First, take a look here: http://forums.bitcomet.com/index.php?showt...ost&p=45711

Your router has two sides. THere's a WAN side that connects to your modem and ISP, and gets an assigned address in the 88.55.xxx.xxx range. You have to set that side up the way your provider instructs you too, and leave it alone.

Then there's a LAN side. Your computer connects to this side. You pretty much control how this side gets set up.
On this side, the router has a completely different address, valid only on this lan, and only in terms of devices connected to that side of it.

Now, you get confusing. There are two commonly-used address blocks which are reserved for LANs, and your router should probably use one or the other of them. But you say instead that your router has "an address example" of 00.00.00.00

That's weird. It makes me think somebody's been mucking around with it and didn't know what they were doing. Is that what the address really is? If so, is it in the manual that way?

If not, then you need to find out how to reset the thing to its factory defaults. This is usually a little bit difficult to do, intentionally so because it shouldn't be easy to do by accident. you've usually got to stick a pin in a little hole and depress a button in there for ten seconds, or something like that.

It should reset to the class C reserved LAN block, 192.168.xx.xxx, but it might use the class B reserved LAN block, 10.xxx.xxx.xxx No big deal if it does, this just determines how many different devices can be on the lan. For most people, the first block gives them 256 x 256 = 65,536 devices. (That's usually enough.)

One address needs to be used by the router itself on the LAN side. Let's say that is 192.168.1.1, and make it so if it isn't. (This isn't the lowest address in the pool, the lowest one is 192.168.0.0 but the zeroes make people nervous.)

Its netmask defines the valid range for your network, and it's usually 255.255.255.0 Combine that netmask with your base IP address, and what it means is that the first three octets are fixed at 192.168.1, while the last octet can have any value from 0 to 255 - you can have 256 different devices on this LAN when its set up this way, and this is usually far more than you actually need.

Your computer will take up another of those addresses, and you've still got plenty left over.

The router takes all of the computer's requests and reframes them as if they were the router's requests. So when you visit WhatsMyIP.com, it is not your computer that's asking. It's the router that's asking at some computer's behest, and what gets reported is the WAN side IP address that the router got from your ISP via the modem. (If you have a second computer hooked to that router and it asked WhatsMyIP.com, it will be told it has the same address as the first computer, which would ostensibly be impossible - can't have two devices on the network with the same address.)

If you want to see your computer's IP address on the LAN, use the IPCONFIG command from the DOS shell. That address is not visible to anyone not on your LAN, and neither is your computer itself. All the outside world can see is the WAN side of the router. IPCONFIG will tell you you have a LAN-range address, something like 192.168.1.xxx

Ports now, you need one and only one port. It is the same port that you choose as a listen port and set up that way in your BitComet preferences. All of these other ports, this A through H nonsense, you can forget about. Compound misunderstandings. You just need the one port. You use it throughout.

I usually just tell 'em to use port 65432, because I said so, don't bother me, kid. This is to take care of the ditherers who go into fits if you tell them to just pick a port.

thanks for the help...that's sorta what i figured.

i've found an extra conundrum so i'll be more specific from the beginning.

SETTINGS:

?Software Firewall is off
?Stateful Packet Inspection firewall on the router is off
?my router address is 10.0.0.1
?my LAN address is 10.0.0.2
?my WAN (Modem) address is 83.XX.YY.ZZZ
?Default DMZ server is enabled on the router and set to 10.0.0.2
?Router is enabled as a DHCP server

?I deleted all the port forwarding (i previously mentioned) and left one only port 65432 TCP/UDP forwarded
?listen port in BC is 65432
?No port triggering is enabled on the router

-----------------------------------------------------------

under the last environment the router address space was 192.168.1.1 to 192.168.1.254
and this computers IP used to be 192.168.1.3

but when I reinstalled everything under this new network environment
the address space is 10.0.0.1 to 10.0.0.254
and this computers IP is now 10.0.0.2 as said above

---------------------------------------------------------

HERE'S THE INTERESTING SETTINGS I FOUND ON THE ROUTER SETTINGS:

Internet Port:
MAC Address AA.BB.CC.DD.EE.FF
IP Address 192.168.1.3

LAN Port:
MAC Address AA.BB.CC.DD.EE.FF
IP Address 10.0.0.1
DHCP On

i reckon this could be the cause of the listen port being blocked???

and i tried to port foward for 192.168.1.3 but obviously i'm not
allowed - only 10.0.0.XX addresses can have ports forwarded.

i also tried port triggering on 65432 but no dice.

-----------------------

NEXT

in the router setup my IP Address and DNS are got dynamically from the ISP

I ran "ipconfig/all" this is what is said:

?Gateway,DHCP server and DNS server are all 10.0.0.1
?IPv4 address 10.0.0.2 (preferred)

so next i tried to set the IP and DNS in the router myself to these.
it didn't work so i set it back to "get dynamically from the ISP"

now i ran "ipconfig/all" again and it says now:

?Gateway,DHCP server and DNS server are all 10.0.0.1
?IPv4 address 10.0.0.3 (preferred) .... (presumably this changed due the IP conflict from setting it myself)

------------------------------

i'm sure the problem lies between the IPs and this 192.168.... and 10.0.0..... issue???

if you need any more info please ask...

there must be an easy answer, please help!!!!

also, i'm not sure if it matters but uPNP is off

i'm sure there's an easy answer to this i'm overlooking,

thanks for the help

Hmm. I'm not clear on how that got set that way, but let's go with the flow here.

So you're using the 10.xxx.xxx.xxx block, which is just fine. Quite a few routers default to this. The only significant difference is that you have a possible 256 x 256 x 256 = 16,777,216 possible device addresses on that block. But you'll probably never need more than two or three of them. So this is cool.

Your default gateway means "where do I go if I can't find what you want around here?", and for you and most people, there's only one gateway -- your network card and whatever is on the other end of it. So in your case, it's the LAN address of the router. That's your default and only gateway. DNS searches also get passed to the router, which in turn, passes those searches to whatever the WAN side has been told to use for the purpose. But that doesn't affect settings on the LAN side. ANyway, default gateway and preferred DNS servers are the same.

As I said on the other thread, addresses can be requested via DHCP. This is how the WAN side of your router gets its 83.xxx.xxx.xxx address - by asking your ISP for an assignment. That's fine.

But it's no good for port-forwarding. (port triggering is something else and doesn't apply here.) Look at your router and read your manual. If it requires an IP address for a forwarding/virtual server rule, then you cannot use a dynamic address from DHCP for this purpose, and must set a static address as stated. If you do not then it will be a matter of pure luck if you happen to get the right address with the open port on it.

Now I'm very uncertain what you mean by the phrase, "on the router settings". Do you mean the manual? Or from the control interface? Or exactly what do you mean? From what you say it's trying to use both reserved blocks, which is going to cause a lot of confusion here. What exactly are you referring to here? In detail. You speak of "the internet port" on the class C block, and "the lan port" on the class B block, where they probably ought to be one and the same interchangeable port, unless you have two NIC's, which would be the first mention of THAT, and a serious additional complication. Very much confusion, very much doubt here. You need to go into great detail about what you're talking about, since I can't see it for myself.

I can't advise you how to proceed until this is cleared up.

not to intrude stevy but all i did was call my isp provider and had them turn off my windows firewall and shit.....greenlight to go!! i turned it off from my end and nothing, but when they turned it off, everything. hope this helps. i,like you,was stumped on this for a long time.
