PIX not forwarding Traffic

[thanzeer123]

Dear all,

I am facing a strange problem with my PIX firewall. On every weekend my PIX firewall stops forwarding traffic from the proxy server, all the other traffic passes through and doesnt have any problem. The proxy server traffic is getting stopped. The translation table doesnt show any connection as well. The proxy server address is PAT translated. we are running cisco PIX 6.2. All inputs are appreciated.

What is the exact version of pix code (i.e., 6.2.1, 6.2.2) and what model pix you are using? Do you have two pix units in failover mode, or just one unit?

How do you fix the problem? And how do you notice it?

How is the other traffic getting translated - NAT/PAT?

I will provide more information on this.

Exact version 6.2(2).

Fix - need to restart the PIX.

Other traffic that PIX forwards has both NAT and PAT.

One other thing I'd like to know is what make and version is the proxy server. If you can, find out if the pix's interface speed and duplex settings are hard-coded in the config and the switch port that they connect to, or if auto negotiate is being used.

I recommend that the values be hard-coded, yet your problem happens over the weekend. I would expect that the majority of the proxy server traffic happens during the weekday business hours, unless there is a large volume of traffic passing thru the proxy at non-business hours.
