Re: Blocking specific IP's
which TCPIP stack are you using ?
For HP TCP/IP, you can reject connections from specific host at the TCPIP service level, e.g.
TCPIP> set service ftp/reject=(specific-host-ip)

Re: Blocking specific IP's
sorry, Mark's example is correct, mine isn't. You need to specify /REJECT=HOST=xxx

Re: Blocking specific IP's
Then use set [conf] comm/reject=host=
(with conf after set when perm db must be modified).

Re: Blocking specific IP's
You can hack around that with various commands and such (and for specific IP hosts), but for lower-level IP traffic a decent consumer or "pro-sumer" grade firewall (or M0n0wall or Smoothwall) will likely work just fine for this task.
As for what ports Oracle uses, check the Oracle documentation. That stuff can vary, though most any vendor that needs IP ports will document that. (Google with the site keyword (eg: site:oracle.com) can be very handy for finding this detail.)
The other approach here is to use a VLAN construct. Most mid-grade managed network switches can provide this capability, and this is ideal for isolating network traffic. (Which reminds me: various managed network switches can also provide firewall capabilities.)
Here's a more general write-up on using a firewall with OpenVMS, and why I recommend it to my customers:
