Hi

I´m testing the Gateway roaming capabilities of Batman-adv (using 2011.1.0 version). I setted two computers as Gateway servers with DHCP servers running on them and other as Gateway client, configured as class 3. Then i stressed individually the Gateway server´s links to make the client choose the not stressed one. I confirmed that when te client sends a layer 3 broadcast DHCP request, Batman redirects that request only to the best gateway. However, when the original gateway becomes worse than the alternative, and the client chooses the new one as preferred (observed with batctl gwl) i noticed that the subsequent request DHCP messages are sent to the original server, even if it doesn´t have the best link.

I guess that´s because these subsequent DHCP requests are made as Unicast to the original server and so Batman doesn´t redirect them, but i wonder how this behavior affects the network balance, because the computers would get tied always to the original DHCP and IP default gateway even if they moved, right?

Thank you very much
