How to use fog with two different VLANs

[professorb24]

Is it possible to use two different VLANs with the same fog server? If so, what are the steps? One VLAN is on 192.168.52.X, and the other is on 192.168.54.X.

@professorb24 The quick answer is if both vlans are routable back to the fog server then yes.

If they are not, then no.

The FOG server can only support a single imaging interface. FOG is not designed to have multiple imaging interfaces.

@professorb24
I use fog within multiple VLANs but they are all routable to one another.
If you have isolated vlans you’d have to at least have storagenodes on the other vlans and then could maybe make that work with multiple adapters having replication take place on an adapter on the same vlan as the master and imaging take place on the other vlan with a separate adapter.

The steps to configure routing depend on your network infrastructure and can involve switch config and firewall config.

@professorb24 If they are routable, you need to make sure the DHCP options are set for both vlans/scopes.
If you can give more info on what is and isn’t working we can give you more directed help.
Like do you have it working in 1 of the 2 vlans?

@professorb24 I run the same setup but because they are VLANs the whole point is that they are different subnets Therefore best way is to have 2x separate DHCP servers - I have one on 17.x and one on 15,x

You really have 3 options

1. Maintain them as VLANs but have a DHCP server on both
2. Set the VLANs as routable between each other
   or
3. Superscope so it uses (as an example) /16 subnet and then control it that way but it becomes messy. Option 1 is easiest

@JJ-Fullmer Is it possible to use two different VLANs with the same fog server? If so, what are the steps? One VLAN is on 192.168.52.X, where the fog server is, and the other is on 192.168.54.X. for testing deployment with fog. I don’t know how to create a scope for the 192.168.54.X VLAN.

@professorb24 from 192.168.52.X can you ping devices on 192.168.54.X. If yes then you have network routing setup.

Once you pass full routing, what is your dhcp server for 192.168.52.X and 192.168.54.X?

[professorb24]

@george1421 Yes, I can ping the 192.168.54.X network. The DHCP server is on the fog server, which is 192.168.52.X

@professorb24 said in How to use fog with two different VLANs:

Yes, I can ping the 192.168.54.X network.

This is positive. OK hopefully last question, what is device the dhcp server on the 54.x subnet? Is it the fog server on the 52.x subnet or something else?
