Hi.
In my office I have a DSC with EnvisaLink 3. I would like to connect it to my corporate LAN, but the problem is that I have to configure EnvisaLink to use a proxy server to be able to communicate with the Internet.
Since I can't find any information how/where to configur ethe proxy server, I would like to know if the EnvisaLink3 supports the use of internet proxy?
Tnx in advance for your help.

Re: EnvisaLink 3 and proxy support
Well, no, the Envisalink uses a proprietary protocol so there wouldn't be a proxy server out there that would support the protocol. You would need a proxy server that just forwarded at that IP level and that is what we call a gateway.
Proxies are just for well-known service like HTTP and FTP, not for other Internet based services.

Re: EnvisaLink 3 and proxy support
I'm admittedly being kind of nit-picky, here, but,...
Some systems include so-called "plug proxies" that simply ensure the TCP connections behave "sanely" or in the expected fashion. (Like a straight packet filter, they can also limit by source and destination IP address [range} and ports.)

Yes, you will generally see true application proxies only for well-known services and protocols.K-Man wrote:Proxies are just for well-known service like HTTP and FTP, not for other Internet based services.
