При попытке с клиента через проксю открыть любой сайт имя сайте обрезается.
То есть вместо http://any.site.ru/anyPage.html в сквид попадает только /anyPage.html

Если прописать адрес прокси в браузере все работает нормально.
Сквид собран с параметром enable_PF

Со всем этим богатством столкнулся первый раз, гуглить и читать форумы пробовал - ответа найти не смог. Надеюсь хоть здесь кто-нибудь сможет помочь.

ЗЫ PF offers a rdr-to option. However this not supported with any Squid. Use divert-to instead.

ОС freeBSD. Для нее в мане ( http://wiki.squid-cache.org/ConfigExamples/Intercept/FreeBsd... ) написано по-другому:

#set skip on $int_if << These lines commented out
#set skip on $wi_if

# redirect only IPv4 web traffic to squid
rdr pass inet proto tcp from 192.168.231.0/24 to any port 80 -> 192.168.231.1 port 3129

block in
pass in quick on $int_if
pass in quick on $wi_if
pass out keep state

Заворачивать нужно именно в 3129, см. внимательней
