Brocade ADX – NAT

Within this article we will look at the two ways in which to NAT traffic.

Source NAT Pool

This examples provides the commands required to configure source NAT via the use of a pool and ACL. This allows you to source NAT a number of internal hosts behind the ADX to a single IP address.

Here we will NAT the servers and to the source IP address (when traffic from these servers is sent out through the load-balancer on port tcp/80).

ip nat inside source list 150 pool SNAT overload

  ip nat outside

int ve20
  ip nat inside

Server NAT

Another common scenario that is required (to ensure that traffic is routed back through the ADX) when either configuring remote servers or internal load-balancing is to configure server source NAT.

This ensures that any traffic from the ADX to the real server is source NAT`d behind the egress interface of the ADX.
