Have you verified that the box that's not receiving the connections has the appropriate host servers running? And if they are running are there any exit points to monitors that might be denying the connections based on user or source ip?

Subject: Re: JDBC requests (whether from Java or from RPB via JDBCR4): how does one set a specific "from" IP address when connecting?
Importance: Low

Yesterday, I wrote:
We're having an issue with communication between two midrange boxes on
opposite sides of a firewall, with the requests coming from a box that
has multiple IP addresses. We've got a proprietary protocol connecting
just fine, but JDBC isn't connecting at all, and we suspect it's
because the firewall is rejecting the "from" addresses.

Latest news is that they supposedly opened up (at least on a temporary
basis) ports 449, 8470, 8471, 8476 in the firewall to traffic from anywhere, to the point where (at least in theory) we could use SQuirreL to connect to it from here, but still nothing is getting through. (But at least that gives their firewall people a way to work the problem on their own.)

(Needless to say, that's one more reason why I can't specify who, what, or where, or what IP address!)

Anybody have any further insights? This is definitely weird.
