Outgoing requests to match a specific IP
Hello, we have a computer that is registered to two IP addresses. I have
installed Tomcat on this computer and I have deployed a web application. This
web application does some XML processing and then sends a request to another
server. This other server is configured to only accept requests from a specific
IP address. Unfortunatelly this IP address is not the one Tocmat is bind to
when an outgoing request leaves. My question is how I can make Tomcat to tie a
specific request to otehr IP address, the one that is allowed to connect to the
second server. All information I have found so far is only for incoming
requests (listening) not for outgoing.
Any help is appreciated
Regards
Panos

Hi,
the outbound address is determined from the routing on OS level.
Fix your routes and the outgoing address is ok also.
If this is not possible, you can resort to NAT (network address translation).
This solution is used very widely.
regards,
R.

Hello Tim, thank you for your prompt reply.
Your solution would work, however we are using a third party API that does this
call to the specific server (actually what it is doing is to issue an HTTP
request to another Servlet), and I do not have access to the source code, nor I
would like to decompile the API and modify the source code.
Any other alternatives?

Its not a tomcat setting, it java socket programming.
http://java.sun.com/j2se/1.4.2/docs/api/java/net/Socket.html#Socket(java.net.InetAddress,%20int,%20java.net.InetAddress,%20int)
Whatever library is making the outbound call should have an option to choose
the local ip address the connection is bound to. If it doesn't, then you are SOL.
