Cisco network ASA 5520 & 877 VPN's dropping
Posted on 2011-03-11
I have a Cisco ASA 5020 in the head office (5mb leased line) with 7 branch offices using Cisco 877's + 8mb ADSL
Every site experiences several VPN drops throughout the day mostly only for a few seconds - is there any way to combat this.
Traffic is light - Email, web browsing (Through a proxy), RDP session.
Some sites are worse than others but overall none of them are reliable - We have one site using a 2mb fibre to the building leased line and drops occur maybe once every two days which is ok - Is it down to the ADSL quality in these sites or would ios / firmware upgrades help.
