Upgrade Squid v2 to Squid v3

Hi

I have some troubling after upgrading Squid from version 2 to version 3. As I have read it is som changes to be made to the config, but i dont know what.

The old server has no iptables-rules and this is the working config:

http_port 8080 transparent

cache_dir ufs /var/spool/squid3 100 16 256
cache_mem 512 MB
refresh_pattern ^ftp:           1440    20%     10080
refresh_pattern ^gopher:        1440    0%      1440
refresh_pattern -i (/cgi-bin/|\?) 0     0%      0
refresh_pattern .               0       20%     4320

acl manager url_regex -i ^cache_object:// +i ^https?://[^/]+/squid-internal-mgr/

acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1

acl localnet src 10.0.0.0/8     # RFC 1918 possible internal network

acl SSL_ports port 443
acl Safe_ports port 80          # http
acl Safe_ports port 21          # ftp
acl Safe_ports port 443         # https
acl Safe_ports port 70          # gopher
acl Safe_ports port 210         # wais
acl Safe_ports port 1025-65535  # unregistered ports
acl Safe_ports port 280         # http-mgmt
acl Safe_ports port 488         # gss-http
acl Safe_ports port 591         # filemaker
acl Safe_ports port 777         # multiling http
acl CONNECT method CONNECT
acl fm dstdomain intranett.fm.no
acl nrk dstdomain tv.nrk.no
http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost
http_access allow localnet
always_direct allow fm
always_direct allow nrk
http_access deny all

I have tried this config but replaced

http_port 8080 transparent

with

http_port 9090
http_port 8080 intercept

But it is still not working. The traffic is getting from the client this way:
Client -> Checkpoint FW (HTTP_mapped rule, SRV_REDIRECT(80,10.235.16.2,8080)) -> Squid (10.235.16.2)

Any idea?
