Access Internal and External Networks

[<william () orlitech com au>]

I have a need for some servers to access both the external network and the internal network and am wondering which 
approach would be best:

1. 2 NIC's in each server one connected to the external network and one connected to the internal network

2. 1 NIC in each server connected to the internal network and DNAT the required ports from the external address to the 
internal address

Thanks

William
