ACL dont allow dhcp

[lima.pedro]

Hello sir, how are you?

I have 2 vlans over one port mode access, follow example of acl:

permit ip 10.1.1.0 0.0.0.255 10.1.1.1 0.0.0.0

permit ip 192.168.7.0 0.0.0.255 192.168.7.0 0.0.0.255

I wish to get dhcp but I dont receive request.

Every time i get APIPA address of windows.

How can I able dhcp request and server talk over this acl ?

The ip of dhcp sv is 192.168.7.1

Thanks so much!

1) you need to allow the dhcp-traffic in the ACL. Most easy is to restrict only on the ports, but it could be defined more granular:

permit udp any eq bootpc any eq bootps

And you need to send the DHCP-packets to the server:

interface vlan X

  ip helper-address 192.168.7.1

Hi,

If you're getting an APIPA address that would mean your PC has limited or no network connectivity.

Check Layer 1 and try to ping 192.168.7.1.
