Ping 10.0.0.99...Reply from 10.0.0.102????

I'm pinging a pc via the command prompt and the reply from is 10.0.0.102 instead of the IP that I gave it to ping. Is that weird?

It's a little bit weird, but not unheard of.

Almost certainly has nothing to do with proxies, though (wrong layer).

The machine is literally right next to me. Current network setup for the house:

1. Comcast cable modem w/wireless router. Wireless radio turned off.
2. Airport Extreme Router #1 - Working as wireless router & DHCP.
3. Airport Extreme Router #2 - working as wireless signal extender only.

Basically Apple airport extreme #1 controls the entire network and is responsible for assigning IPs. This is because the Comcast router is terrible, it keep s dropping wifi signal.

N/M I figured it out when I posted the last post. Since the pc is connected to Comcast router via ethernet cable and the comcast router is not the DHCP server, the airport extreme #1 see anything connected to comcast router as 10.0.0.102 (ip address of comcast router). Or at least that's what I think.

Switching Off the Wireless on the Comcast Modem/Router does not switch off its Routing.

So you probably have a "Confused Network" with two Routers doing NAT.

The airport control apps should flag 1 error for double-nat ! Fix it by placing your airport into the DMZ or setup bridging on the cable modem/router!
