VMware Fusion – Change IP Addresses

KB ID 0001147  Problem I use Fusion a lot, and it does what I want and never gives me any problems. I was working for a client this week and had to VPN onto their network (172.16.0.0/16 but all the servers were on 172.16.48.x). When connected I could not RDP to any of their servers? I asked a colleague to try on his laptop and it worked fine? I asked another colleague who also uses a mac, his worked as well. Solution I wondered if I...

Network Summarisation – Exam Technique and Examples

KB ID 0001138  Problem Note: Yes I’m spelling Summarisation with an ’S’ I’m English. Most examples I’ve seen on this give you a bunch of subnets then ask you to come up with a summary route for all of them, (that’s kind of the point of route summarisation, I’ll grant you). However in an exam with a laminated board and the dodgy permanent pen they give you to make notes with, are you seriously expected to...
