Hello,

I am trying to connect my home lab to the internet, I got this ATT uverse box that has everything integrated (Wireless, switch, modem).

Here is my lab set up, I am working from host in blue :)



I am able to ping from HQ to the ATT box (192.168.1.254) but I cannot ping anywhere in the internet.

Here is my running config from HQ

    I did some more research and I found this forum (Re: U-verse for BUSINESS? : 2Wire 3600HGV bridge m... - AT&T Community Support) with how to "bridge" the ATT box. It worked for me I know have the public IP address in my outgoing interface. I have set up NAT (I thought that the ATT box would have done for me, but apparently not). I still haven't find out why I cannot ping from computer to Att box (192.168.1.254). I don't see any routing problem do you?

    Thanks.

    Sleepy here, so perhaps I missed something, but the first thing that jumps out--
    ip route 0.0.0.0 0.0.0.0 FastEthernet0/0


    You used a lazy static route. Your cheap router may not support proxy arp. Try using a normal static route. You know, the kind where you specify the default gateway's IP address. Even if this is not the root problem, fix this so you're not proxy-arp'ing every dang address on the Internet.

    Also, you don't mention configuring your ATT box to know how to route and NAT for the 192.168.19.x range. Without those, you won't have much luck pinging Internet websites.

    I'd also change the speed/duplex from your HQ router to the uverse router, I've had problems with setting connections up using auto. Like NetworkVeteran said, without a route and NAT setup, you don't have much luck.

    For the subnet between ATT and HQ, are you sure it is /30? cuz you are also runing DHCP to get .72

    Also, I don't think you are advertising 192.168.1.0 in RIP

    Assuming ATT is runing NAT,

    just point your default route to .1.254 instead of the interface

    Probably need to create a nat pool on your HQ router, the create a nat overload rule for that sinigle address.
    set your default gateway on the hq pointing to your AT router and see if you can ping 4.2.2.2, do this is before you start with the rest of the
    network, first job is to get HQ working.

    Nice catch, I caught a statement like that yesterday on my 1841, wasn't able to login to it and got an "Low Memory Try Again Later" message when consoled in.

    Bounced it, logged in and saw the default route directed to the interface. Ugh!
    Modularity and Design Simplicity:

    Think of the 2:00 a.m. test—if you were awakened in the
    middle of the night because of a network problem and had to figure out the
    traffic flows in your network while you were half asleep, could you do it?
