Set up IP addresses

1. Browse the ALOHA WUI.

2. Open the Services tab.

3. Click Setup on the line corresponding to the network interface you want to manage.

4. Add, remove, or edit the IP address directive using the syntax below:

   ip address <ip/mask>

   service network eth0
   ip address 192.168.1.11/24

5. Click OK.

6. Click Close.

7. The line corresponding to the Network Interface now appears in orange with the flag Need apply.

   

8. Click Reload.

In case of a problem:

• Check for duplicate IPs

Set up IP aliases

You set up IP aliases in the same way as IP addresses.

When you add an IP alias, we recommend that you use a /32 subnet.

Configure the global default gateway

1. Browse the ALOHA WUI.

2. Open the Services tab.

3. Click Setup on the line corresponding to the network interface you want to manage.

4. Add, remove, or edit the global default gateway address directive using the syntax below:

   ip route default <gw>

   service network eth0
     ip address 192.168.1.11/24
     ip route default 192.168.1.1

5. Click OK.

6. Click Close.

7. The line corresponding to the Network Interface now appears in orange with the flag Need apply.

   

8. Click Reload .

In case of problems:

• Try to ping the gateway

• Check the ALOHA routing table

• Check for duplicate IPs

Configure a default gateway per interface

In the ALOHA, it is possible to add default gateways for each network interface. These gateways must have a metric whose value is unique and higher than 0.

Usually, HAProxy uses these to force alternative default gateways when clients or servers can't be reached by the global default gateway or to force a different route for some subnets without setting too many static routes.

1. Browse the ALOHA WUI.

2. Open the Services tab.

3. Click Setup on the line corresponding to the network interface on which you want to manage the global default gateway.

4. Add, remove, or edit the interface default gateway directive using the syntax below:

   ip route default <gw> metric <weight>

   service network eth1
     ip address 192.168.2.11/24
     ip route default 192.168.2.1 metric 10

5. Click OK.

6. Click Close.

7. The line corresponding to the Network Interface now appears in orange with the flag Need apply.

   

8. Click Reload .

In case of problems:

• Try to ping the gateway

• Check the ALOHA detailed routing table

• Check for duplicate IPs

Add static routes

1. Browse the ALOHA WUI.

2. Open the Services tab.

3. Click Setup on the line corresponding to the network interface you want to manage.

4. Add, remove, or edit the IP route directive using the syntax below:

   ip route <ip/mask> <gw>

   service network eth0
     ip address 192.168.1.11/24
     ip route default 192.168.1.1
     ip route 10.0.0.0/24 192.168.1.2
     ip route 172.16.0.0/24 192.168.1.2

5. Click OK.

6. Click Close.

7. The line corresponding to the Network Interface now appears in orange with the flag Need apply.

   

8. Click Reload .

In case of a problem:

• Try to ping the gateway

• Check the ALOHA routing table

Duplicated IPs

To troubleshoot duplicated IPs, you can use the ARP who-has diagnostic tool.

This tool checks if the MAC address associated with the IP address is the one expected or not:

• If yes, the problem may be on an upper layer

• If not, the MAC address of the server has the duplicated IP

Ping

You can use the ping diagnostic tool to try to reach an IP address on the network.
