OD going through four firewalls - anyone else encountered issues?

To answer the big question right away: no, we can't remove the firewalls.

Just as an offhand question, I wanted to see if anyone else had any experience with OD deploying through this many firewalls. We're having some problems, but can't figure out why, and we're in the classic "Firewall guys think it's the app, app guys think it's the firewall" situation.

Basically the connection is being made, OD is seeing it on the receiving end, but no data is going through. The users just see their deployments disappearing into a black hole and are not happy about it. To add to the fun, the issue is intermittent - there's no rhyme or reason as to why it's happening. There's no consistency on time of day, number of users, network issues, etc.

We've talked them down to two firewalls for some testing, but experienced the same problem. When deploying internally, with no firewalls, the issue does not occur. Obviously (to us, anyway) the multiple firewalls are the issue.

If anyone's had any experience with OD passing through multiple firewalls, I'd love to hear it, positive or negative. Any data would help at this point.

Release: TS & OD 7.2.0 (yep, 0)
Environment: Windows

I have done it successfully before. An old client has internal firewalls so you had to have requests to open ports between servers. Once it was running I never had an issue.

Since it often works and sometimes doesn't, you are going to have trouble. An all or nothing would be easy to check with telnet. You may need to set up a script (that you can write) to see if you can connect to the receiver and run it once every couple seconds. May have to do that on the receiver to connect to the sender as well, I have seen cases where traffic was configured to go one way through a firewall but the return ACK was dropped.

What OS ? Just use PERL LWP to open port 20014 on the opposite server.
