How about WinGate proxy servers?
Yes, but you must configure a TCP mapping service (or mapped linked ) to the time server site. One set of example
steps to do this is:
Assuming your WinGate proxy server is called 'wingate',
1) Set up a mapped TCP connection in WinGate with the following mappings:
Accept connections on port: 37
Enable default mapping to: time-A.timefreq.bldrdoc.gov on port 13
2) Set up Atomtime98 as follows:
Route via HTTP proxy server: wingate
Port: 37
