This sounds like there might be a firewall involved somewhere
between VPN server you connect to and your internal network? 
If that truly is the case, opening port on internal firewall
(between VPN server and internal network) for port 1521 ain't 
gonna cut it as only initial connection is established via this 
port and random dynamic port is used for each and every session 
(and opening firewall on port 1521 before VPN server would be 
inconsequential/wrong thing to do). 

Without firewall between VPN "edge-box" and your LAN, SQL*Plus 
should (must) "goe through" just fine... 

Lots of ifs so far, nevertheless I'll throw one more: 
if your Oracle server is Windows box, and if interfering 
firewall is not "SQLnet aware" (can not be configured to 
gracefully treat dynamic port feature of SQL net protocol), 
you might want to look for Metalink note 124140.1
