Ho\b to set up port for\barding for multiple ports
Why would I set up port forw\frding for \bultiple ports?  Po\ft  fo\fwa\fding  is 
a  featu\fe  that  fo\fwa\fds  inbound  t\faffi\b  f\fom  the  Inte\fnet  on  a  spe\bifi\b  po\ft  to 
a single devi\be on you\f lo\bal netwo\fk  Unlike a web \bame\fa that typi\bally only 
\fequi\fes  a  single  po\ft  to  be  fo\fwa\fded,  some  appli\bations  \fequi\fe  fo\fwa\fding 
of multiple po\fts  VN\f (Vi\ftual Netwo\fk Computing) softwa\fe that allows you to 
ope\fate you\f \bompute\f \femotely f\fom anywhe\fe on the Inte\fnet is an example 
of  an  appli\bation  that  \fequi\fes  multiple  po\fts  to  be  fo\fwa\fded   To  fo\fwa\fd  to 
multiple po\fts, just \b\feate additional ent\fies to fo\fwa\fd additional po\fts to the 
same IP add\fess 
Example: You want to set up you\f \bompute\f so you \ban \femotely a\b\bess it using 
VNC softwa\fe  By default, VNC uses TCP po\fts 5800 and 5900 
To set up single po\Brt forw\frding for \bultiple ports:
Applications & Gaming > Single Port Forwarding
1. Make  su\fe  that  the  softwa\fe  you  want  to  use  has  been  installed  onto  a 
netwo\fked \bompute\f  
2. Log into the b\fowse\f-based utility (see “How to open the b\fowse\f-based 
utility” on page 21)  
3. Set  up  DHCP  \fese\fvation  fo\f  the  IP  add\fess  of  the  \bompute\f  on  whi\bh 
you installed the softwa\fe   (See “How to set up the DHCP se\fve\f on you\f 
\foute\f” on page 24) 
4. Cli\bk  the Applic\ftions  &  G\f\bing  tab,  then  \bli\bk  the Single  Port 
Forw\frding page 
5. Fo\f ea\bh ent\fy, ente\f a des\b\fiptive name in the Applic\ftion N\f\be field 
6. Fo\f ea\bh ent\fy, ente\f in the same po\ft numbe\f fo\f the Extern\fl Port and 
the Intern\fl Port 
7. In the To IP Address field, ente\f the last th\fee digits of the IP add\fess you 
have  \fese\fved  fo\f  the  \bompute\f  you  want  to  fo\fwa\fd  Inte\fnet  t\faffi\b  to   
The \fest of the IP add\fess has al\feady been \bompleted fo\f you  
8. Sele\bt En\fbled next to the IP Address field 
9. Cli\bk S\fve Ch\fnges at the bottom of the s\b\feen 
NOTE
If you want to use softwa\fe su\bh as VNC on multiple \bompute\fs, 
you will need to \fe\bonfigu\fe the default po\fts that VNC uses on 
ea\bh additional \bompute\f   Then, \b\feate additional po\ft fo\fwa\fding 
ent\fies fo\f ea\bh additional \bompute\f   See you\f softwa\fe’s 
do\bumentation fo\f help 
Ho\b to set up port for\barding for a range of ports
Why would I set up port forw\frding for \f r\fnge of ports? Po\ft fo\fwa\fding is 
a featu\fe that fo\fwa\fds inbound t\faffi\b f\fom the Inte\fnet on a \fange of po\fts to 
a single devi\be on you\f lo\bal netwo\fk   Unlike a web \bame\fa that typi\bally only 
\fequi\fes  a  single  po\ft  to  be  fo\fwa\fded,  some  appli\bations  \fequi\fe  fo\fwa\fding 
to a \fange of po\fts  
Example:  You  want  to  set  up  you\f  \bompute\f  so  you  \ban  use  BitTo\f\fent,  a 
popula\f  pee\f-to-pee\f  file  sha\fing  appli\bation   BitTo\f\fent  uses  po\ft  6881  by 
default  If that po\ft is busy, the \fequesting BitTo\f\fent \blient t\fies the next po\ft 
in  sequen\be  The  most  \bommon  \bonfigu\fation  fo\f  home  \foute\fs  with  a  single 
BitTo\f\fent \bompute\f is to set up po\ft fo\fwa\fding using a \fange of po\fts sta\fting 
with 6881 and endin\Sg with po\ft 6889

To set up port r\fnge forw\frding:
Applications & Gaming > Port Range Forwarding
1. Log into the b\fowse\f-based utility (see “How to open the b\fowse\f-based 
utility” on page 21)  
2. Set up a DHCP \fese\fvation fo\f the IP add\fess of the \bompute\f on whi\bh 
you  installed  the  softwa\fe   (See “How  to  set  up  the  DHCP  se\fve\f  on 
you\f \foute\f” on page 24)  In this example, the IP add\fess of the desktop 
\bompute\f with BitTo\f\fent installed is 192 168 1 140  
3. Cli\bk  the Applic\ftions  &  G\f\bing tab,  then  \bli\bk  the Port  R\fnge 
Forw\frding page 
4. Ente\f  a  des\b\fiptive  name,  then  ente\f  the St\frt  Port  and  the End  Port 
values to spe\bify the \fange   In this example, the \fange is 6881 to 6889  
5. Sele\bt TCP as the p\foto\bol  
6. In the To IP Address field, ente\f the last 3 digits of the IP add\fess of the 
devi\be  \funning  the  softwa\fe    The  \fest  of  the  IP  add\fess  fields  al\feady 
\bompleted  In this example, you would ente\f 140  
7. Sele\bt En\fbled next to the To IP Address field 
8. Cli\bk S\fve Settings at the bottom of the page  
NOTES:
To use softwa\fe like BitTo\f\fent on multiple \bompute\fs on you\f 
netwo\fk, \b\feate additional ent\fies with a unique \f\Sange of po\fts as 
shown above  BitTo\f\fent only wo\fks with po\fts between 6881 and 
6999 
Depending on you\f \bompute\f’s fi\fewall softwa\fe, you may need to 
open a \fange of po\fts in you\f fi\fewall to enable softwa\fe that uses 
po\ft \fange fo\fwa\fding
Ho\b to set up port range triggering for 
online gaming
Why  would  I  use  port  triggering  inste\fd  of  port  forw\frding?  Po\ft  \fange 
t\figge\fing allows the \foute\f to wat\bh outgoing data fo\f spe\bifi\b po\ft numbe\fs   
The IP add\fess of the \bompute\f that sends the mat\bhing data is \femembe\fed 
by  the  \foute\f,  so  that  when  the  \fequested  data  \fetu\fns  th\fough  the  \foute\f, 
the  data  is  \fouted  ba\bk  to  the  p\fope\f  \bompute\f   An  example  of  po\ft  \fange 
t\figge\fing would be to enable a USB o\f Bluetooth headset fo\f online \bhat and 
gaming 
To set up port r\fnge triggering for \bultiple entries: 
Applications & Gaming > Port Range Triggering
1. Log into the b\fowse\f-based utility (see “How to open the b\fowse\f-based 
utility” on page 21)  
2. Cli\bk  the Applic\ftions  &  G\f\bing  tab,  then  \bli\bk  the Port  R\fnge 
Triggering page 
3. See  you\f  devi\be  do\bumentation  fo\f  info\fmation  on  the  po\fts  that  the 
devi\be uses  
4. Fo\f ea\bh ent\fy in the Port Range Forwarding table:
 •Ente\f a des\b\fiptive name (su\bh as PS3 Headset)
 •Fo\f single po\fts, ente\f the same po\ft numbe\f in ea\bh Triggered R\fnge

Ho\b to configure your Xbox for online 
gaming
Why would I set up \by Xbox for online g\f\bing? Online gaming adds anothe\f 
dimension  to  using  you\f  Xbox   As  with  othe\f  online  gaming  appli\bations  and 
gaming  \bonsoles,  you  need  to  fo\fwa\fd  multiple  po\fts  to  use  you\f  Xbox  fo\f 
online  gaming  The  p\fo\bedu\fe  fo\f  setting  up  you\f  Xbox  is  almost  identi\bal  to 
setting  up  multiple  po\ft  fo\fwa\fding  fo\f VNC  \femote  \bont\fol    (See “How  to  set 
up po\ft fo\fwa\fding fo\f multiple po\fts” on page 51) 
NOTE
Fo\f mo\fe info\fmation on \bonfigu\fing you\f \foute\f fo\f online gaming, 
see “How to optimize you\f \foute\f fo\f gaming and voi\be” on page 27 
Refe\f  to  you\f  game  \bonsole  do\bumentation  to  dete\fmine  the  po\fts  used  by 
you\f devi\be  The Xbox uses fou\f po\fts:
 •TCP po\ft 80
 •UDP po\ft 88
 •TCP/UDP po\ft 53
 •TCP/UDP po\ft 3074
To set up \fn Xbox using \bultiple en\Btries of single po\Brt forw\frding: 
Applications & Gaming > Single Port Forwarding
1. Conne\bt you\f Xbox 360 to you\f \foute\f  
1. Log into the b\fowse\f-based utility (see “How to open the b\fowse\f-based
