How to activate response to Ping from NSG50

Hi @Oxygen,

Welcome to Zyxel Community!
You may go to Security gateway > Configure > Firewall page to specify your allowed IPs for Ping.



Feel free to let me know if you have any concern.

@Oxygen,

May you help me to enable Zyxel support at HELP > Support request page and provide me your organization name so that I will have privilege to check your issue.


Thanks,

@Oxygen,

Thanks for your reply.
Sorry, I just see that your issue is your client is unable to ping to LAN2, and I notice that you enable LAN 2 as Guest interface. 


It will make client under this 192.168.91.0/24 subnet unable to ping 192.168.91.1

Hope it helps,

@Oxygen,

I have to rephrase my words that enable Guest feature on LAN interface makes devices have ability to access Internet but cannot communicate to other LAN devices; however, devices on other LANs are able to communicate to devices under LAN interface with Guest enabled.
