I've set up 2 1gb nics to be bonded and bridged to a VM guest running freebsd and using the e1000 nic driver. I can successfully ping with a packet size larger then 1500 to the Host, and I can ping the Freebsd guest from itself to itself with a size larger then 1500, but I can not ping into our out of the Guest with size over 1500.
My configs follow:
I feel I should note that networking does work with the standard MTU of 1500 with these settings.
I don't have much time to putz with this thing right now so, any help to get this running is much appreciated!
My configs follow:
Code:
From Proxmox /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
auto bond0
iface bond0 inet manual
slaves eth0 eth1
bond_miimon 100
bond_mode 4
pre-up ifconfig eth0 mtu 9000
pre-up ifconfig eth1 mtu 9000
auto vmbr0
iface vmbr0 inet static
address 192.168.1.252
netmask 255.255.255.0
gateway 192.168.1.1
bridge_ports bond0
bridge_stp off
bridge_fd 0
pre-up ifconfig bond0 mtu 9000
mtu 9000
Code:
If config output from Proxmox showing it has accepted settings and "SHOULD" be working
