Network Routing Issue

[garyhook]

Ok, I have a network routing problem that i can't quite solve. Here's a quick summary:

Proxmox 1 (P1)
1. 4 - 1 Gig ports - all connected to a 1 Gig Switch
2. 1 - 2 Gig 10gbe ports (Linux Bridges VMBR101[192.168.100.1) and VMBR102 [192.168.100.2)

Proxmox 2 (P2)
1. 4 - 1 Gig ports - all connected to a 1 Gig Switch
2. 1 - 2 Gig 10gbe ports (Linux Bridges VMBR101[192.168.100.4) and VMBR102 [192.168.100.5)

On this host I have a test version of FreeNAS with the VMBR101 attached - it's IP is 192.168.100.3

Proxmox 3 (P3)
1. 4 - 1 Gig ports - all connected to a 1 Gig Switch
2. 1 - 2 Gig 10gbe ports (Linux Bridges VMBR101[192.168.100.6) and VMBR107 [192.168.100.2)


Since I don't have a 10gbe switch I've cabled them as follow:

A cable from Proxmox 1 192.168.100.1 --> 192.168.100.4 - Proxmox 2
a cable from Proxmox 2 192.168.100.5 --> 192.168.100.6 - Proxmox 3


Now, in a shell on each Proxmox i can ping P1 to P2 and P2 to P1.....and ping P2 to P3 and P3 to P2.

What i can't do is Ping from the FreeNAS VM to P1 or P3. I can Ping both ips of P2. Also, i can't ping P1 to P3 through P2.

So i figured i needed to add some routes in each routing table. Something like:
P1 --> route add - host 192.168.100.6 gw 192.168.100.4
P3 --> route add - host 192.168.100.1 gw 192.168.100.4

But it's not working! Any help would be appreciated!

Hi,

Have you enable IP forwarding?

 

[garyhook]

yes, i've enabled IP forwarding on all interfaces on all servers. Still having issues that I can't figure out.

After a clean shutdown and restart of all machines I can now ping from P3 to the VM running on P2 and vice versa.

However, i'm not able to ping from P1 to the VM running on P2. I'm able to ping P1 to P2 but something is not forwarding properly?

also, i'm still not able to ping P1 to P3? I've played around with adding different routes but still no success!!

any help would be appreciated!
