pub struct GephNat { /* private fields */ }

Implementations

impl GephNat

pub fn new(cap: usize, src_ip: Ipv4Addr) -> Self

pub fn rewrite_upstream_src( &self, original_src: SocketAddrV4, dest: SocketAddrV4, ) -> SocketAddrV4

Given the source and destination addresses of an upstream packet, return the corresponding address on the “up-facing” side of the NAT

pub fn rewrite_downstream_dest( &self, current_dest: SocketAddrV4, src: SocketAddrV4, ) -> Option<SocketAddrV4>

Given the destination and source addresses of a downstream packet, return the corresponding address on the “down-facing” side of the NAT

pub fn mangle_upstream_pkt(&self, msg: &[u8]) -> Option<Bytes>

Given an upstream IP packet, return the mangled version (if it parses successfully)

pub fn mangle_downstream_pkt(&self, msg: &[u8]) -> Option<Bytes>

Given a downstream IP packet, return the mangled form if it parses correctly.
