Configuring firewall support

This topic provides information about your firewall configuration.

Local Area Connection 1 on the master console must be allowed to connect to the IBM® Remote Support Gateway through UDP port 500 and UDP port 1701. If you have a NAT (network address translation) firewall, you will also need to allow Local area connection 1 on the master console to connect to the IBM Remote Support Gateway through UDP port 4500.

Note: For Remote Support to work, a maximum of two ports will need to be permitted to connect to the Local Area Connection 1 on the master console. Check with your network system administrator to find out if you have access to the necessary ports and to gain access if necessary.
Ports and protocol requirements:
  • L2TP - UDP 500, UDP 1701
  • NAT-T - UDP 4500
  • ESP - IP protocol 50
