vLab for two subnets in one vLAN

Post by pprikrt@tsbohemia.cz »

I would like to ask if we managed to solve the problem with vLab for two subnets in one vLAN
When configuring vLab, I define a production PRIV network that uses AD (172.21.1.0/24) and SQL (172.21.5.0/24).

Subsequently, I try to define two interfaces in vLabAppliance to the same network PRIV but each time with a different "GW network" and masquerade:
vNIC1> GW: 172.21.1.254 masquerade 172.31.1.D for AD
vNIC2> GW: 172.21.5.254 masquerade 172.31.5.D for SQL

Unfortunately, the second interface still cannot be inserted

Hi Patrik,

I remember configured this multiple times.
Select Advanced Mode
Then configure 1 Isloated Network (both subnets are in there)
Then at network settings Add 2 vritual NICs and choose the same isolated network.

Hello,

You cannot assign multiple vNICs to a single isolated network, this limitation is described on this page of our help center.

But you may try to add the second vNIC with its own isolated network and to select the checkbox "Route network traffic between vNICs" in order to enable communication between isolated networks.

Thanks!

It is not possible.
Second vNIC cannot have the same Production Network. :(

I never heard of multiple gateways on a single system, even multihomed systems. It's easily possible to define multiple networks, even of different subnets on any single physical or virtual NIC, but generally only ever one gateway, at least default gateway. https://serverfault.com/questions/34703 ... e%20paths. Only thing I noticed that might be preventing you from completing what you want?
