>> Tests: >> A) set a PC to x.x.x.104 using X-cable connect directly to proxyEXT external NIC - configure Firefox to x.x.x.103:3128 - Works >> B) from home - ping x.x.x.103 - Works >> C) from home - VNC into proxyEXT - Works >> D) tracert to x.x.x.103 - Works 17 hops >> E) from home - configure web browser to x.x.x.103:3128 - not working >> >> >> Test E) above. In Firefox I get a general error telling me the server took too long to respond. IE gives the DNS error page. >> >> These errors in E)above can be reproduced by configuring the web browser to a non-existent proxy. e.g. x.x.x.104:3128 > Thanks >step 1) is port 3128 open on the router? ie telnet x.x.x.103 3128 Unable to test as yet - Telnet not installed. > >step 2) is the router actually forwarding traffic from that port to >proxtEXT? wireshark/tcpdump will show this. I have no access to the router - it's ISP maintained - will forward your checks though. > >step 3) is squid proxy listening on pubic-facing IP (10.1.1.61) or >wildcard IP (0.0.0.0) at that port? netstat -antp Yes, netstat proved that it's listening on x.x.x.103 3128, and see test A above.
