| 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 |
| \fB--to\fP \fIipaddr\fP[\fB-\fP\fIipaddr\fP] |
| 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 forcibly randomized to avoid attacks based on |
| port prediction (kernel >= 2.6.21). |
