You know, it's a pretty typical setup for a small home network. One subnet, cause that's all I need, I have 5 ethernet ports on the machine, the first one is attached to the network for file serving duties and for administration. The next two are in a link aggregation lagg that is only there to serve my jail that's attached to it and the final two are unattached and undefined. I original had the first three in a link aggregation lagg, but the response times from the jail and the main file server was atrocious. When I split the two, the response times became good again, but I was originally able to set them up in the same subnet, along with the jail in the same subnet and it worked a treat. Experimented with round robin lagg to see if that was better, but it certainly was not. Then I changed it back to link aggregation and that's when the subnet error bit me and I had to set the lag to DHCP, which puts it in the same network segment, and it works a treat now. Now, I understand what the article is saying and even though it shouldn't work, it does. And telling me to setup another subnet with all of the associated problems with firewalls and everything else just to put a lagg on the network is not on my todo list when having them in the same network does me well. Just telling me that that's the solution when it worked before and works now is not a real explanation as to why I "shouldn't" be able to do it.
