go-nat-pmp
|
||
|
|
==========
|
||
|
|
|
||
|
|
A Go language client for the NAT-PMP internet protocol for port mapping and discovering the external
|
||
|
|
IP address of a firewall.
|
||
|
|
|
||
|
|
NAT-PMP is supported by Apple brand routers and open source routers like Tomato and DD-WRT.
|
||
|
|
|
||
|
|
See http://tools.ietf.org/html/draft-cheshire-nat-pmp-03

Get the package
|
||
|
|
---------------
|
||
|
|
|
||
|
|
go get -u github.com/jackpal/go-nat-pmp
|
||
|

|
||
|
|
Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
import natpmp "github.com/jackpal/go-nat-pmp"
|
||
|
|
|
||
|
|
client := natpmp.NewClient(gatewayIP)
|
||
|
|
response, err := client.GetExternalAddress()
|
||
|
|
if err != nil {
|
||
|
|
return
|
||
|
|
}
|
||
|
|
print("External IP address:", response.ExternalIPAddress)
|
||
|
|
|
||
|
|
Notes
|
||
|
|
-----
|
||
|
|
|
||
|
|
There doesn't seem to be an easy way to programmatically determine the address of the default gateway.
|
||
|
|
(Linux and OSX have a "routes" kernel API that can be examined to get this information, but there is
|
||
|
|
no Go package for getting this information.)
