Hello all,

I installed whm on a xenserver virtual machine few weeks ago,then I restore the accounts from the existing whm server which is on a public server.the new one just fir backup in case the existsing server crash(if that i only change the domain on whois and nameserver is ok).
What should i do?
the new server local ip is 10.4.xxx.xxx and public ip is 103.28.xxx.xxx
the old server ip is 203.73.xxx.xxx
I really dont know how nat ,I try to visit https://103.28.xxx.xxx:2087 but cant,should I map the 10.4.xxx.xxx port to 103.28.xxx.xxx? and what about the domain on the account? also need map?must map the public ip port 80 or not and which port i need to map?
The nameserver on the new server point to 10.4.xxx.xxx and add a entry use 103.28.xxx.xxx right?
If this i dont know think the system need map 10.4.xxx.xxx to 103.28.xxx.xxx automatically .we can nat it on route.

Hello,

Please ensure you review the following document if you are using a NAT environment:

1:1 NAT

It explains how to map local IP addresses to public IP addresses.

Thank you.

Thank you for reply. I have read it.some of the route port have been used(for example 80 and 8080). I not sure wether it will affect my other applicaton,so I didn't run the last command /scripts/build_cpnat --man.

It said that if the installer detects a NAT-configured network, your server will configure itself for NAT mode and attempt to automatically map local IP addresses to public IP addresses.I remebered i didn't detected,but it also auto map it. and dose it mean I no need to do anything?

Hello,

Could you clarify if your websites are operating as expected or if they are failing to load properly?

Thank you.
