It solved an IPSec issue we had with a customer. We have moved from Linux IPSec to Cisco.
I have used Cisco ASA products since 2010.
No, it's very easy to deploy.
With versions 8.4.4 and version 8.4.6, they had a lot of bugs. Also, after I moved to 8.4.5, route lookup changed to NAT divert and that kicked me.
No issues encountered.
No service.Technical Support:
Yes we previously used Linux and we moved because Cisco is great.
It was straightforward as Cisco Asia integrated it into OSPF, another router on the stack, and for NAT IPSec.
I implemented it by myself.
No other options were evaluated.
It's a great product.
