Two NICS question

[Kristopher]

Hello, wonderful people!

 

Question, I have two NICs on my unRAID server, configured as such:

 

eth0 - 172.16.17.252

eth1 - 172.16.17.251

 

I want to have all my docker traffic go over eth1 (.251) but all my remote shares via eth0 (.252).

I have created the bridge and I thought I had it configured correctly, but for some reason, the dockers all show .252 as the IP address.

 

 

 

Basically I thought this would be a fast way to separate the traffic so "acquisition" dockers (ahem, SAB, etc) would not run their traffic over the same NIC as the shares (where PLEX streams from).

 

 

So, I'm just wondering what I'm doing wrong. 

Would it be easier to just change the FSTAB mounts in the media server?

 

I know that unRAID is using the management interface as .252

 

 

Any words of advice? 

 

[Kristopher]

Or, is it because they're on the same subnet?

Should I create another, separate network in my router (say, 192.168.10.X/24 for example) and then assign that second NIC to that?

Basically, I guess I just don't understand how unRAID is handling the traffic. 

I didn't think having two NICs on the same subnet should be an issue - my QNAP separates its traffic fine between interfaces, all on the same subnet.

this can be done by editing the smb config and setting the interface option and ip option.
 

your smb would need 

interfaces = 172.16.17.252

For dockers I would leave unraid networking settings and default settings alone... maybe swaping mac nic for what eth# they are so eth0 and eth1 swap places.

making:
eth0 - 172.16.17.251

eth1 - 172.16.17.252

Have bridging off. May have bonding on but only for eth0

Then user script plugin and replace your smb config with this:
example smb config:

smb ip fix

FYI per your network settings info br0 is attached to eth0 only.
at the top you would need both eth0 and eth1 in the same br0.

Unraid termianl
show ip link

would help seeing the bridged interfaces.

[Kristopher]

I'm not sure why I'm changing SMB? 

I also use NFS far more than SMB. 

 

All I want is share traffic going over one NIC and docker traffic over another.

Share traffic can continue to be eth0 ... 

[Kristopher]

I'm not trying to be difficult, I just don't get why it needs to be that complicated.

So, if I were to take (what appears to be) the easier way out and remapping my FSTAB to .251, are we saying that unRAID will continue to serve that traffic over eth0?

[bmartino1]

smb is the servers service that you would edit for traffic over the interface.
We don't have access to edit the main unraid servers services config like other linux distro...
NFS is a different server config and has its own config type to set interfaces. NFS is harder to manipulate than smb for share settings. OP was not clear in how they were sharing...

In unriad this is not possible without editing the core service config and setting them to the desired interfaces.
Unraids networking is aimed at the end users for a point and click.

Gotcha!

I apologize for not being complete - I just thought it was a high-level thing like "Shares" and not the protocol.

Thanks for all the exhaustive info. I think my best bet it to just set fstab in the media server to "force" that nic being used.

[Kristopher]

So I get this a lot in my Unifi logs:  

 

Multiple devices are using the same IP address: 172.16.17.252

 

I notice that the two NICs in unRAID flap between one being .251 and both being .252

Any idea why it might be doing this? They are two, physical NICs, different MAC addresses.

Is this part of unRAID's fairly simplistic "click and done" network setup?

[Kristopher]

Sometimes they will show indepenenty, sometimes both as .251 or .262 and sometimes as the 172.17.0.X "bridge"
