static route on a o2 wireless II box?

Hi I wondered if anyone knows if I can set up a static route on my O2 wireless II box. I tried logging in as superuser but I couldnt see any useful options there either.

I have laptops connected wirelessly to the o2 box. I then have a netgear firewall connected to the o2 box and the netgear has various PCs behind it.
I want to set up a static route on the o2 box so the laptops can see that wired PCs behind the netgear.

thanks for any help/advice!

the o2 box firewall does a good job so remove the extra firewall and set up a home group on the machines which will also use windows firewall

unfortunately removing the netgear isn't an option.

I dunno if the command is removed on the o2 box but on the speedtouch 585 v6, the command is "ip rtadd" then it's got a little wizard to go through, if that command is there then its also worth checking what routes it has with "ip rtlist"
