Hi,
I get 2 cisco 1601
T1 line connected Main office and remote office.
Main office: Windows 2000 server with DHCP, DNS and Win server.
Remote office: Win98, Win2000Pro and XPpro workstation.
I can ping IP address and Host name from my remote office workstations(use static IP address)to the DHCP Server.
But my workstations at remote location unable to get the IP address from the main office DHCP server. And Cannot go to the internet though Proxy Server port 8080.
How can I enable tcp port to allow the traffice between both office?
My router configuration as following:
version 12.1
hostname router
ip subnet-zero
no ip finger
interface ethernet0
ip address 192.168.26.1 255.255.255.0
Interface Serial0
no ip address
shut down
no fair-queue
interface Serial1
ip unnumbered ethernet0
ip helper-address 192.168.25.21
router IGRP1
redistribute Connected
network 192.168.26.0
ip classless
ip route 192.168.25.0 255.255.255.0
no ip http server
dailer-list 1 protocol ip permit
line con 0
Transport input none.
line vty 0 4
password
login
Any ideal I can fix the problems, Thanks.
Any other question, Did Cisco router default all tcp and udp port are open or closed.
Thanks,

try to add the command router(config)#ip dhcp-server address
where address is the ip address of the DHCP server

Dannie,
When i look in your config i see that you configured the helper-address on Ser 1.
The helper-address should be configured on the incoming interface.
In your case ethernet 0 on the remote router.

Hi.
As Mario wrote, you should configure "ip helper-address" on the ethernet interface and your static route should point to something like serial 1... "ip route 192.168.25.0 255.255.255.0 serial 1", if your router isn't learning that network via IGRP.
