benefits of centralising internet connection

Hi all

We have a central HQ with multiple worldwide sites

We are thinking of having all the internet traffic come back through the WAN and out of the HQ internet rather than each site have its own internet pipe.

what are peoples general thoughts on this design, good or bad ?

cheers

Carl,

Pros

- Centralised point of control and administration (firewall rules, IDS etc.)

- Possible lower cost (1 x 100mb internet connection is probably cheaper than 10 x 10mb internet connections)

- Possible lower hardware costs (1 x chunky firewall versus 10 x smaller firewalls)

Cons

- Latency - site internet traffic would have to traverse your WAN and then out of the central site adding latency

- Single point of failure - if your main site internet link goes, everyone loses internet access

- Rule complexity - your central site firewall will need to be configured for rules affecting all of your sites.

Personally I like this design model as it gives you a greater degree of control over your network.
