[rrevuru]

Hello

I have 2611XM has T-1 coming in to the WAN port.
I have the lan port connected to 3com access switch,which is connected to 48 clients.

I configured the DHCP server on the cisco 2611XM. For some reason. My clients are not able get an ip address from the dhcp server. Please let me know what am i doing wrong. I have the conf file below

The first question I have to ask is were are you inserting NAT? Your trying to setup a private ip behind your static internet ip. Is there a Firewall?


Here is the way I setup DHCP addresses


ip dhcp pool internal
ip dhcp excluded-address 10.x.1.1 10.x.1.10
network 10.x.1.0 255.255.255.0
default-router 10.x.1.1

Jeter:

Thanks for your suggestion:

Iam not using NAT, i did add

ip dhcp excluded-address 192.168.2.1 192.168.2.10
default-router 192.168.2.1

Here is what iam trying to do

I have a new T-1 comin into office and we have cisco 2611 and 3com acces switch,and i want to provide the itnernet access to 48 users connected to 3 com access switch

no offend rrevuru..but you're using NAT if you're using the 192.168.2.0 subnet.
Let me see if I understand is correctly.

I assume your T1 is coming into the serial 0/0, so you need to setup your fastethernet 0/0 as internal lan port, so this port connects to your switch.
Give the fa0/0 the default router ip address 192.168.2.1/24
Add the command ip nat inside to it.
At the serial interface, add command: ip nat outside

access-list 102 permit ip 192.168.2.0 0.0.0.255 any
ip nat inside source list 102 interface serial0/0 overload

"ip route 0.0.0.0 0.0.0.0 66.10.x.25" either change the .25 to .26 (which is your serial interface) or change the ip address to serial 0/0.
hope this helps.

Thanks mtelleka

It worked. But i have one more question,
how can i have 2 public IP address coming from Switch. Do you think creating sub interfaces ont the fastethernet 0/0 would give 2 public ip addresses from the switch.


Right now this the configuration for fast ethernet
**************************
interface FastEthernet0/0
ip address 192.168.2.1 255.255.255.0
ip nat inside
speed 100
half-duplex
****************


Let me summarise.. I have this fast ethernet going to 3com switch. I want to connect my file server and webserver to the switch.,and still would be able to get public IP address.

Thanks,
