[B.A.T.M.A.N.] non DHCP batman-adv gateway

[B.A.T.M.A.N.] non DHCP batman-adv gateway

[Gabriel Tolón]

Hi,

I'd like to use a configuration in a batman-adv openwrt mesh network in 
which the batman gateway relays the DHCP messages to and from a non 
batman-adv router. I think that's not a typical configuration right? 
Should it work? Do I need some additional packages? Thanks in advance!

Gabriel

Yes, it should work just fine, you should set gw_mode=master in the
correspondent batman-adv gateway, but turn its dhcp server off.

So, when dhcp packets get to that node, it will naturally relay them
over br-lan and they will reach the non-batman-adv router.

That setup is more typical than what you might think of :)

(we have used it this way in at least 4 or 5 different cases)

cheers!

you mean gw_mode=server? Or it's a new option?

That's good to know. Other option I had thought was to turn off gw_mode 
and use the mesh just as the L2 switch it is, but that way the 
possibility to choose the best batman-adv gateway would be lost i guess.

yes, definitely. my mistake. It's gw_mode=server.

cheers!
