3.6 NAT
3.6.1 Virtual Server
If  you  configure  the  router  as  a  virtual  server,  remote  users 
access  services  such  as  Web  or  FTP  at  your  local  site  via 
public  IP  addresses  can  be  automatically  redirected  to 
local  servers  configured  with  private  IP  address.  In  other 
words,  depending  on  the  requested  service  (TCP/UDP  port 
number),  the  router  redirects  the  external  service  request  to 
the appropriate server.
Example:
IDPrivate IPPrivate PortTypePublic PortComment
1192.168.2.20200TCP80  Web Server
2192.168.2.12333TCP21  FTP Server

IP  host)  to  wihich  the  Public  Port  number  below  will  be 
changed  when  the  packet  enters  your  LAN  (to  the  LAN 
Server/Client IP)
Type:  Select  the  port  number  protocol  type  (TCP,  UDP  or 
both).  If  you  are  not  sure,  leave  it  to  be  the  default  Both 
protocol.

3.6.2 Special Application
Some  applications  require  multiple  connections,  such  as 
Internet  gaming,  video  conferencing,  Internet  telephony 
and  others.  These  applications  cannot  work  when  Network 
Address  Translation  (NAT)  is  enabled.  If  you  need  to  run 
applications  that  require  multiple  connections,  specify  the 
port  associated  with  an  application  in  the  "Trigger  Port"  out 
going  port  field,  select  the  protocol  type  as  TCP  or  UDP, 
then enter the public ports incoming port associated with the 
trigger port to open them for inbound traffic.
