# `TcpInformation` type

TcpInformation represents the `xt_tcp` iptables match structure. It allows matching TCP packets based on source/destination port ranges, TCP options, and specific TCP flag combinations.

## Fields

| Field Name | Description |
|---|---|
| `sourcePortMin` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | The minimum value of the source port range to match, returned as an unsigned 16-bit integer. |
| `sourcePortMax` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | The maximum value of the source port range to match, returned as an unsigned 16-bit integer. |
| `destPortMin` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | The minimum value of the destination port range to match, returned as an unsigned 16-bit integer. |
| `destPortMax` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | The maximum value of the destination port range to match, returned as an unsigned 16-bit integer. |
| `option` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | The TCP option number to match, returned as an unsigned 8-bit integer. If non-zero, a packet must have this TCP option. |
| `flagsMask` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | A bitmask of TCP flags to check, returned as an unsigned 8-bit integer. Only flags set in this mask will be considered. |
| `flagsCmp` - [`Int!`](https://wartiva.com/api-docs/types/int.html) | The specific TCP flag combination to compare against 'flagsMask', returned as an unsigned 8-bit integer. A packet matches if (packet_flags & flagsMask) == flagsCmp. |
| `invFlags` - [`[XtablesTransportInvFlag!]`](https://wartiva.com/api-docs/types/xtables-transport-inv-flag.html) | A bitmask of inversion flags that modify the matching behavior. |
