PIX 501 Moving off server DHCP onto PIX DHCP

I'm sure this is deceptively simple but I couldn't find a good Google answer on it.

I no longer want to use a server as the DHCP and just use the PIX DHCP.  I can go into the PIX and enable DHCP and assign an address pool then disconnect the server from the network.  From there I can ipconfig /renew and ping other computers on the network.  So I believe that to be a sign that things are working on the DHCP side.

The issue is that I cannot access the internet.  So I'm assuming somewhere in the PIX it is forwarding requests onto the old DHCP and therefore nothing is getting internet.  I could be wrong but, I don't have much experience with Cisco routers and interfaces.  That's why I posted in 'Getting Started'.

A second question, because we have multiple IP addresses and would like to upgrade the router, what would you suggest to replace a PIX 501 with a 15 person network?

Re: PIX 501 Moving off server DHCP onto PIX DHCP

From PC can you PING your default gateway? Is it the PIX? Can you PING your DNS server? Can you resolve a name?

Can you post your PIX config and the output of "ipconfig /all" command?

This is my dhcp config:

dhcpd address 192.168.1.1-192.168.1.100 inside

dhcpd dns 212.216.112.112 212.216.172.62

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd enable inside

P.S.  The PIX 501 can be use in a network up to 50 users without problems.

Best regards.

Re: PIX 501 Moving off server DHCP onto PIX DHCP

router is at

192.168.5.1

DNS, Gateway, WINS, and DHCP all come up with this address as well.

I won't be able to test any suggestions until later.  The users in this office cannot go with any downtime so I can only do this stuff after hours.
