I'm having some difficulty in being able to access the internal network from a server in my dmz. From inside, I can ping and connect remotely to dmz server, but from dmz server, I cannot ping internally. I have tried opening icmp traffic, to no avail. I'm also looking to open a sqlnet port between the dmz server and an internal server. This is an ASA5505, Version 8.0(2), with a Security Plus license (20 VLANs, DMZ unrestricted, unlimited inside hosts). Also, when connecting via VPN, I can't ping or connect to anything internally or in the dmz. My configuration is attached.
