I have a old BSNL DNA-A211-i modem, which I would like to use to share the Lan of the reliance wimax . Is that possible? I created a IPoATM and put in the ip, gateway and dns of the reliance server, but the modem does not seem to connect.Can the 4 LAN ports be used as a shared LAN, with the internet on port 1, and the rest as normal outputs?
