If packets are dropped, increasing timeout will not help. There are things in this world which cannot be done by modifying oracle parameter values.

Oh boy! You need to fix that firewall. You should a) allow your local nodes to go out on Oracle*Net port (and I advise against 1521, 1526 and 1527). b) allow certain IP addresses to go in your LAN by using Oracle*Net port.
Second thing to do would be to have a SSL firewall and use Advanced Networking or, alternatively, configure Oracle*Net to tunnel through firewalls by using ssh. The latter is described on in the following article by R. Schrag: http://www.dbspecialists.com/presentations/net8_security.html
There are tons of options for you and I could easily write an article about Oracle*Net and firewalls (Thermopilae in Greek). The best thing to do is to read a few articles about firewalls and Oracle*Net until you find something that fits your needs. It's half past midnight and I'm tired. May gods be with you. There was a guy named Leonidas who was the original security administrator at the original firewall. Be brave, your work is much easier then his was.
