your modem has a pretty nice manual , if you google it, you will find it under "manual-1070.pdf"
anyway, ok, to correctly forwarded the ports required for FAF , you need to ensure two things:
ensure that your computer local IP does not ever change
add a routing rule of UDP 6112 to your local computer IP
FIRST forward the port
access your router, login
(1) go to TOP menu Interface Setup
you have there the ATM VC, then you have the PVC's summary button, press it
check what PVC you have the PPoE connection, default is PVC1
(2) go to TOP menu Interface Setup -> LAN :
I suposed your DHCP is Enabled, and your Starting IP address is : 192.168.1.2
check the value of IP Pool Count, default is 32, note this number, you will need it
(3) go to TOP menu Advanced Setup -> NAT :
Choose the PVCx , where x is the one that had your PPoE connection in step 1 , select it
Click on Virtual Server
select protocol UDP
Start port number : 6112
End port number : 6112
Local IP address :
from the DHCP starting address we have 192.168.1.2 (use the value you read in your router above)
from the pool count we have 32 (use the value you read in your router above)
so its 192.168.1.35, so lets give it : 192.168.1.40
press save
Now your router is configured
SECOND: for your computer local IP never change
You now need to ensure that your computer IP is 192.168.1.40
to do that, go to Control Panel -> Network and Sharing -> Adapter Settings
double clic on the adapter your are using
click properties
WARNING after this step is made you will loose internet connectivity for a second or two
go to IP Version 4 Protocol, double click
select Use the following IP address :
IP : 192.168.1.40
Mask : 255.255.255.0
Gateway : 162.168.1.1 (this will be your router address, change it according)
DNS, if it does not allow you to use automatic, you can use or the router gateway address or, something like OpenDNS:
Server: 208.67.222.222
alt. server : 208.67.220.220
press OK, wait a bit, and you are done
have fun
NOTE: if you move your computer to another location, you might want to go back on your adapter settings, so just take a note of what you did there, and how to go back
