I see this behavior both in 2.0 and 2.1rc2
 
When I connect Squirrel via VPN, I can connect to the databases just fine and even open the list of tables. But when I click on columns or contents tabs etc, I get the error:
 
java.sql.SQLException: Io exception: invalid arguments in call
 
But the same client works fine from work!
 
I'd appreciate any help.
 
Thanks
