Hi experts. I recently got a 5516-X as an upgrade over our existing ASA 5510. I have configured everything on the 5516-X as per the 5510 ie NATs, static routes, access list implemented on the outside interface for allowing access to servers on specific ports, andeverything else I can think of. The issue is that 5516-X still does not permit any inward access ie I cannot access our Exchange server from outside using browser. On the ASA 5510 it works perfectly with the same configuration. Is there any new hardened security on the 5516-X or do I need to add any additional configuration to make it work. Just banging my head really as I am out of ideas as to why it wont allow inward. Outwards access eg users browsing the Interent and all our VPN access both ways is working fine.
Many thanks for your input.
