| 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 " "<ipaddr>-<ipaddr>" | |
| 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 | |
| .TP | |
| .B "--random" | |
| Port mapping will be forcely randomized to avoid attacks based on | |
| port prediction (kernel >= 2.6.21). |
