comment Understanding the static IP I just purchased
I have access to *nix boxes all over the country... but since I don't know any public IPs in my home network, I can't traceroute to them. (traceroute to 1.2.3.61 and 1.2.3.62 both end at 68.86.105.58 and 71.237.109.255 resp, without reaching my home network)

The comcast-provided cable modem has a coax in, and 4 "LAN" ports out. I now have my laptop on one of those (bypassing my home router). The cable modem is assigning me a 10/8 address (the router was giving me 192.168/16 addresses). Traceroute shows outbound traffic as hitting 10.1.10.1 (which is the DHCP-assigned gateway addr for my laptop) and then 73.252.30.1 (a comcast router somewhere )

I viewed business.comcast.com/smb/services/Internet/ipaddress and then called to request a static IP.

I think your edited scenario must be the correct one since an RFC1918 address assigned to my router would prevent my server inside the DMZ from being reached from the outside. I still don't understand why my externally-reported IP is that of the gateway, however.

This is a wonderful post with lots of detail, but it's all about NAT. I understand NAT perfectly well, I just don't understand which IPs are assigned where in my home network.

This is what I thought; something has me confused: whatismyip.com shows 1.2.3.62 (ie, the gateway IP). Doesn't this mean my ISP gateway is rewriting its IP addr in the outgoing packet? Doesn't that mean I can't route to my home network?

@Darius ipconfig/all shows a gateway of 192.168.2.1 (ie, a non-routable address), which doesn't help me. I want to know what my router's public IP is.

comment How can I change to the previous directory instead of going up?
@Randal: How is it shell-specific? It's a program.
