AnyConnect: ‘Quick and Dirty’ Duo 2FA
KB ID 0001701 Problem Normally if I were deploying Duo 2FA with AnyConnect I’d deploy a Cisco RADIUS VPN on my LAN, (usually on my Duo Authentication Proxy). See the following article; AnyConnect: Enable Duo 2Factor Authentication However, last time I set this up, a colleague said ‘Oh by the way, you don’t need to do that, you can just point the firewall directly at Duo’. I was initially skeptical but I tried...
Cisco ASA VPN Static to Dynamic IP (DHCP)
KB ID 0001683 Problem I had a call with a client last week, they are in one of my employer’s DCs, and their servers are behind a vASA. They had purchased some Meraki MX devices for their IT team who were working remotely (during the Covid-19 lockdown), and were struggling. Normally we would just suggest AnyConnect, but these guys were building new machines for their clients, and needed access directly to the domain from their...
Cisco ASA: Mixing TCP and UDP in Object-Groups
KB ID 0001668 Problem I like object-groups, they can make your firewall configs a lot smaller/neater and if you need to add a host, network, range, or port, then you can simply add the new requirement to an existing group. But what if you want to allow both UDP and TCP ports, you can create a service group for TCP and add the ports and a service group for UDP and add the ports, and add them into your ACL where you would expect ports...
Cisco ASA – Update Activation Key (From ASDM)
KB ID 0001662 Problem I recently did a post on adding extra licences to AnyConnect, (with the current surge of people working from home). I exclusively work at command line, so when I was asked how to do the same in the ASDM I had to go and check 🙂 Solution Connect to your firewalls ASDM console, then navigate to > Configuration > Device Management > Licensing > Activation Key > Enter you new Activation Key > Update...
VMware Edge Gateway VPN to Cisco ASA
KB ID 0001658 Problem I was asked to setup a VPN to help out a colleague this week. When I had a look, one end turned out to be an Edge Gateway, I wasn’t that concerned, I’d done similar things in my prior role, I just didn’t have access to the vCloud or VMware at this datacenter. Depite my best efforts on the ASA, the tunnel refused to come up, it took a little looking ‘under the covers’ to accurately...
