Hi Erik,

i would start with:

Checking the FW-Logs in -> System-Logs -> there should be an entry then,
which tells you also which rule blocks and what the incoming interface was.
checking the interface configuation -> Status Inferfaces in the WebUI
checking the routing of the pfsense -> netstat -nr - > either at the
console or at -> Diagnostics -> Command blah in the WebUI
Cchecking the NAT-Setup of the PfSense

if i remember correctly for checking the connectivity from the FW-Console,
one has to pass the source-address and/or the interface to the ping command.

this should bring you more insights and ideas on what is wrong.

if i remember correctly, parts of the interface assignment got changed
between 2.0.1 and 2.1 or so.
but i can be mistaken with this.
