Hey networking folks, I have an interesting problem:
I transparently connected two home networks using a beam radio. I'd like to have more control over which side's DHCP server is used on the respective sides.
Is this possible?
Right now my local devices often end up using the DHCP and thus the internet gateway of the remote site, which has much slower internet uplink. Local DHCP server can be controlled well (router running LEDE), remote one not so much (a Fritz Box).
I haven't figured out why my local devices seem to prefer the remote device's IP address. I had assumed that due to the latency of the beam radio uplink, the DHCP answers of each respective local router would go through faster; but that just adds a negligible 2ms of latency (which is great! For most things...).
Or maybe you don't have an idea, but can tell me how to debug the DHCP communication between my devices (perhaps with Wireshark, can it do that before an IP address is even assigned?)?
@natanji
You could configure one DHCP server to only give devices with a specific MAC address an IP address, so the clients on the other side can't use it. But then guests can't either...
So I guess the networks have to be separated somehow.
Maybe have a separate SSID for guests?
