Limited connectivity on lan

Were trying to configure a cisco pix 510 we recently aquired, but when we hook it up to our lan we get a limited or no connecty message, we have no idea why, DHCP is enabled, and we get an IP in the status. please help

Did you configure the firewall to allow data to transmit. I am not a Cisco wizard but if everything was working prior to installing the firewall then your firewall is not configured properly.

Do you or anyone else involved have Cisco expreience?

From my understanding, you just don't hook it up and go.

we aquired them used from a company that went bankrupt, still configured the way they had them, it has a console port on the back, which from my understanding is that u run a console cable(similar to cat 5) into a serail port converter. And you can configure it from cmd. the other way is through IE. much like other firewalls/routers, you can configure it over an https connection. but we cant seem to find out what the ip its set on is.

correction, its a pix 501, its basicaly a router

its got a standard cmos battery on the inside, u think if i remove it for an extended period it will go back to default?

You'll need to follow the "password recovery procedure" below.

After rebooting, login with the enable password, then at the command line run:
write erase
reload

Once it reloads, it'll be set to factory defaults.

That did it, thanks

If it happens again check the ethernet cable you are using.
