I want to know how to configure 1 to 1 nat in any ip range.
I want to configure 1-to-1 nat bellow.
e.g.) matching 4th octet number
10.200.20.1 -> 192.168.100.1
10.200.20.2 -> 192.168.100.2
10.200.20.52 -> 192.168.100.52
I configured nat with ip range. (see bellow)
set interfaces dummy dum1 address '192.168.100.1/24'
set nat source rule 10 outbound-interface 'tun1'
set nat source rule 10 source address '10.200.20.0/24'
set nat source rule 10 translation address '192.168.100.0/24'
I can see a nat translation that matched 4th octet numbers.
$ sh nat source translations
Pre-NAT Post-NAT Prot Timeout
10.200.20.76 192.168.100.76 icmp 11
In this case, is this nat translation always maintained ?
