Printer + PIX DHCPD

After recently dropping a PIX in place of an old linksys router the
laster printer on the network can no longer get an IP address however
every other PC on the network can. Any ideas?

Also, the PCs have lease times MUCH longer than the printers NIC ...

192.168.1.109 0100.0ea6.ae5f.3f 74455 seconds

192.168.1.110 0100.0c6e.1f7d.cc 54254 seconds

Q1 What version of PIX software ?

Q2. The default lease time should be 3600 seconds. Try configuring the
lease time "dhcpd lease 3601"

Q3. Capture the DHCP packet exchange between printer and PIX using
Ethereal or equivalent to see if pIX is respond to DHCP request from
printer

A1. PIX Version 6.3(4)

A2. It's currently set to 86400 - I will try 3601

A3. Can I do that right from the PIX somehow?

try capturing and posting:

debug dhcpd packet

debug dhcpd event

Where is the debug text sent?

depends on how you configure logging

to see output on telnet session, configure:
logging monitor debugging

to save debug messages in internal logging buffer, configure:
logging buffered debugging

then show logging buffer
