Setup: 1605 running 12.0(5)T with IPFW w/ NAT(PAT) with one public on e0 and one private on e1.
I have turned off service dhcp and made sure no databases were define and no ip helper-address enabled, but everytime I scan the public side with nmap UPD it shows port 67,68,138 in the state open.
The results of show stack:
Minimum process stacks:
Free/Size Name
756/1000 c1000 LED
3692/4000 CDP Protocol
3716/4000 DHCPD Receive
2012/4000 Init
3452/4000 RADIUS INITCONFIG
3616/5000 DHCP Client
2012/4000 Virtual Exec
Interrupt level stacks:
Level Called Unused/Size Name
4 11548 1792/3000 CPIC interrupts
7 0 2976/3000 Programmable Interval Timer
Is the DHCPD and DHCP client have anything todo with the open ports 67 and 68?? If so, how do I close 67,68,and 138?
