PAC file and ASA

Hi eveyone,

I have PC which has proxy configured and i can access all the websites with it.

Traffic goes via firewall and websense.

Another PC with no proxy configured i can not access some websites.

FW logs shows when the connection is not made

Apr 22 2013 15:03:28: %ASA-4-507003: tcp flow from to outside:terminated by inspection engine, reason - inspector reset unconditionally.

Apr 22 2013 15:03:28: %ASA-6-302014: Teardown TCP connection 4984216 for outside:/443 to :/59557 duration 0:00:00 bytes 123 Flow closed by inspection
Apr 22 2013 15:03:28: %ASA-4-507003: tcp flow from /59557 to outside:/443 terminated by inspection engine, reason - inspector reset unconditionally.
Apr 22 2013 15:03:28: %ASA-5-304002: Access denied URL https://x.x.x.x/ SRC DEST on interface .

So need to know if connection is not made to those websites then traffic goes via firewall only?

it does not touch the websense?

When proxy is config on browser how hoes firewall handle the request then?

If someone can explain me traffic flow from PC to Websense please?

Thanks

Hello Mahesh,

So basically with the Proxy you can access any outside server but without the proxy you cannot right?

Can you share the show run policy-map

Hello,

No , I dont,

I said that I am definelty not a websense expert but I will check the reports/logs on the websense appliance and then filter based on your client ip address having issues
