I have a company that has Fibre for their network connection as well as a DSL connection for providing basic Radio ISP to some users. They are now asking what it would take to utilize their Fibre connection for the customer side as well so as to expand the level of service they can provide on their Radio ISP service.
I feel there are some security risks in trying to do this. However, I know it can be done. the company does already have the necessary security appliances in place (firewalls, DHCP servers, etc)on their own internal network. I need to know if anyone else has ever done this and what issues they may have seen arise from this themselves. I.E. high impacts on companies own bandwidth (slower internet on their own internal network), hacking, etc.

Taking a different approach here:

I would suggest some sort of quantitative look at the traffic and current bandwidth use.

As I understand your post the "slower" DSL will be dropped in lieu of sharing the company's "faster" fibre connection with Radio ISP customers.

And that would drop the expense of the DSL connection - correct? However, what other equipment, if any, is needed? What about the associated support for that equipment?

What are the terms and costs of the fibre connection? Would the Radio ISP customers exceed any thresholds and add expense? Would the bandwidth consumed by the Radio ISP customers be at the expense of the company's bandwidth requirements?

Not questioning the concept per se and cannot really do as I...

All of your concerns are valid.

My concern is that the "devil is in the details" and that without a deeper look, including beyond just IT, things could go astray.

Even if any "issues" are not truly IT, IT will still take the hit. Get ahead of that possibility with some solid analysis and planning. Management may not listen or even want to listen. But then you will know where things really stand.
