Similar to SNAT/DNAT depending on chain: it takes a range of addresses (`--to 1.2.3.4-1.2.3.7') and gives a client the same source-/destination-address for each connection. .TP .BI "--to " "-" Addresses to map source to. May be specified more than once for multiple ranges. .TP .B "--nodst" Don't use the destination-ip in the calculations when selecting the new source-ip
