PIX not working well


I have a company that complaines about unsteady connection to internet/pop3. Please look at config and tell me if you can see some error in config! The ISP supplier is working on the issue too but the old fw do not show any unstable connection to internet sp i guess it?s the pix. One user can listen to webradio without any interuptions?!

Thanks in advance!

Re: PIX not working well

You might be encountering the following:

Try (in configuration mode) enabling:

service resetinbound

Let me know if this resolves your problem, if it does please rate post.


Re: PIX not working well


I see two problems:

1. Check the interfaces for errors (sh int) as the statemens below might have a mismatch with the other end (duplex/speed)

interface ethernet0 10baset

interface ethernet1 100full

2. Overload (LAN and VPN clients) and static (web server) to the same public IP (interface IP) is also problematic. You should have another Public IP from your ISP for www server. That will improve performance.

Please rate if this helped.
