I googled your question and found homework assignments. So I can't draw this for you.
What I can do is share how I draw such. I'll use a pencil and paper for the first rough draft. Then re-do until it's close enough. Then I'm off to a drawing program on my computer. There are now so many fine drawing programs that it's best you go with one you know.
Hi, can anyone help me draw a diagram for this question?
A company has an office based in London with a network that houses two web servers. One of these web servers is designed for external access, the other is an intranet web server designed only to be accessible to employees of the company. The company also has another office located in Paris, which is externally connected to the London office through a virtual private network routed over the public internet. This virtual private network must always be active, and not raised on demand by individual members of staff in the Paris office. Both offices continue to use IP version 4 addresses, but the company only has a single public IP address range of 126.96.36.199/26. They require more nodes than the 62 allowed by this range, and so all nodes in the networks are numbered with private addresses from the 10.0.0.0/8 range.Describe, with the aid of a diagram, a network topology that will interconnect the two offices and that will also allow public access to the external facing web server. You must clearly identify all routing or switching components required, and label IP addresses and subnets for at least one node in Paris, one node in London and all other identified components. Use Classless Internet Domain Routing (CIDR) notation to label the subnets. The diagram should also indicate how the routing of private addresses to the Internet is achieved, and the function of the relevant components should be described. (25 marks)
Answer Pointers The private address range must be split into at least 2 parts. For instance, the London network could be 10.1.0.0/16 and Paris could use 10.2.0.0/16. These networks are then routed over a VPN that should be achieved in a router, e.g. an IPSec router. The answer does not require any specific VPN, but the candidate must recognise that there needs to be a point to point VPN over the routers through the public Internet. Both offices need a VPN end point that acts as a router, tunnelling encrypted data over the public internet. This VPN connection then handles the internal routing between subnets and there does not need to be any network address translation (NAT) at that point. (10 marks) Outward connections from London do require NAT, and the Network Address Translator should be clearly described showing how one or more public IP addresses may be shared through the NAT, substituting the public addresses for the non externally routable private addresses. This is most concisely describe by drawing up the NAT translation table showing the mappings of public IP addresses to private addresses and how the router rewrites the IP header with these addresses. Candidates will usually be more familiar with NPAT, sharing a single IP address. NPAT answers will be awarded most of the marks but an extra 2 marks are given to answers that recognise that the pool of 62 addresses allows a NAT solution without recourse to Port Address Translation. (8 marks) The Web server must have a public address, and may be located either on the external side of the NAT, or else within the NAT with a private address and a static mapping for one of the IP addresses. Both answers, if correctly described, carry full marks. (4 marks) The intranet server should not have a public address, and must be placed inside the privately addressed network with suitable IP address and subnet (e.g. 10.1.0.1/16). (3 marks)
