Dynamic nat example p.675

[samehesk]

the nat pool ips are from 170.168.2.2 to 170.168.2.254 and the local addresses are from 10.1.1.1 to 10.1.1.254
as i understand that in the dynamic nat mapping is one to one here the number of local addresses is more than the number of global addresses
am i right?
also in the pat example on page 679 i don't understand why the 255.255.255.248 musk was used with ip pool from 192.1.2.109 to 192.1.2.114 is it becuase the number of global ips is 6 and the block size is 8 and in case of port conflict and changing the ip can the ips 192.1.2.111,192.1.2.112
255.255.255.248 be used as a global ip address since they are also a broadcast and subnet addresses?

thanks for the help

am i right?This is possible, the local addresses can sometimes be more than the public addresses available for translation. The caveat on this, when the private addresses used up all the available public addresses the remaining user will not be able to connect to the Internet and they have to wait until another public address becomes available.

Hi Mr.Lammle,

There's a bit of typo error on the last paragraph of Dynamic NAT topic

The ip nat pool todd 170.168.2.2 192.168.2.254 command creates a pool of
addresses that will be distributed to those hosts that require NAT.I think the IP addresses in bold should be 170.168.2.254 as stated on the command sample. :)

Cheers!
