Comment 2 for bug 1639566

Compute node may use one external network IP (more simple case) or existing provider network IP but different routing rules will be required in both cases.

I propose that 'disable-snat' will be a limiting setting for 'Local SNAT' as well. If cloud admin set 'disable-snat' for some router - SNAT traffic should be disabled in all computer nodes for all relevant internal networks this router is connected to.

As a side note: 'Local SNAT' mode could use either manual setting for chosen compute node/s and have a client API for this. Or use automatic mode (detect external network) with configuration enabled option.
