This causes the NFS stores to go inaccessible for the ESXi servers whose first packet comes back the "long" way. However, the Ubuntu and sometimes Mac clients on the 12.x network ask the 10.0.12.1 firewall and it sends the first packet goes through the gateway, and then gives the hint on the second packet to go through the "direct" 10.0.12.3 connection. The ESXi hosts a static route, which they honor on the first packet. The routing technically works, but NFS targets are failing between the Ubuntu NFS servers on the 10.0.12.x and the ESXi servers on the 10.0.2.x networks. Yes, it would be nice is the first packet goes through the "direct" way, but Ubuntu and the Cisco gateway we use don't seem to do static routes the same as our older slower one. The default connection goes through firewall/gateway and through the VPN tunnel, and the firewall redirects on the second ping to go through the faster "pipe" that is direct. Have two connections to another network in separate buildings on same campus.
