| 2 | .TP |
| 3 | \fB\-\-dir\fP {\fBin\fP|\fBout\fP} |
| 4 | Used to select whether to match the policy used for decapsulation or the |
| 5 | policy that will be used for encapsulation. |
| 6 | .B in |
| 7 | is valid in the |
| 8 | .B PREROUTING, INPUT and FORWARD |
| 9 | chains, |
| 10 | .B out |
| 11 | is valid in the |
| 12 | .B POSTROUTING, OUTPUT and FORWARD |
| 13 | chains. |
| 14 | .TP |
| 15 | \fB\-\-pol\fP {\fBnone\fP|\fBipsec\fP} |
| 16 | Matches if the packet is subject to IPsec processing. |
| 17 | .TP |
| 18 | \fB\-\-strict\fP |
| 19 | Selects whether to match the exact policy or match if any rule of |
| 20 | the policy matches the given policy. |
| 21 | .TP |
| 22 | [\fB!\fP] \fB\-\-reqid\fP \fIid\fP |
| 23 | Matches the reqid of the policy rule. The reqid can be specified with |
| 24 | .B setkey(8) |
| 25 | using |
| 26 | .B unique:id |
| 27 | as level. |
| 28 | .TP |
| 29 | [\fB!\fP] \fB\-\-spi\fP \fIspi\fP |
| 30 | Matches the SPI of the SA. |
| 31 | .TP |
| 32 | [\fB!\fP] \fB\-\-proto\fP {\fBah\fP|\fBesp\fP|\fBipcomp\fP} |
| 33 | Matches the encapsulation protocol. |
| 34 | .TP |
| 35 | [\fB!\fP] \fB\-\-mode\fP {\fBtunnel\fP|\fBtransport\fP} |
| 36 | Matches the encapsulation mode. |
| 37 | .TP |
| 38 | [\fB!\fP] \fB\-\-tunnel\-src\fP \fIaddr\fP[\fB/\fP\fImask\fP] |
| 39 | Matches the source end-point address of a tunnel mode SA. |
| 40 | Only valid with \fB\-\-mode tunnel\fP. |
| 41 | .TP |
| 42 | [\fB!\fP] \fB\-\-tunnel\-dst\fP \fIaddr\fP[\fB/\fP\fImask\fP] |
| 43 | Matches the destination end-point address of a tunnel mode SA. |
| 44 | Only valid with \fB\-\-mode tunnel\fP. |
| 45 | .TP |
| 46 | \fB\-\-next\fP |
| 47 | Start the next element in the policy specification. Can only be used with |
| 48 | \fB\-\-strict\fP. |
