Just a little question, how do I turn on the firewall in Huawei Quidway WA1003a modem router (it has one LAN port and integrated Wireless LAN)? It is working in bridge mode.I tried to turn on NAT firewal from the web interface, but it asked me to choose a LAN client before doing that.If someone could give me the steps to do this, it would be great. The documents available online (its userguide and the Calcutta Telephones webpage (based on flash) ) do not really explain this particular thing.thanks.
