hi paul I am new building images for devices but am learning to use that and i like to know whether you have implemented PPP and were successfull in filtering the traffic which is not useful and always resets idle timer in demand dial mode . did you use active filters or the precompiled filter ? if so can you please share your knowledge. problem description: the bellow expression doesn't filter any traffic and keeps the link up active-filter 'outbound and not (icmp[0] = 0)' and where as active-filter 'outbound and (icmp[0] != 0)' doesn't allow any traffic to make the link up.... thanks in advance for much needed help. regards, rajendra -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
