Hello Experts,
I'm setting up an ASA 5520 with a basic config and am having connectivity problems on the inside interface. I can ping across the ASA but can't connect to network shares, RDC, etc etc.
Can some see what is going wrong? I've attached the config below,
Traffic to the internet and inbound traffic on the outside interface is fine.
For example if I try to remote desktop connect to 172.16.7.1 I get a teardown with reason TCP Reset-O and that just doesn't make any sense as I can ping 172.16.7.1!!
