8GB

I am use the same RAM, Disks (2x 250GB seaget testing drives 3,5ich befor buing 2x6TB WD GOLD) and PCI LAN card tp-link 1GB/s tests on MO LAN don't gives different resoult.

On the same network interfaces confiuration

auto enpXs0

iface enpXs0 inet static

   address 10.24.49.22

   netmask 255.255.255.0

   gateway 10.24.49.1


auto vmbr0

iface vmbr0 inet static

  address 10.24.49.33

  netmask 255.255.255.0

  gateway 10.24.49.1

  bridge_ports none

  bridge_stp off

  bridge_fd 0

On PC with Gigabite MO FreeNAS (or ubuntu for try) don't have connection with router and external ping like 8.8.8.8

But on Dell freeNAS (or ubuntu for try) have internet connection.

Do you have any list of MO (best on ATX) or chipset with it works?

In addition the brctl addif vmbr0 enpXs0 gives nothing.

Few months ago i tested proxmox + freeNAS with bridge on HP eliteDesk 800 G1 and I didn't have any problem with network. In future I will want buy some RACK mountable case based on standard ATX I think.

you can't have 2 gateway, and 2 ips in same subnet 10.24.49.0/24 , if you want to be able to reach them from outside.

also, you vmbr0 have "bridge_ports none", so no communication to outside is possible.

you can simply have a simple setup, with 1 ip like

auto enpXs0
iface enpXs0 inet manual


auto vmbr0
iface vmbr0 inet static
  address 10.24.49.33
  netmask 255.255.255.0
  gateway 10.24.49.1
  bridge_ports enpXs0
  bridge_stp off
  bridge_fd 0

Thanks for your reply.

I tried it before but i don't tried change IP manually on FreeNAS in interfaces, well thanks a lot.
On second vm (ubuntu) automatically gets IP from DHCP.
