Don´t you know any workaround? For instance in vCenter Appliance or VDR is the same case I cannot configure them in the normal way, but I can do it by CLI. ip: 5.39.20.126/255.255.255.255. And if I add this commands:
route add 5.39.73.254/32 dev eth0
route add default gw 5.39.73.254
it works perfect! But route add is not a command in vShield Edge.
I'm looking for something like that.
