I've tried the suggestions on both google and on this forum i can't seem to get Squid to allow external connections...Apologies this is on a headless Mybook world.

my lan information
current ip addressing 192.168.0.x
Squid box ip
Router Ip

Have tried playing with http_access flags without any luck any assistance is more than appreciated. apologies has been many many years since i setup a proxy

if any one could help would be much apperciated.

Using the below.
acl our_networks src
http_access allow our_networks

#Recommended minimum configuration:
acl all src
acl manager proto cache_object
acl localhost src
acl to_localhost dst
acl our_networks src
