I may have posted "newbie-firewall-on-RT-N16.69035" on the networking forum "by mistake" as it's more specific to setting up a firewall via tomato (well shibby tomato-K26USB-1.28.RT-MIPSR2-112-AIO.trx to be more precise). I'm a bit in the deep end as my linux knowledge is non existant and my networking knowledge is minimal. I've got the RT-N16 with shibby firmware behind a modem/router(as modem) and am not sure if I need to add any basic firewall rules etc. to have minimal level of security. The problem is I don't know exactly how to proceed - any pointers at all would be appreciated.
