Smoothwall + VLANs

[localzuk]

We currently have a fairly basic Smoothwall routing setup on our pair of appliances and need to make some changes for our new network setup.

 

Specifically, at the moment, 0.0.0.0/0 is routed by our core switch to an interface on our smoothwall box, 10.10.0.1. This is set up in Smoothwall as a basic interface. No vlans etc...

 

I need to add a VLAN with gateway IP 10.99.0.1 to that same interface but if I go to Add new interface, it doesn't allow me to select the above as a parent interface.

 

So, my question is - do I have to delete the IP from the interface, which will make the interface available as a parent interface, and re-add it as a VLAN? And add the new VLAN as a tagged VLAN as well?

Short answer is yes.

 

The carrier of a VLAN can't have an IP. You need to remove the IP, then add it again as a default vlan and then add your new vlan to it as well. You can do this on another interface and then, when ready, swap carrier interface.

Thanks @ibpalle. Only issue is lack of spare interfaces. Will have to dig out some SFP modules and use one of those!
