I have an issue with my new server detecting the wrong IP.
My local IP: 172.16.7.17 points to public IP: 103.16.62.79 and it works fine with installing HestiaCP successfully.
When I check the Hestia panel network it uses 172.16.7.17 → 103.16.62.80 and I edit and change it back to 172.16.7.17 → 103.16.62.79 and it works without any error.
I also use v-list-sys-ips to check IP also correct 172.16.7.17 → 103.16.62.79
The problem when i send email test with Roundcube the sender IP is 103.16.62.80 not 103.16.62.79
We are talking about two different things, one thing is input (website) and the other thing is output (sending mails)
So, your default gateway is using 103.16.62.80.
Yeah, I know, if I told you to execute a command is to view the output .
Anyway, with traceroute command you would see the routes it is using to reach the website ip.hestiacp.com and you will see what is the gateway it is using. I’ve no idea how you have configured your network and/or router but by default you are using 103.16.62.80 instead of 103.16.62.79.
