===== Robotlab firewalls =====

==== Athans ====

''athans.control.lth.se'' is in front of the [[wp>Subnetwork|subnets]] 
  * ''a.control.lth.se'' (''192.168.65.0/24'')
  * ''b.control.lth.se'' (''192.168.66.0/24'')
  * ''c.control.lth.se'' (''192.168.67.0/24'')
  * ''d.control.lth.se'' (''192.168.68.0/24'')

To access nodes behind athans you will need to [[tutorials:add_network_routes|add network routes]] for each subnet with athans IP address as gateway (currently ''130.235.83.152''). 

You will also need a wired connection to Automatic Control's part of LU's network (130.235.83.0/24).

Robots are configured for all 4 subnets but usually only connected to one. Test pinging them to figure out if it's A, B, C or D.
