Fail to change IP gateway on ATD 5.0.0.11

[tonysssbear]

Hi Everyone,

We are trying to change our netmask from /24 to /16, which is fail

anyone have idea what's wrong on it?

Procedure 1

1. set appliance ip 192.168.1.100 255.255.0.0

2. show intfport mgmt (netmask show /16)

3. reboot the ATD

4. show intfport mgmt (netmask return to /24)

2nd procedure

1. set appliance ip dhcp

2. rebbot (appliance spend a lot time to reboot)

3. appliance cannot get ip (no dhcp server)

4. show intfport mgmt (show "0" on ip)

5. set appliance ip 192.168.1.100 255.255.0.0

6. reboot

7. show intfport (subnet return to /24)

Regards

Tony

I guess, that there is a conflict with internal ATD VM network which is 192.168.122.0/24. And ATD is also using other subnets from 192.168. for other components.

192.168.122.0/24 is included in 192.168.0.0/16 which you are trying to use.

You can change internal network, but to 3 of expected values: https://docs.trellix.com/pl/bundle/advanced-threat-defense-4.12.x-command-line-interface-reference-g...
