Office 365: Migrating To Exchange Online

KB ID 0001418 Problem This is Part-One of a migration from ‘on-premise’ Microsoft Exchange, to Office 365 (Exchange Online). I’m using my spare ‘test domain’ (.co.uk). And I’m using the 5 user E3 Office 365 subscription that the good folk at Microsoft let me have, as part of my MVP benefits. Note: I’m using Exchange 2016, with a ‘full-hybrid’ migration into Office 365. Step 1:...

Microsoft Azure To Cisco ISR Router Site to Site VPN

KB ID 0001220 Dtd 19/07/16 Problem Last week I was having problems getting a VPN up from a client’s Cisco ASA into Azure. This was because the Azure estate was using ‘route-based‘ or a ‘dynamic routing VPN‘. See the following article; Azure to Cisco VPN – ‘Failed to allocate PSH from platform’ So the firewall was a non-starter, but Cisco ISR routers are supported, and they can handle virtual tunnel...

KB ID 0001219 Dtd 12/07/16 Problem It’s been a week for strange VPN shenanigans with Cisco and Azure. I was liaising with an Azure service provider for a customer this week, and trying to get a VPN up from a Cisco ASA in one of our data centres in the UK.

Cisco ASA IVEv2 – ‘Failed To Allocate Memory’

KB ID 0001218 Dtd 07/07/16 Problem This week I was trying to get a VPN tunnel up for a client. They wanted a tunnel from their Cisco ASA into Microsoft Azure. Normally I’d use IKEv1 (because I know how to troubleshoot it!) But the guys running the site in Azure were using policy routing, which needs IKEv2. So I converted from IKEv2 to IKEv2. As I said I’m used to debugging IKEv1, but not IKEv2, so I was struggling to make...

Microsoft Azure To Cisco ASA Site to Site VPN

KB ID 0001166 Dtd 12/03/16ProblemGiven the amount of Cisco work, and the amount of Microsoft work I do I’m surprised I’ve never had to do this before. The call came in this week for a client who had a Cisco 5512-X firewall and wanted to get a site to site VPN into Microsoft Azure. Some efforts had been made, but the tunnel had refused to come up.Well I’ve never even logged into Azure,  (why would I ?) I work for a...
