Application is not working while going through Ironport S370

[ranjith.kanisan]

Hi,

We have deployed the Ironport as wccp trasperant mode and using software version is 7.1.3.

We are configured one application url in Allowed custom url categories, but we are not able to access the application when its traffic is flowing through the ironport . After we created the bypass policy for that url application is responding properly for the client request. When we are doing the policy trace(all the time, with or without bypass policy) for the url we are getting ERR GATEWAY message. Please find the below mentioned policy trace output.

User Information

User name: None

Group Membersip: None

User Agent: mozilla 4.0

Custom url category : Allowed

Policy match

Iron port data security policy : None

Decryption policy: None

Routing policy : Global routing policy

Identity policy: No Authentication

Access policy: No Authentication policy

Final Result

Request Blocked

Details: ERR GATEWAY

Trace session complete

Kindly suggest why this error is happening ? and How can i use the application through proxy with out doing the bypass settings.

Thanks in Advance

Regards,

Ranjith

Hi Ranjith,

An ERR_GATEWAY would imply that the application is being resolved but is not reachable, if it's using non-standard ports you may want to check your firewall.

Thanks

Are you using L4TM? If so please check your L4TM logs for the domain you are trying to access.  ERR_GATEWAY can indicate L4TM is blocking the website.
