DHCP request can't forward in Repeater mode... WHY?

Post by realtime »

DHCP request can't forward in Repeater mode... WHY?
This is my network topology
DHCP server <-ethernet-> AP(mikrotik) <-wifi-> Gargoyle AP(tl-wa701nd)[Client + Repeater] <-wifi-> WiFi client (like my netbook)

WiFi client can't take IP from my DHCP server.... WHY ?

Thanks!

Not sure, though I imagine it might have something to do with the fact that your Microtik AP is just that, an AP only, instead of a router with a dhcp server and wireless AP built into it. I doubt your Microtik ap is running Gargoyle since AP only mode isn't supported with Gargoyle. Is the Microtik at least running OpenWRT or dd-wrt? Can you confirm your network does indeed work if you assign your wireless client a static ip address?

With static IP address all work corectly.
In Mikrotik I can see DHCP request from client and answer to client, but client can't take this answer.
I think maybe UDP 67-68 port are ignored in firewall? or arpnat can't correctly do NAT for this request?
with tp-link factory firmware I can take dynamic IP by DHCP, but txpower is 14dBi and antenna settings are txantenna 1, rxantenna 3 ...
with Gargoyle I have txpower 17dBm and can set RX TX antenna to 1.
With OpenWrt firmware and installed relayd package I can recieve DHCP request too.

Gargolye is OpenWrt underneath the hood. Do what you did for OpenWRT.
