I have a Linksys wireless router model BEFW11S4 and I
want to check whether someone is accessing the internet
through it by setting up a static route. Could someone tell
me please what should be in the static routing table if it is
left untouched? At the moment, I have the following
showing:

Destination LAN IP 0.0.0.0 Subnet Mask 0.0.0.0
Default Gateway 192.168.0.1 Interface WAN

Destination LAN IP 192.168.0.0 Subnet Mask
255.255.255.0 Default Gateway 0.0.0.0 Interface WAN

Destination LAN IP 192.168.1.0 Subnet Mask
255.255.255.0 Default Gateway 0.0.0.0 Interface LAN

Are these entries made automatically by the router? Or
must someone have put them in there? What do they
mean?

Could someone also explain to me why my incoming log
sometimes consists of a whole load of 0 entries, with
source IP listed as 0.0.0.0?

Cheers, Aylla

Do you have the security features turned on in wireless? Disable SSID broadcast. Set WEP. Enable MAC filter. Change you user password.

Yes I have WPA set and regularly change user password, SSID
disabled with regularly changed name, MAC filter on and IP
addresses limited to number we use. Someone thought we
maybe being hacked into through a trojan worm on one of
the PCs - they've both had Windows reinstalled and been
scanned with Norton, but if something is still there, we're
going to have to completely scrub the hard drives. I'm not
sure anyone is still getting through - but I wanted to check
that the static routing entries are normal. If they have to have
been input by someone, then that someone is not me!
