Has anyone got Oracle running through a simple, internal ipchains firewall? I'm running RH6.0 patched using the current RH6.0 updates archive on a machine with two network cards. I've opened the Oracle TCP port (1521) through the firewall, but the NT Oracle 8.0 client can't "resolve" (an Oracle term, not a DNS thing) the server using that port alone. The server is a Solaris box. I tried enabling all TCP traffic but that didn't improve things. It did let me telnet to the Oracle server though. The NT client can successfully do the DNS resolution of the server from the firewall PC, and if I open all traffic between the server and client through the firewall the connection does work. Is there some port or protocol other than TCP 1521 that I need to allow through too? Vik :v) -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
