PAP2T vs RT31P2

[usa2k]

My config (roughly) is:
Motorola SB5120 Cable modem -> Linksys WRT54GL (Tomato) -> Linksys RT31P2

That sounds like a sensible configuration.

OK. I can see your setting as below:
#1 comcast modem (correct?). The default gateway on the device is 172.20.0.1. Now leave the DHCP enable on this device.

#2 your RT. When you connect the RT to the #1 in any port. But you must connect the other end on RT into the <B>Internet</B> port.

#3 A XP machine that connects to the RT.

If you run the ipconfig /all on the XP, you should get something like this:
IP: 172.20.0.1XX
Subnet: 255.255.255.0
Gateway: 192.168.15.1
DNS: 192.168.15.1 <- I am not sure about this one. Did you assign this?

Now open a browser,and type: http://172.20.0.1XX, the one you got from the command ipconfig /all. You might try: http://172.20.0.1XX:8080 or http://172.20.0.1XX:9999, it depends on the port VOIPo sets for you.

See if you can access.

I've been following this thread and you have me confused. If I am missing something I apologize for "butting in."

Why would he be getting a 172.xx address off the LAN side of his WRT router to his (XP) computer. Unless he made changes the "normal" IP generated on the lan side would be in the private 192.168.x.xxx range. I've never seen a router (out of the box) generate a public IP on the LAN.

When I run IPCONFIG/ALL I get this (this is Win7):

• Connection-specific DNS Suffix . :
  Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller
  Physical Address. . . . . . . . . : 00-xx-xx-xx-5F-9F
  DHCP Enabled. . . . . . . . . . . : Yes
  Autoconfiguration Enabled . . . . : Yes
  IPv4 Address. . . . . . . . . . . : 192.168.1.20
  Subnet Mask . . . . . . . . . . . : 255.255.255.0
  Default Gateway . . . . . . . . . : 192.168.1.1

My Voipo device is getting 192.168.1.5 and to access it I use http://192.168.1.5
Again, if I am misunderstanding something I apologize.

172.16.0.0 - 172.31.0.0 are class B private networks. 192.168.x.x is class C and 10.0.0.0 is the Class A. All three are private subnets and are not routable on the internet.

Most of the routers are set to give a subnet in 192.168.x.x. I think the user must have changed it to the class B private address.

LAN on 172.31.125/24 here...

Yes, I realize that, but the thread read like "who's on first and what's on second" and I didn't see anywhere where he changed the router default (and have no idea WHY anyone does that on the LAN side as it makes no difference) but obviously he did. Also I now see he is plugging his laptop into the VOIPO device which gave him the 192 address which confused me as well. The thread had my head spinning with WRT RT WRT RT . I prefer "voipo device" and "WRT router" just for clarity (I did tech support training for an ISP and we preached clarity as the key with end users) .

Anyway, I should have kept my mouth, er, keyboard, shut.

I'm heading off to bed in a few minutes, so I can try this tomorrow. I will have to re-enable DHCP on the RT so the laptop gets an IP.

My config (roughly) is:
Motorola SB5120 Cable modem -> Linksys WRT54GL (Tomato) -> Linksys RT31P2

The cable modem assigns a public IP to the WRT. The WRT then assigns an internal IP (172.20.0.101) to the RT.

The LAN addresses on the RT are 192.168.15.x, so when enabling DHCP on the RT, the laptop gets a 192.168.15.x address (not 172.20.0.x address like you mentioned above). For DNS, I didn't assign to 192.168.15.1. I believe that's the default when NAT is enabled. When a laptop connects wirelessly to the RT, the default gateway and DNS are 172.20.0.1 (the WRT IP).

I have enabled remote administration on the RT, so I can access it via a laptop with a 172.20.0.x address.

Is there anything I didn't address?

Now try this:

type this in your browser: http://192.168.15.1. If it asks for userID and password, use this:
UserId = admin
Password = admin

Can you access?

If I am using a laptop connected to the WRT54G, I need to use http://172.20.0.101:<port> to access the RT's GUI (remote administration I guess is what it's called). If I had a laptop connected to the RT (which I will never do since it's not wireless), I'm sure that the IP you provided will work.

The admin/admin won't work (any longer). I changed the password.

My setup is done (for now). I put the RT in the DMZ for it to stay online (port range forwarding wasn't enough apparently).

A lot of (my) confusion was because of my boneheadedness of reseting the RT early in the process, which wiped out the provisioning string required for VOIPo. I think I had the setup done right early on, but it wasn't getting Phone 1 lit, so I kept changing settings hoping it would work, which resulted in lots of questions here.
