Take the tour ×  I'm having some trouble with forwarding DHCP
from a subnet behind an access list on a Cisco Catalyst 4500
switch. I'm hoping somebody can see the mistake I'm making.  The
subnet is defined like this: (first three octets of IP addresses
and vrf name anonymized)  interface Vlan40   ip vrf forwarding
vrf_name   ip address secondary   ip address   ip access-group
100 out   ip helper-address   no ip redirects  I tried turning
on a VMWare machine on this subnet that was configured to use
DHCP, but I never got a DHCP response and the DHCP server didn't
receive a request. I tried putting the following in the access-
list:  access-list 100 permit udp host host eq bootps access-
list 100 permit udp host host eq bootpc access-list 100 permit
udp host host eq bootps access-list 100 permit udp host host eq
bootpc  That didn't help. Can anybody see what the problem is?
• I know that the DHCP server works; our whole network is
running off of this DHCP server   • I also know that the subnet
works because we
