static const struct GNUNET_CONFIGURATION_Handle * cfg
Configuration we are using.

GN_ReversalCallback cb
Function to call if we receive a reversal request.
struct HelperContext * GN_start_gnunet_nat_server_(const struct in_addr *internal_address, GN_ReversalCallback cb, void *cb_cls, const struct GNUNET_CONFIGURATION_Handle *cfg)
Start the gnunet-helper-nat-server and process incoming requests.
int GN_request_connection_reversal(const struct in_addr *internal_address, uint16_t internal_port, const struct in_addr *remote_v4, const struct GNUNET_CONFIGURATION_Handle *cfg)
We want to connect to a peer that is behind NAT.
static struct GNUNET_ARM_Handle * h
Connection with ARM.
Definition: gnunet-arm.c:99
void GN_stop_gnunet_nat_server_(struct HelperContext *h)
Start the gnunet-helper-nat-server and process incoming requests.
struct in_addr internal_address
IP address we pass to the NAT helper.
configuration data
Definition: configuration.c:85
void * cb_cls
Closure for cb.
void(* GN_ReversalCallback)(void *cls, const struct sockaddr_in *ra)
Function called whenever we get a connection reversal request from another peer.
Information we keep per NAT helper process.
