Cisco Pix 501 random connectivity

Hello. I am having some troubles with my CISCO PIX 501 configuration.

Since a few month ago I started to get random disconnections on my network (from inside to outside). The machines can ping the DC or the Pix but cannot surf over the internet. The only way to make them to go outside is a Pix restart.

 

My configuration is the following:

Do you have any advice? I am not getting what is wrong with my configuration.

My DC is 192.168.100.2 and the network mask is 255.255.255.0

The network configuration is set up to set the Gateway IP to 192.168.100.1 (which is the PIX 501).

I have around 50+ peers on the internal network.

Any help is apprecciate.

Hello Paul, how can I check it?

The number of the peers of my network is not stable everyday (can vary depending from the number of the employees at office that day and the number of personal devices connected to the network...).

Is it limited to 50 hosts?

How can I raise this limit?

Thanks.

HelloYou need to purchase

Hello

You need to purchase this of a cisco reseller or cisco direct but I am afraid cisco pix are now EOL so you may have to upgrade your PIX FW to an ASA FW or if that isn't palpable and finances are tight maybe remove the pix altogether and depending on your existing routers male/model apply IOS security to the router.
