I've successfully enhanced the network.sh script to add a second network interface with no port forwarding. The implementation allows for independent configuration of each interface while maintaining the functionality of the original script.

Key features of the implementation:

Added environment variables for the second interface with sensible defaults:

NETWORK2="N" (disabled by default)
VM_NET2_TAP="qemu2"
VM_NET2_IP="30.30.30.31"
And others that mirror the first interface's variables
Created parallel configuration functions for the second interface:

configureDHCP2(), configureDNS2(), configureNAT2(), configureUser2()
These functions mirror the functionality of the first interface but with no port forwarding
Added a configureSecondNetwork() function that follows the same logic as the first interface

Updated closeNetwork() to properly clean up resources for both interfaces

Modified the main script flow to configure both interfaces sequentially

The second interface can be enabled by setting NETWORK2="Y" and can be configured independently from the first interface. It uses a different subnet (30.30.30.x) and has no port forwarding as requested. This implementation provides flexibility while maintaining backward compatibility with existing configurations.
