A hub with a web based configuration app? Mine is also from corega but it's
dead simple.
I couldn't find one on the corega website that can do this.  Isn't that web
based configurator for the adsl router??

Anyway, you didn't give enough info on what subnet is masqueraded on the ADSL
 router.
My simple guess is that 192.168.1.* is not, so when the packets get back to
the router originating from 192.168.1.11 they are not NAT-ed.
Did you try turning on masq on the hub ?

BTW, why do you need that port forwaring/masq feature in the hub (if it's
real)?  Seems like an overkill to me.
