RE: Access Internal and External Networks

My first inkling is that multi-homed systems cause more security issues and
more headaches than a properly configured NAT setup.  In addition, it can be
more easily made fault-tolerant now or in the future.

Just .02 anyway.

Subject: Access Internal and External Networks




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
