Pull Request Overview
This PR modifies ForwardedPortRemote to support optional BoundHost specification, allowing the bound host address to be null to simulate SSH remote port forwarding commands like ssh -R 80:127.0.0.1:5000 [email protected].
Key Changes:
- Removed the null check for
boundHostAddressparameter in the main constructor - Modified the constructor chain to pass
nullinstead of empty string whenboundHostis not specified - Updated the
BoundHostproperty getter to handle nullBoundHostAddress

Direct array indexing without bounds checking could throw IndexOutOfRangeException if GetHostAddresses returns an empty array. Consider adding validation to ensure the array is not empty before accessing the first element.

When using overload ForwardedPortRemote without boundHost parameter it is still transmitted as empty string and then resolved by DnsAbstraction.GetHostAddresses -> '::1'.
This is necessary to simulate ssh command like this
ssh -R 80:127.0.0.1:5000 [email protected](https://localhost.run/docs/)
