SA 520 Multiple subnets on one VLAN?

Answered Question
Nov 23rd, 2011

I'm posting just to make sure...

There seems to be NO WAY to put disjointed subnets on the same VLAN ID.  The web based config limits it to ONE subnet ber VLAN, and I know that the underlying OS can do more.

What I was trying to do is this:

VLAN 1 - Default  - subnet 192.68.75.x  (used as deadspace)

VLAN 20 - Data  - subnet 192.168.20.x   AND 10.0.20.x

VLAN 100 VoIP - subnet 10.10.20.x

There's no way that I can see to put both of those subnets on VLAN 20.  Yes, I can say that I'd like to create a fourth VLAN for the odd subnet, but some design issues are beyond my control.

I'd like to be using an ASA, but I wasn't involved in the original hardware purchase.

Has anyone found a workaroud for this type of config?

Any pointers would be appreciated.

Hi -

Unfortunately that is going to be a limitation of the SA series. You can only configure one subnet per VLAN.

Wish I had better news.

Thanks for the official 'Thumbs Down' on this issue.

I won't be recommending this unit to anyone else in the future, for sure!
