PIX 501 and 10 user license

I am looking at purchasing the PIX 501 with 10 user licenses. The product manual says:

The Cisco PIX 501 Firewall 10-user license supports up to 10 concurrent source IP addresses from your internal network to traverse through the PIX 501. The integrated DHCP server supports up to 32 DHCP leases.

If I run a web server for outside/inside will my connections be limited? Or is it just inside/out connections that have limits?

Only translations are counted. The static web server will only count as 1-user toward the license, no matter how many connections inbound come to it. This leaves you with 9 remaining available connections.

Hope this helps,

Re: PIX 501 and 10 user license

We have two PIX 501 one is in front of a 10-user LAN with an Exchange server on the protected side and use NAT and have opened port 25 through the PIX. The Exchange server opened five connections during the two hours it was in service. Only five of the 10 LAN user had Internet access. We tried to modify the default TIMEOUT settings but still had users with limited Internet access.

We found that the 10 user license was for ANY 10 connections through the PIX, it didn't matter whether the connections were inbound or outbound. If it passed through the PIX it counted. I wouldn't use this to protect a very active web/e-mail server.

We had to order the 50-user license upgrade. This PIX 501 is also the termination of a 3DES VPN. I'll be monitoring the CPU load.

Re: PIX 501 and 10 user license

The limit is on the 10 concurrent source IP addresses from your internal network , which means if you are running a web server it's going to use 1 ip all the time from the limitation.

but i think you need to notice to the two following facts :

1. the pix refresh the ip table (as a ip connection exery 30 sec)

2. the licese is for 10 ip addresses but the tcp Concurrent connections are 3500 , so you are going to be limited to a connection to your web server also.

i suggest that you need to use a pix 515 with a DMZ for your web server.

good luck

The 10 user license will only limit your outgoing connections. For connections from internet to your web server through the PIX, no license limitation.
