157 While I2P will work fine behind most firewalls, your speeds and network integration will generally improve
158 if the I2P port (generally 8887) is forwarded for both UDP and TCP.
159 </p><p>
160 If you can, please poke a hole in your firewall to allow unsolicited UDP and TCP packets to reach
161    you.  If you can't, I2P supports UPnP (Universal Plug and Play) and UDP hole punching
162    with "SSU introductions" to relay traffic. Most of the options above are for special situations,
163    for example where UPnP does not work correctly, or a firewall not under your control is doing
164    harm. Certain firewalls such as symmetric NATs may not work well with I2P.

170 UPnP is used to communicate with Internet Gateway Devices (IGDs) to detect the external IP address
171 and forward ports.
172 UPnP support is beta, and may not work for any number of reasons:
173 <ul>
174<li class="tidylist">No UPnP-compatible device present
175<li class="tidylist">UPnP disabled on the device
176<li class="tidylist">Software firewall interference with UPnP
177<li class="tidylist">Bugs in the device's UPnP implementation
178<li class="tidylist">Multiple firewall/routers in the internet connection path
179<li class="tidylist">UPnP device change, reset, or address change
180 </ul><br>
181 Reviewing the <a href="peers.jsp#upnp">UPnP status</a> may help.
182 UPnP may be enabled or disabled above, but a change requires a router restart to take effect.
183 </p><p>Hostnames entered above will be published in the network database.
184    They are <b>not private</b>.
185    Also, <b>do not enter a private IP address</b> like 127.0.0.1 or 192.168.1.1.
186    If you specify the wrong IP address or
187    hostname, or do not properly configure your NAT or firewall, your network performance will degrade
188    substantially.  When in doubt, leave the settings at the defaults.</p>

191 <p>
192 While I2P will work fine behind most firewalls, your speeds and network integration will generally improve
193 if the I2P port (generally 8887) to both UDP and TCP.
194 If you think you have opened up your firewall and I2P still thinks you are firewalled, remember
195 that you may have multiple firewalls, for example both software packages and external hardware routers.
196 If there is an error, the <a href="logs.jsp">logs</a> may also help diagnose the problem.
197 <ul>
198<li class="tidylist"><b>OK</b> - Your UDP port does not appear to be firewalled.
199<li class="tidylist"><b>Firewalled</b> - Your UDP port appears to be firewalled.
200     As the firewall detection methods are not 100% reliable, this may occasionally be displayed in error.
201     However, if it appears consistently, you should check whether both your external and internal
202     firewalls are open on port 8887. I2P will work fine when firewalled, there is no reason for concern.
203     When firewalled, the router uses "introducers" to relay inbound connections.
204     However, you will get more participating traffic and help the network more if you can open your
205     firewall(s). If you think you have already done so, remember that you may have both a hardware
206     and a software firewall, or be behind an additional, institutional firewall you cannot control.
207     Also, some routers cannot correctly forward both TCP and UDP on a single port, or may have other
208     limitations or bugs that prevent them from passing traffic through to I2P.
209<li class="tidylist"><b>Testing</b> - The router is currently testing whether your UDP port is firewalled.
210<li class="tidylist"><b>Hidden</b> - The router is not configured to publish its address,
211     therefore it does not expect incoming connections.
212<li class="tidylist"><b>WARN - Firewalled and Fast</b> - You have configured I2P to share more than 128KBps of bandwidth,
213     but you are firewalled. While I2P will work fine in this configuration, if you really have
214     over 128KBps of bandwidth to share, it will be much more helpful to the network if
215     you open your firewall.
216<li class="tidylist"><b>WARN - Firewalled and Floodfill</b> - You have configured I2P to be a floodfill router, but
217     you are firewalled. For best participation as a floodfill router, you should open your firewall.
218<li class="tidylist"><b>WARN - Firewalled with Inbound TCP Enabled</b> - You have configured inbound TCP, however
219     your UDP port is firewalled, and therefore it is likely that your TCP port is firewalled as well.
220     If your TCP port is firewalled with inbound TCP enabled, routers will not be able to contact
221     you via TCP, which will hurt the network. Please open your firewall or disable inbound TCP above.
222<li class="tidylist"><b>WARN - Firewalled with UDP Disabled</b> -
223     You have configured inbound TCP, however
224     you have disabled UDP. You appear to be firewalled on TCP, therefore your router cannot
225     accept inbound connections.
226     Please open your firewall or enable UDP.
227<li class="tidylist"><b>ERR - Clock Skew</b> - Your system's clock is skewed, which will make it difficult
228     to participate in the network. Correct your clock setting if this error persists.
229<li class="tidylist"><b>ERR - Private TCP Address</b> - You must never advertise an unroutable IP address such as
230     127.0.0.1 or 192.168.1.1 as your external address. Correct the address or disable inbound TCP above.
231<li class="tidylist"><b>ERR - SymmetricNAT</b> - I2P detected that you are firewalled by a Symmetric NAT.
232     I2P does not work well behind this type of firewall. You will probably not be able to
233     accept inbound connections, which will limit your participation in the network.
234<li class="tidylist"><b>ERR - UDP Port In Use - Set i2np.udp.internalPort=xxxx in advanced config and restart</b> -
235     I2P was unable to bind to port 8887 or other configured port.
236     Check to see if another program is using port 8887. If so, stop that program or configure
237     I2P to use a different port. This may be a transient error, if the other program is no longer
238     using the port. However, a restart is always required after this error.
239<li class="tidylist"><b>ERR - UDP Disabled and Inbound TCP host/port not set</b> -
240     You have not configured inbound TCP with a hostname and port above, however
241     you have disabled UDP. Therefore your router cannot accept inbound connections.
242     Please configure a TCP host and port above or enable UDP.
243<li class="tidylist"><b>ERR - Client Manager I2CP Error - check logs</b> -
244     This is usually due to a port 7654 conflict. Check the logs to verify. Do you have another I2P instance running?
245     Stop the conflicting program and restart I2P.

252 <p>
253 This setting causes your router identity to be regenerated every time your IP address
254 changes. If you have a dynamic IP this option can speed up your reintegration into
255 the network (since people will have shitlisted your old router identity), and, for
256 very weak adversaries, help frustrate trivial
257 <a href="http://www.i2p.net/how_threatmodel#intersection">intersection
258 attacks</a> against the NetDB.  Your different router identities would only be
259 'hidden' among other I2P users at your ISP, and further analysis would link
260 the router identities further.</p>
261 <p>Note that when I2P detects an IP address change, it will automatically
262 initiate a restart in order to rekey and to disconnect from peers before they
263 update their profiles - any long lasting client connections will be disconnected,
264 though such would likely already be the case anyway, since the IP address changed.
