When running on 8.4 i had a working config with the following scenario.
I have 2 interfaces configured as the outside interface.
One is connected to my internet connection
The other one is connected to a host that has a public ip.
The public host can access internet and also a PAT port on an internal host.
But after the upgrade the internal hosts can't access the external host but everything else on internet

Nat rules:

nat (inside,outside) source static IPv6_HOST interface service http http
nat (inside,outside) source static IPv6_HOST interface service ssh ssh
nat (inside,outside) source static INTERNAL interface destination static EXTERNAL EXTERNAL service apcupsd apcupsd
nat (inside,outside) source static IPv6_HOST interface destination static IPv6_POP IPv6_POP
nat (inside,outside) source dynamic any interface
The EXTERNAL is the host that is connected to an outside interface and that NAT rule works ok.
I can ping the EXTERNAL host from the ASA but not from the internal network.
Any ideas would be appreciated.
