One of the challenges faced by some network administrators is how to manage an established Cisco vpn tunnel, given that most of the times, the vpn setups are not configured by these administrators. Administering an already installed vpn server will include adding new networks to the ipsec proposals. Unfortunately, this is where some network administrators find it difficult as a result of little or no knowledge of the workings of ipsec vpn. In this piece, I will share on how to add a new network to an established Cisco ipsec vpn tunnel.
To understand the need for this post and the configurations that will be entered, you are to read my previous post on how to successfully configure Cisco IPsec vpn in 5 minutes. Please, find here. This post was borne out of the questions I received from readers of that post.
