Vcloud SNAT RULES

Hi to everyone,

I have built a Vcloud Director 5.1 lab with Vshield 5.1.2 with following spec:

one External network pointing to internet with network 192.168.0.0/24 and a VCD network with 172.16.1.0/24 connected to VSHIELDEDGE.

If i connect the VCD network to VAPP my ping to EXTERNAL NETWORK not working.

I also create a SNAT rule from the address of VAPP (172.16.1.100) to SUBIP allocated (192.168.0.60) in the VEDGE in fact when i try to ping my external gateway (192.168.0.5) the

translated IP (192.168.0.60) say destination unreachable..

I want to know what is the exactly configuration of the VCD network to ping my external network gateway and if Vshield need two interfaces rahter than one by default.

Any advice is appreciated and some considerations about this issue.

Thanks

Giovanni
