Should I expect Internet service providers to charge extra for any other IPv6 migration costs?

They employ 24 staff comprising of a CEO, 5 administrators, 2 business development managers and 16 specialist consultants. The administrators and business development managers use PCs but the CEO and consultants all use laptops. The company operates a database server for the storage of company and customer records, including an archive of all previous work and reports produced. In addition, they have chosen to maintain their own Web server on-site; the content of which is maintained by the business development managers. Access to the Internet is provided via a 2 Mbps Digital Private Circuit to an ISP who is also responsible for providing the company’s email service. A total of 16 public IP addresses have been made available by the ISP to our company. However, all staff needs access to the Internet whilst working from within the business unit.

The nature of the work carried out by this consultant agency is such that the consultants often spend several days away from the office but there are occasions when all staff are present in the business unit at the same time. Nevertheless, whether a consultant is in the office, at a customer’s premises or at home, they expect access to the Internet, email and the company’s main database server.

What would be the best infrastructure or design given this situation?

Currently, we are using one link. Another link is new. I want to do load sharing and redundancy between them. Right now I am not using BGP (routers are configured in simple manner). My client and I are concerned with cost.

My present network scenario looks like this:
Internet Ri (ISP 1) — Layer 3 switch (working here as a simple switch) — Firewall 1 (Cisco ASA5510) — Firewall 2 (Cisco ASA5510) — LAN.

On Firewall 1, remote and site-to-site VPN is configured — one DMZ. My LAN is in the 172.16.1.xx series; my DMZ is in 172.16.4.10, and after 172.16.1.30 is used for the desktop, 192.168.x.x is the management IP.

Right now I have one other Internet link (512kbps) from a different ISP. So please tell me how I can accomplish load balancing with redundancy.

I’ve tried OER but unsuccessfully, due to IOS image (c2800nm-ipbasek9-mz.124-11.T.bin) and ISP’s AS. Can it be possible through natting, and ACL? Please help me with the OER or anything I’ve mentioned. If possible, please show me a sample configuration.
