This is pretty common practice when purchasing bandwidth from retail providers..

Over the last 24-48 hours I have noticed that I am seeing my IP being mis-represented quite often as 203.98.50.27 which appears to be a new upstream proxy hop I have not seen before: traceroute to 203.98.50.27 (203.98.50.27), 30 hops max, 40 byte packets 1 121-73-24-1.cable.telstraclear.net (121.73.24.1) 18.037 ms 17.681 ms 17.413 ms 2 ae0-840.ie4.telstraclear.net (203.167.223.114) 12.952 ms 12.781 ms 12.475 ms 3 ge-1-2-0-843.ie1.telstraclear.net (218.101.61.105) 21.357 ms 20.910 ms 20.661 ms 4 203.98.50.27 (203.98.50.27) 24.332 ms 24.066 ms 23.950 ms I have noticed it preventing non http traffic flowing across port 80 (netcat to amazon cloud), as well as interfering with stun and various other bits and pieces, (incoming and outgoing connections to/from local webserver take longer than usual) Can anyone confirm similar behaviour who is on Telstra cable network, or have further details. Appears to be a netcache proxy. Proxy Server Details: 1.1 nc2 (NetCache NetApp/6.0.5P1) Kind regards -JoelW
