Can someone enlighten me when to append no-proxy-arp route-lookup for the identity manual NAT/NAT Exempt for 9.9? Or is there a best practice for this?
Migrating from 8.2 to 9.9 is not an straight forward, you need to look upgrade path. ( i suggest to stick your latest OS with 5 Start rating, until you have rason to go 9.9)
there is lot of changes from 8.2 to 8.4, so i suggest to understand the chages and make the upgrade plan accordingly.
Yes, actually i'm converting the pre8.3 to post8.4 nat configs line by line manually. I'm just confuse when to append the no-proxy-arp route-lookup for the post8.4 nat exempt
Actually i will not do an upgrade, i will replace the 8.2 firewall with a 9.9 firewall that is why i am migrating the configuration manually. So for 9.9 NAT Exempt configuration, i need to append no-proxy-arp route-lookup?
Below doc can help you to understand more about proxy-arp, route-lookup are where to be used.
might this link could help/make your life bit easier to you convert the pre 8.3 to post 8.4 nat
