Multiple DHCP servers, networks, Vlan Help one doesn't work!

RouterOS General

Hey chaps, I really hope someone can help as I’m baffled!

I have four networks each on its own VLAN with its own DHCP server and external IP address I have set them all up the same however one of them (Vlan 30) refuses to assign DHCP!

Can anyone help me? below is my complete configuration

Hello,
what devices are tagging into vlans your own network?

And can you ping gateways from router? :slight_smile:

3

For testing I have a machine setup on a cisco with a 802Q configured port when I tag this as Vlan29-30 I get the DHCP correctly and all is happy however when I choose VLAN31 I get nothing!

yes all gateways are responding (192.168.29.1, 192.168.30.1, 192.168.31.1 and 192.168.28.1)

4

bizarrely even when setup with static ip on vlan31 i can’t see anything

5

Config looks fine, chances are it’s the switch. Possibly not having having VLAN31 listed as a tag on the interface. When you run torch on your physical LAN interface, and select VLANs, do you see anything from VLAN31 coming in or going out of the router?

6

AH I hadn’t considered that as in the past its just worked but no nothing on Vlan31, I wonder if it just takes a while for the cisco to pick it up.

Will look into that now!

Thanks

You are absolutely right! Cisco problem!

Thank you
