 ===== Portal access =====
-pinnacle-portal can't be forwarded the same way. We are working on getting the host certificates we need for a portal.
+===== Open Ondemand Portal Access =====
+The other popular method for accessing AHPCC resources is the Open Ondemand portal.
+**On-Campus**
+On-campus and UAF VPN users can access this service via the URL:
+  * **''https://pinnacle-portal.uark.edu''**
+**Off-Campus (Non-research/commodity network)**
+Others (off-campus) can access the Open Ondemand portal, by registering the client machine source IP, as described above.  Once registered, the URL below, forwards the connection to the Open Ondemand portal.
