How to restrict admin panel to be accessible from only one IP

I am shocked today - somehow i found today on my SIP server that there is endpoint and routing group created. My SIP server is with public ip address, but with very strong 30 chars password - how it is possible to be hacked? Is there a security leak of the OpenVox software ?

Hi,sir

can you tell me what device you use?

WGW1002G

you can enable firewall and add white/black list in Security Settings and Security Rules .

Where is this in the UI of this model? I can't find it.

Hi, sir

If you have never visited the web interface, it should be the default IP, which is 172.16.99.1.
btw, you need to add this net segment to the network adapter, and after you change the network settings of the device you can connect them to LAN.
