Struct netsim_embed_nat::Ipv4Nat

pub struct Ipv4Nat { /* private fields */ }

An Ipv4 NAT.

Implementations

impl Ipv4Nat

pub fn new( public_plug: Plug, private_plug: Plug, public_ip: Ipv4Addr, subnet: Ipv4Range ) -> Self

pub fn set_port_allocator<T: Clone + PortAllocator + 'static>( &mut self, port_allocator: T )

Set the port allocator.

pub fn set_hair_pinning(&mut self, hair_pinning: bool)

Enable/disable hair-pinning.

pub fn forward_port( &mut self, port: u16, local_addr: SocketAddrV4, protocol: Protocol )

Manually forward a port.

pub fn set_blacklist_unrecognized_addrs( &mut self, blacklist_unrecognized_addrs: bool )

Causes the NAT to permanently block all traffic from an address A if it recieves traffic from A directed at an endpoint for which it doesn’t have a mapping.

pub fn set_restrict_endpoints(&mut self, restrict_endpoints: bool)

Only allow incoming traffic on a port from remote addresses that we have already sent data to from that port. Makes this a port-restricted NAT.

pub fn set_symmetric(&mut self, symmetric: bool)

Makes this NAT a symmetric NAT, meaning packets sent to different remote addresses from the same internal address will appear to originate from different external ports.

Trait Implementations

impl Debug for Ipv4Nat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Future for Ipv4Nat

type Output = ()

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
