Cannot Contact the MIP

Add Interface 1 IP Addresses and MIP to Access List 149

When trying to add a VPN Gateway to a cluster by selecting join in the Setup menu, you may receive an error message stating that the system is unable to contact the Management IP address (MIP).

This could be the case if you are trying to join a VPN Gateway to a cluster and there are existing entries in the Access list. Typically, the Access list contains valid IP addresses for Telnet or SSH management. If the Access list contains entries, you have to add the Interface 1 IP addresses of both VPN Gateways and the Management IP address (MIP) to the Access list before joining the VPN Gateway.

If the Access list is empty, communication should be working fine.

Check the Access List

On the master VPN Gateway, check if there are entries in the Access list. Type the command /cfg/sys/accesslist/list to view the current Access list.

>># /cfg/sys/accesslist/list

1:192.168.128.78, 255.255.255.0

Add Interface 1 IP Addresses and MIP to Access List

Use the /cfg/sys/cluster/cur command to view the Host Interface 1 IP address for the existing VPN Gateway. Then add this IP address, the intranet IP address you had in mind for the new VPN Gateway and the Management IP address (MIP) to the Access list.

To add the IP addresses to the Access list, type the command /cfg/sys/accesslist/add.

>># /cfg/sys/accesslist/add

Enter network address: <IP address>

Enter netmask: <network mask>

Try adding the VPN Gateway to the cluster using the join command in the Setup menu.

If a software version earlier than 2.0.11.16 is running in the cluster, and software version 3.1 or later is installed on the VPN Gateway you want to join, perform the steps described in “Reinstalling the Software” (page 70). If there is still a difference in software version after this, you need to adjust the software version on the VPN Gateway you want to add as well.
