Squid - Dynamics CRM client blocked

rich2010

I've configured Squid to work with Pfsense 1.2.3 Release transparently. Everything is fine apart from when trying to use MS Dynamics CRM client for Outlook which gets blocked. If you go to the URL that the client is trying to access in browser, it works fine. Here is my Squid conf :

/usr/local/etc/squid/squid.conf

Do not edit manually !

http_port 192.168.1.1:3128
http_port 127.0.0.1:80 transparent
icp_port 0

pid_filename /var/run/squid.pid
cache_effective_user proxy
cache_effective_group proxy
error_directory /usr/local/etc/squid/errors/English
icon_directory /usr/local/etc/squid/icons
visible_hostname localhost
cache_mgr admin@localhost
access_log /dev/null
cache_log /var/squid/log/cache.log
cache_store_log none
shutdown_lifetime 3 seconds

Allow local network(s) on interface(s)

acl localnet src 192.168.1.0/255.255.255.0
uri_whitespace strip

cache_mem 8 MB
maximum_object_size_in_memory 32 KB
memory_replacement_policy heap GDSF
cache_replacement_policy heap LFUDA
cache_dir aufs /var/squid/cache 100 16 256
minimum_object_size 0 KB
maximum_object_size 10 KB
offline_mode off

No redirector configured

Setup some default acls

acl all src 0.0.0.0/0.0.0.0
acl localhost src 127.0.0.1/255.255.255.255
acl safeports port 21 70 80 210 280 443 488 563 591 631 777 901 3128 1025-65535
acl sslports port 443 563
acl manager proto cache_object
acl purge method PURGE
acl connect method CONNECT
acl dynamic urlpath_regex cgi-bin ?
cache deny dynamic
http_access allow manager localhost

http_access deny manager
http_access allow purge localhost
http_access deny purge
http_access deny !safeports
http_access deny CONNECT !sslports

Always allow localhost connections

http_access allow localhost

request_body_max_size 0 KB
reply_body_max_size 0 allow all
delay_pools 1
delay_class 1 2
delay_parameters 1 -1/-1 -1/-1
delay_initial_bucket_level 100
delay_access 1 allow all

Allow local network(s) on interface(s)

http_access allow localnet

Custom options

redirect_program /usr/local/bin/squidGuard -c /usr/local/etc/squidGuard/squidGuard.conf
redirector_bypass on
redirect_children 3

Default block all to be sure

http_access deny all

As I said, if I go to the URL that the client is trying to access in a browser (i.e http://crm.host.com/MSCRMServices/) you can get through to the login. The Outlook client always fails in Outlook until I disable the transparent proxy in PfSense.

Any ideas ?

Thanks

A reboot of Pfsense fixed this

sorry, this actually started again - if anyone has any ideas on what it could be please post up

Thanks
