I'm in a hotel which doesn't allow vpn out, so I don't have the config to post right now. Hopefully my explanation will give enough information to get some good feedback.
4 VLANS on Cisco 3560 switch.
VLAN 100, 111, 112, 113
DHCP Server is 192.168.100.3
I configured each VLAN with the ip helper to 192.168.100.3. inter-VLAN routing is working fine.
Hosts on VLAN 111 can not get an IP address from the DHCP server.
If I remove the access-lists from both VLANs then everything works, so I'm thinking thre access-list is blocking some necessary port. We tried allowing the two dhcp related UDP ports through but it didn't work. Wondering what other ports to try.
For a variety of reasons I need to block access between the VLANs all but the absolutely necessary ports.
I do not know if the virtual intefaces are configured for ip directed broadcasts or not. I'll check that tomorrow.
Any suggestions on what else to look for?
