This is my setup
I'm trying to SSH into a diferent subnet on my local net, I can SSH from PC 2 to PC 1 but not the other way around. router has DHCP enabled.

You need to configure a firewall rule on the router to allow the ingress traffic. I suggest you configure port forwarding. You can follow this link[1] for a detailed guide.

The website is showing my correct internal LAN IP address.
https://www.whatismyip.com/
It does not work in Safari.
I do not suspect this is an XKCD #628 attack. How is this website implementing this?
This is because of WebRTC feature.WebRTC feature will leak your IP address even if you are behind a proxy server or using a VPN service.

I have a Windows Server 2012 R2 Standard using a D-Link router. I want to Configure it using Static IP Addresses.
Try to turn off the firewall and ping to test the response.
If that does work, then re-enable the firewall and allow ping.

Sorry for the language mistakes I've made. I don't have static IP to be accessible from outside world so I want to run a dead simple http server on my dynamic IP which I get from DHCP of my local provider. How can I make it?
I use Ubuntu and similar with nginx. I tried something like this:
~path/to/index.html$ python -m SimpleHTTPServer 80 #of course nothing
Yes you can,
But you must use a proxy like:
DYN DNS
NO-IP
etc.
These sites gives you a link static IP and forwards it to your dynamic IP address.
The IP provider needs to be updated with your current IP.
This is done either via a service on your computer, or via your router (if it supports Dynamic DNS it).
The conclusion is that your current IP address must somehow be connected to a DNS (like www.something.org).

I'm working with SVN server to develop SW.
I have nothing but single dummy hub(5 port).
What I want to do is sharing source FILE on the SVN server so that all developers can work together.
please check my plan to do this...
Allocating IP address to all client...
client1 : 172.20.20.11
client2 : 172.20.20.12
client3 : 172.20.20.13
client4 : 172.20.20.14
SVN server : 172.20.20.100
GW : 172.20.20.1
NETMASK : 255.255.255.0
I'm not sure for the GW ans NETMASK config....
Is this possible?
Netmask is fine, or you could use 255.255.0.0 (and a few others; doesn't matter so long as every machine has the same configuration).
Gateway doesn't matter since you don't have internet access anyhow, set it to 172.20.20.whatever.

Server has 2 IP addresses. How can I route 2 servers with 2 different ports to the 2 IPs on the same port [closed]

I want to route:
127.0.0.1:25565 <-> 40.39.210.1:25565
127.0.0.1:25564 <-> 40.39.210.40:25565
Note that the 2 internal IPs are the same, but the ports are different, and the 2 external IPs are different, but the ports are the same.
Is this possible? I was looking at iptables, but I have absolutely no idea how to use it.
Just to capture the comment as an answer...
Would it not be easier to get the two different servers to bind to the appropriate IP on the appropriate port, or is there something that is preventing this from happening?
If I look on the minecraft wiki here, I see that it is possible to set the server-ip property to make this happen.
