We have bunch of servers with two NICs, one is configured with internal IP and one with external IPs. Planning to use a single switch to connect them all together.
Here is the current setup:
--Router---Firewall--ExternalSwitch--NIC1
InternalSwitch--NIC2
Each of the server has dual NICs and we are connecting one NIC to 'external-switch' and one NIC to 'internal-switch'.
Also there is no internal-router we are using one of the internal IPs as default gateway, which i think can be left blank? The idea of using one switch came up since the external-switch was a 8-port one and was running out of ports. What is the best way to use the dual NICs in our scenario?
