[Ninux-Wireless] batman-adv e vlan su tplink

Mer 16 Gen 2013 11:46:47 CET

In questi giorni sto sbattendo la testa per la configurazione del mio
router domestico tplink wr1043nd.
Questo router deve gestire la mia connessione verso internet (pppoe), oltre
che fare da gw_server nella mesh, collegato a sua volta ad una nanostation.

Sto avendo seri problemi nella configurazione dello switch integrato, unico
lato wan e lan/mesh.

La configurazione che desidero raggiungere prevede eth0.1 (porte 123) lato
lan, eth0.2 (wan/pppoe) ed eth0.3 (porta 4) per la mesh.

L'unica configurazione che attualmente mi permette di configurare la pppoe,
e mettere il tplink nella mesh è quella di buttare tutta la eth0 nella bat0
e disabilitare l'opzione enable_vlan nello switch.

Ho provato svariate configurazioni, come mettere tutto il bridge br-lan
(con dentro bat0 e eth0.1) dentro la bat0, anche allo stesso modo sulla
nanostation, ma l'unico risultato che ottenevo è quello di rendere i device
irraggiungibili su qualsiasi interfaccia, se a loro volta erano connessi in
ethernet.

La stessa configurazione però non mi permette più di accedere via ethernet
al tplink con i normali client della lan sulle porte della eth0.1.

Qualcuno mi da una mano?

Di seguito qualche informazione sulle configurazioni direttamente dal
tplink:
