I have a server in Lan.What should I do on firewall when I want to build a validator?

You need to open port UDP to the outside.
Use command netstat -ntlup to see what port the node is using

Thanks

What is the diff between Featured Pools and Nominator Pools on the https://tonvalidators.org page?

Thank you as well, this is an interesting subject 🙂
Do you know any reverse proxy for RLDP (for example, if my server checks incoming connections to be HTTP and allows all outgoing)?

Featured pools are not yet active, and they are looking for nominators to join them, so that they can become an active validator. They are highlighted there, to encourage new nominators to consider them.

Nominator pools are the list of all active and inactive pools.

Thank you.

If I want my pool be displayer on the list of tonvalidators.org ,what should I do?Only charge 10000ton to the pool?

thanks

is it Featured Pools showing new opportunities on the ton network automatically or it is manually and manage by Ton Foundation?

Is it activated or what we see now is active but nobody is interested anymore to help as Nominator to fill the Nominator pool and let the validator be activated and start earning money?
