Re: ASA Static translation - will this be a problem?
Both of your methods will work (I've used both before).
However using a 10/8 static will use identity NAT whereas nat 0 ACL will do NAT exemption. I prefer to use NAT exemption because it's a bit neater and it won't show up in "sh xlate". If you're using identity NAT you can't see the wood for the trees when trying to get a quick view of all your current NATs.
Seeing as NAT exemption bypasses NAT all together perhaps it saves on system resources too???
