I think I don't need to enable ip forwarding. My problem is when I try to,
for example, resolve some name address via eth2. My DNS server denies all
querys because these appears with 172.25.70.18 ip instead of 172.25.80.10
IP.

This is one problem. Another problem for example is when I try to
synchronize host time using ntp service via eth1. Doesn't works.

Thanks.
