Hmm...I don't think this is going to work if you want to use the browser-based viewer. The problem is there are *two* ports involved for that, one to serve up the viewer and one to make the VNC connection, and only one of them can be port 80. ;) If you use the stand-alone viewer it should work okay, though.

When I type in "http://<ip address>" into my browser, I get the message "RFB 003.003" message. I have tried forwarding port 80 to port 5900 and 5800 to the box I'm trying to access, but get the RFB message either way. What did I do wrong that I'm getting that RFB message? I'm unable to "telnet <ip address> 80" from a command prompt either. On a side note, I am testing this on two PCs here at work. With the display number set to 59716 on one of them, I get the same RFB message when trying to access it from a browser. While looking at the PC with the 59716 display, and pressing "reload" on my browser pointed to "http://<ip address>", I can see the screen flicker. If I telnet into the PC with the 59716 display number and I get the RFB message. Not sure if that helps any.

Basically the large positive number 'wraps around' to a negative number due to how it's handled internally. Bit of a hack but several people have suggested it works. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, February 22, 2002 11:00 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Connecting from work to home Thanks for that information. However, when I try to type in "-5820" in my display number field, it won't accept the "-". Is this correct? How can I set VNC to run on port 80 if it won't take the negative number?

Sorry for the late reply. Most firewalls that a company would use come "out of box" with only a handful of external services reachable. That is, the firewalls will allow anyone to connect to FTP, Telnet, HTTP, HTTPS and SMTP. That's about it. For example, an "ICSA approved" firewall: http://www.icsalabs.com/html/communities/firewalls/certification/criteria/cr iteria_3.0a.shtml Anyhow. As you'll noticed in the above, the actual *content* of the data connection is not a requirement for most firewall ceritifications, nor is content-based filtering a capability of most firewalls, either. So, I'm betting that the firewall at your work allows anyone to connect to any server that's listening on the default ports of FTP, Telnet, etc, etc. My suggestion, then, is to trick your workplace firewall by changing the mapping of your LinkSys box. So, have port-80 (which is the default for HTTP servers) on the outside of your LinkSys box go to port 5900 of your home-LAN VNC machine. Then, from work, "telnet a.b.c.d 80" and see if it connects. If it does, then you can get the VNC viewer to connect as well. I'm pretty sure your LinkSys box lets you map port-A to port-B (some lower-end boxes won't). Good luck! -Scott > Thanks for everyone's help. I had someone else try at a different company > to get to the home PC and they were able to get connected via the Java > viewer.
