Home -> Community -> Mailing Lists -> Oracle-L -> RE: [Q] sqlplus through VPN not work, but tnsping work
Well, someone finally hit the nail on the head. Sorry, but I've been
too busy to read & reply. VPN software makers normally block telnet
traffic and Sql*Net is something like Telnet traffic as I understand
from my network engineer. But they also each have a way to recognize &
permit Sql*Net traffic as a subset of telnet, without opening up telnet.
Have your network guru look at the software & set it up accordingly.
It's what we had to do with Neoteris.=20

most firewalls have modules that will direct SQL*Net traffic through one port. you need to get the firewll admin to look into getting and configuring the SQL*Net proxy for whatever firewall you have. that way they only have to open one port for all the traffic.
