static translations via OSPF 7.0(4) to 8.0(2) upgrade
We have an ASA5520 running 7.0(4). This firewall has several static translations and it is announcing these out the outside interface via OSPF. I recently tried to upgrade to 8.0(2) and the firewall stopped announcing these translations. Why did this change?

Matthew, refer to this thread as it seems you may have had the same issue with"sysopt noproxyarp outside" during upgrade process, if this is the case it is good for cisco to collect this info to try figuring out why this command is placed in fw when upgrading to 8.0 , this disables proxy arp , issue " show running-config sysopt" if seen as "sysopt noproxyarp outside" you must enable it by "no sysopt noproxyarp outside" in order for fw outside responds to arp request for your static translations to inside.
