As I understood U have smth like this :
Internet-----MyRouter----MySubNet
|----2ndRouter-----My2SubNet
Then U have to cut My2SubNet from ur MySubNet and configure
routes to appropriate subnets on appropriate hosts. As long as ur 2ndsubnet
is part of ur mainsubnet the hosts from 2ndsubnet will be seen from internet
& wise a versa. U may need to run DNS for reverse zone of ur My2SubNet

in fact this isnt big problem as soon as U have properly configured
subnets:) . Correct me if I wrong.
