Connecting to a server on physical segment A from physical segment B

I am trying to allow my pc on physical segment A (lan port 1) to connect to my server on physical segment B (lan port 2). I cannot for the life of me figure out how to do this. I have tried creating rules, tried routing. Nothing seems to be working. Anyone have any suggestions?

  By default, all segments can talk to each other. If you want to access A to B, what you can do first is do a ping test from A to B. If that's successful, then likely B has access control to prevent A from talking to it.

  That’s very odd. I have tried deleting all access control rules and am still not having any luck. Lan1 is on 192.168.253.1 and LanB is assigned 192.168.254.1 . Both are on the same subnet. Would this cause the issue?

  Did you ping from one side to the other? If you don't have connectivity, then you are blocking some where. (ping from one side to device on the other)

  Yes I tried pinging from my laptop and other devices that are Lan 1 to my server that is on Lan 2. It won't ping. There are no rules or routes that I can find either. Active Protect is enabled. Could that be the culprit?

  You might have already done this, but have you checked the subnet mask on the server and other devices?

  What should the subnet mask be set to? Can you give me an example?

  You can't have over lapping subnets. example 192.168.1.x and 192.168.2.x is okay, but not 192.168.x.x and 192.168.1.x 

  @David, can you ping other devices on the LAN2? (this is to test and see if your server may be blocking) 

  Active Protect is primarily a WAN blocking feature, it won't touch your LAN.

  Lan 1 is set to 192.168.253.1 and Lan 2 is set to 192.168.254.1 .

  Both of these have subnet mask 255.255.255.0

  No, I cannot ping any of the devices on Lan 2 from Lan 1.

  What kind of rules do you have between the segments? I'd pause them and try again

  Well an update: apparently sometimes Firewalla just needs to be rebooted. 

  That was the only thing I hadn't tried. After making change after change with no results, I just decided to power it off. Few minutes later, powered it back on, and voila it works. I can now access the other segments with no issue. Thanks for the assistance everyone!
