Taking the second one first, that's just a matter of routing (ie do 
NOT configure Masq/NAT) between outside and inside interfaces.

The first one is trickier - you have the same subnet on internal and 
external interfaces which means you either have to bridge eth0 and 
eth1 or use proxy arp.

It might help if you tell us EXACTLY what information your ISP has 
given you about your IP allocations - the above looks rather unusual 
to me.
