1515 DESCRIPTION
1616 nat-traverse establishes connections between nodes which are behind NAT
136136 above.
137137
138138 Setup of a VPN with OpenVPN
139 You can use <OpenVPN> over nat-traverse if you want to have a *secure*
140 VPN.
139 You can use OpenVPN <https://openvpn.net/> over nat-traverse if you want
140 to have a *secure* VPN.
141141
142142 Using OpenVPN over nat-traverse requires only one change to OpenVPN's
143143 configuration file, presuming that you don't want to use OpenVPN's
188188 port numbers are (in general) not predictable.

13 Description: NAT gateway traversal utility
14 nat-traverse establishes connections between nodes which are
15 behind NAT gateways, i.e. hosts which do not have public IP
16 addresses. Additionally, you can setup a small VPN by using pppd
17 on top of nat-traverse. nat-traverse does not need an external
18 server on the Internet, and it isn't necessary to reconfigure
19 the involved NAT gateways, either. nat-traverse works
20 out-of-the-box.

158163 Limitation: nat-traverse does not work with gateways which change the port
159164 numbers. This is a fundamental problem of nat-traverse's design, as the changed
