Connecting to Vassal Server Through a Web Proxy

Winged_Human · December 17, 2009, 4:55am

Hello guys and gals,
Currently I have a problem connecting to the vassal servers while at work. (NO comments from the peanut gallery, I work overnights with long periods of inactivity… ) Either Way, the problem I’m having “I believe” is that I currently sit behind a web proxy. The network has been setup to NOT allow any type of port 80 (http) traffic unless it originates from the proxy. Now I know it works fine when I’m at home (not going through the proxy). So I need help in figuring out one of two things.

how to get the Vassal traffic to route to the internet through the proxy (I’ve tried adjusting the proxy settings in Java but that doesn’t seem to help any)
Modify Vassal to use a different port to reach the servers.

Just as an FYI I will attack a log file from what happens when I attempt to reach the servers from inside my network.

Dell D620
XP Pro SP3
Dual Core 2GHZ
2GB
32MB onboard
Vassal version. 3.1.12
Java6 Update 7

When I attempt to “Join a game” online I get a "Network Communication error, and a log that looks like this:

VASSAL isn’t picking up your system’s proxy information. Try this:

Create a file called VASSAL.l4j.ini in the same directory where VASSAL.exe
is. Put the following line in it

-Djava.net.useSystemProxies=true

and then start VASSAL and try to connect. If that doesn’t work, try
putting these two lines in the VASSAL.l4j.ini:

-Dhttp.proxyHost=nameofyourproxy
-Dhttp.proxyPort=80

where you replace “nameofyourproxy” with the name of your proxy.

Please let us know whether either of these works, and if so, which one.

Hey mate,
Thanks for the info, unfortunately neither of these worked.

Currently here is the info in my VASSAL.l4j.ini file:

-Djava.net.useSystemProxies=true
-Dhttp.proxyHost=172.31.60.75
-Dhttp.proxyPort=8080

I tried port 80 as well as port 8080 (because 8080 is the port we use to connect to the proxy server.

Is there a way to pass username/password info in this file as well?

uckelman · December 19, 2009, 3:00pm

Thus spake “Winged_Human”:

Try adding these:

-Dhttp.proxyUser=username
-Dhttp.proxyPassword=password

Does that work?

Unfortunately that didn’t work either, regardless of which port I used.

dancarmon · June 2, 2014, 8:55am

Worked like a charm.
Thanks!

My VASSAL.l4j.ini file says the following (I’ve placed *** for security purposes. My file has the full address name and port #, without ***)

-Djava.net.useSystemProxies=true
-Dhttp.proxyHost=proxy..intel.***
-Dhttp.proxyPort=9**
