Upstream proxy not working

hadi57

hi

my ISP request me to put proxy on my pc, due to some probles accessing hotmail, gmail, facebook etc…, so i tried:

1- use upstream proxy, (it runs excellent but for only 5 seconds, then squid stopped)

2- i tried one client pc and i fed the proxy into internet option > connection > lan settings > use proxy server, and in exceptions i put the pfsense gateway (what happen is i am not able to see the captive page any more, so i used another firefox together with internet explored but without the proxy so i can see the captive portal page every thing went fine. but:

my clients now must have 2 internet explorers, one to be able to open the captive portal page and browse non https sites, and the other to use to access hotmail, gmail, facebook, etc...

my setup is as follows:
proxy interface: lan
allow user on interface: checked
Transparency proxy: checked
Enabled logging: checked
remaining: default

upstream proxy:
Hostname: proxy number giving ISP
TCP port: giving by ISP
ICP port: blank
Username: blank
password: blank

cache managment:
hard disk cache size: 50000
Hard disk cache system: aufs
hard disk cache location: default
memory cache size: 512
memory object size: 0
minimum object size: 0
maximum object size: 400000
remaining= default

any body tried the upstream proxy server? if so please help me solve this problem

help really appreciated

thank you in advance
