Additional IP pools

[strike101]

How to do this in pfsense ?

I just change the netmask to /23 , then this will increase the available ip pool , i just add the ip range at the dhcp server ?

no more additional settings on the dns or firewall / nat ?

thanks

The DHCP pool is a separate setting on the DHCP page.  Address range has nothing to do with DNS.  You configure the DNS records to match the host address.  NAT is only a factor, if you have rules for incoming traffic.
