augustynr Assuming I understand your configuration, running two subnet networks on the same vlan id is a little odd? Having said that if you have no wish for security between both networks and run only one dhcp server you should be fine.
I believe the more flexible configuration for running multiple vlan is to configure a Trunk between the Server Ethernet port and the Switch only applicable if your Switch support at least layer 2
The trunk configuration on the Switch should be statically configured. You associate your Trunk to as many vlan's you want and choose the vlan for your pc ports.
I run an ESXI server in a very similar way the only difference is I have a Trunk running between my ESXI Virtual Switch and my Physical Switch but I would think connecting a ClearOS Server to the Switch should work the same way.
Nick I am currently working on a script that will allow you to add, modify & delete list based on a configuration file for both Snort and IPSET to consume.
As I am doing some testing with my script I noticed that the list coming from the emergingthreats servers are not always very well synchronised: Server 1 and Server 2
Just to say that this highlight a logic problem with your script. Your script might fetch different versions for FWrev & emerging-Block-IPs.txt
To fix the problem would be to or find the revision number in emerging-Block-IPs.txt or use the WGET -N option and compare dates. I personally use the latter for my script. I would share my script and post it but it is not ready yet.
Luis you can not install ESXI on a ClearOS server. I have not seen that configuration since version 2 or 3 of VmWare. ESXI takes control of the hardware so it will never be a client.
On the up side ClearOS runs well on ESXI. I even have ESXI running on an old ASUS board. If you have an external Level 2 switch all the better, you can run all your vlan's on a single ethernet card by configuring a trunk.
