I have an app that runs in JBoss on my laptop and a client connecting via an RMIAdaptor remotely. On my home lan this all works fine (all sits on 192.168.x.x). But when I bring it to a big corporate network where I plug my laptop (running jboss w/ my webapp) and it gets a dynamic ip and sits on 172.19.x.x, and then I try to connect remotely w/ my client on 172.17.x.x ... (via the RMIAdaptor) ... I always get the following.

How would I check to make sure that the path is clear (for 1099 I think) or whatever else is needed to make this work.
