Hi Seth,

It depends an awful lot on:
Size of area to be covered.
Number of guests who need concurrent access.
Regulatory/compliance/general security requirement applying to the
internal area you're trying to keep separate.

That said, my usual recommendation, for most customers' environments is
that unless the guest network needs to cover a huge area, it is usually
better to have a dedicated air-gapped network and internet connection
for guest wifi access. If it's only one area it needs to cover (EG a
lobby in one office), I have never seen an instance where it wasn't
cheaper to have a single dedicated internet connect and WAP set up for
this purpose.

I have seen customers' non-technical bean counters perceive a standalone
as, "spending more money on something we already have" when they hear
that routing it over the existing network is technically possible. It
needs *very* little work to be required, disruption to the internal
network internet access or even perceived risk to compliance/security of
the internal network before the cost of segmentation, testing/proving
segmentation and ongoing maintenance dwarves the $50 a month it would
cost to provide a standalone WAP.

Cheers,

Ceri

Subject: Wireless Infrastructure

I have a security related infrastructure question:

Proposal: Provide guest access to anyone at all remote sites.
Reasoning: Guests need to have a distraction for long wait times
(non-negotiable).

Solutions:
1. Create a Guest SSID and tag it with the external VLAN and then
tunnel the traffic back over the site-to-site VPN via the broadband
modem and route this traffic to an external connection over the same
link that provides internal VLAN traffic.
2. Build a separate infrastructure for wireless Guest traffic and
purchase a dedicated internet connection for all guest traffic per site.
3. ????

Help?
Thanks!!!
