Hello everyone, I receive an internet link, the delivery mode is via DHCP, I receive it on router 1, from router 1 it is connected to a switch, from the switch it goes to router 2 and from router 2 it is connected to router 3.
I need to pass this DHCP Client to Router 3, so I created a bridge on Router1, I put the traffic that enters through this port where the DHCP server is, it is untagged and vlan ID 100, so I passed this vlan tagged to the switch, the switch passes this vlan to router 2. Router two, if I create a dhcp client on top of this vlan100, it receives the ip normal, everything working, but when I switch to router 3 it cannot receive, it seems that there is something in the router 2 that is blocking the packets, the DHCP request is sent but does not receive the response, as if router two were doing a drop dps DHCP packets, is there a way to solve this?
Remembering I switched vlan100 from router 2 to 3.
I did it in two ways, the first was to create a bridge, between the ports coming from the switch and going to the router3, in bridge>Vlan I put that the vlan100 is tagged on these two ports, it didn't work.
So I created two vlans in router two, placed the two vlans inside the bridge, placed the ports that come from the switch and goes to router 3 and in router 3 I created a vlan in the case of 101, it also didn't work.
