Description:
On-campus staff cannot connect to /V however they can connect to /M.
Staff can connect to both URLs (/M and /V) remotely.
All ports are open except port 25.
Our library's IP range is: 123.123.123.000 to 123.123.123.255
This doesn't appear to be a firewall problem if you do the request manually using telnet:
telnet <IP address> <port number>
Then type either "GET /M" or "GET /V" followed by the enter key; the /V returns a blank page.
Here is the output from when our systems person did the telnet test:
48-186:~ mrmorlino$ telnet www.library.com 8331 Trying 123.123.123.123...
Connected to www.library.com.
Escape character is '^]'.
GET /M
HTTP/1.1 200 OK

Our firewall admin enabled firewall based IP debugging on the server and confirmed that we are accepting connections from this IP; the last connection was Today
This would rule out any firewall issue
We tested both interfaces from multiple sources (internal/external) and verified successful connectivity using both IE and Firefox.

Resolution:
The cause of this behavior was due to missing information in column 4 (institution code) of the ./vir00/tab/default_z312 table.
The only IP line containing an institution code is the 'catch all' IP; this explains why everyone in the world can see the /V except the people on campus.

WRONG:
>> cat default_z312
!ip-from ip-to default user id default us
!!!!!!!!!!!! !!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
111222333002 111222333003 LIBRARY-ENG-IN
111222333000 111222333255 LIBRARY-ENG-IN
000000000000 999999999999 LIBRARY-ENG-GUEST
LIBRARY LIBRARY-ENG-GUEST LIBRARY
METALIB METALIB-ENG-GUEST METALIB

CORRECT:
>> cat default_z312
!ip-from ip-to default user id default us
!!!!!!!!!!!! !!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
111222333002 111222333003 LIBRARY-ENG-IN LIBRARY
111222333000 111222333255 LIBRARY-ENG-IN LIBRARY
000000000000 999999999999 LIBRARY-ENG-GUEST LIBRARY
LIBRARY LIBRARY-ENG-GUEST LIBRARY
METALIB METALIB-ENG-GUEST METALIB

Please note: There can be only 1 "catch-all" line in this file, that is:
000000000000 999999999999 LIBRARY-ENG-GUEST LIBRARY
