comment Muxing private streams into/from MP4 and MPEG2TS with ffmpeg
Thanks for the reply, @slhck. After some research, I believe that I would have to write a codec for ffmpeg to handle a new media type; this is some work, but doable. But MP4v2 provides a nice api for MP4 files and I've decided to use that instead (for the MP4 piece of this project).

comment ssh port-forwarding with GatewayPorts = no
You can ssh from Y to X because (as noted in the question), X has a private IP. This means a reverse tunnel is required.

comment Converting my home network to accommodate a server with static IP
I'm running more than a web server; I have sshd and smtp servers too. I can log into my home network from anywhere via ssh giving me access to home devices (eg, home security cams). Plus, it's fun.

comment Converting my home network to accommodate a server with static IP
I don't want to use DHCP because if the IP address changes, my forwarding will break; so yes, I assigned it a static IP outside the DHCP pool and forwarded port 80. And to answer your question: I'm setting up a web server in my home so I don't rely on hosting services.

comment Can't source IP == destination IP for public IPs in home network?
@user142485 My setup, problem, and its solution are all well-described by wiki.mikrotik.com/wiki/Hairpin_NAT

comment Can't source IP == destination IP for public IPs in home network?
My router is a Comcast Business Class cable modem (that has a simple router built-in). I looked up Hairpin NAT and it appears to describe exactly my problem, so thanks very much for pointing me there. I will stick with dnsmasq given your point that it saves traffic through the router (and I can point all hosts in my network to my own name server, so this works for me!).

@user142485 10.*.*.*/8 is a RFC1918 address range. You can set the mask to anything between 8 and 30 for a LAN, depending on how many hosts you have. (tools.ietf.org/html/rfc1918)

@Luke I fixed the problem I had, but I'm posting here with a question that I don't have the answer for.

@SeanC. You're absolutely correct: the cable modem is acting as a DHCP server and router, and it does have a web interface. I'm going to work on seeing if it allows bridging of my internal devices (aka a DMZ) and take my home router out of the picture for now. In any case, your answers/suggestions have been invaluable; many thanks.

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)

comment Understanding the static IP I just purchased
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.

comment Understanding the static IP I just purchased
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.

comment Understanding the static IP I just purchased
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.

comment Understanding the static IP I just purchased
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?

comment Understanding the static IP I just purchased
@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.
