Connecting to a remote server
Hi,

I have an interesting problem. I cannot connect to a personal server I set up. What's interesting is that I can connect to it from the LAN using its non-local IP address. However, I cannot seem to connect to it from anywhere else.

Here's how my server is set up:
My entire home has a single Ethernet cable that goes directly into our router. Every device in the house is connected to the router. My server is on a static (local) IP address. The router is configured to forward the necessary ports to my server. So, when I tested out my connection, I was able to connect to my server from another computer on the same local area network using my non-local IP address (the IP address assigned to my router by my ISP). However, when I try to connect to my IP address from a computer that is not on my LAN using my non-local IP address, I receive an error like this:
Code:
10061 - Connection refused
The server you are attempting to access has refused the connection with the gateway. This usually results from trying to connect to a service that is inactive on the server.

I can connect to my server from my LAN using the router's IP address, but I can't connect to it from outside of my LAN using the router's IP address. Does anyone know what I'm doing wrong? Could there be some sort of setting I missed that's necessary to make my router "public?"

multinet

MULTINET(8)						      System Manager's Manual						       MULTINET(8)

NAME

       multinet - Connect to a Multinet* DECnet over IP server

SYNOPSIS

       multinet [options] <local-decnet-addr> <remote-host>

DESCRIPTION

       This  utility  creates a tapX device and copies all the DECnet packets from that over IP to a remote Multinet* server. It provides a way to
       connect a Linux box to a remote VMS machine over an IP-only network. Using Linux routing it should be possible to connect  DECnet  networks
       over the internet using this technique.
       local-decnet-addr DECnet node address of the tapX interface. This need not be the same as the address used on other interfaces but it might
       be less confusing if it is.
       remote-host IP address or host name of the remote Multinet server. If you send a HUP signal to the process it will lookup this name  again,
       so you don't need to restart the server if the remote node changes its IP address.

       *Multinet is a product, and probably a trademark, of Process Software.
	      http://www.process.com and is available free for hobbyist use.
	      The protocol used here was reverse engineered by Mark Berryman and Christine Caulfield.

OPTIONS

       -v     Be verbose and dump packet contents to stderr

       -1     Advertise as a level 1 router

       -2     Advertise as a level 2 router (default)

       -D     Make  the tapX device into the default DECnet device. This will force all traffic to non-local nodes down the Multinet link.  IMPOR-
	      TANT: Due to a kernel bug you should not use this option unless you are using a Linux kernel version 2.6.17 or later.

       -p priority
	      Router priority. Default is 64

       -P port
	      Port to talk to Multinet on (default is 700). Ony change this if you know the Multinet server is listening on a different port

       -m MTU Maximum size of packets. (default 576)

       -t secs
	      Timeout for IP connections. If no traffic is seen on the IP connection after this time then the daemon will attempt to restart it.

       -H hello timer
	      How often HELLO messages are sent (default 60) in seconds.

EXAMPLES

	 multinet -1 -D 3.2 zarqon.tykepenguin.com
