OK, scratch that. Pretty much eliminates that theory, then. > Tracerte is not very helpful, either. It seems to confirm what the firewall guys said. Yup, although firewalls are usually a layer 2 device, so won't always show up in traceroute. I was looking for whether the traffic might have been going somewhere unexpected that did pass through a firewall. Looks like it's not. > What is the difference between the NJE keepalive and the RSCS keepaliv=yes? > We have tried both =yes and =no to no effect. Same thing. Since the RSCS keepalive essentially does a simple NJE transaction periodically, and it doesn't look like a normal TCP timemark. I'm almost tempted to ship you a copy of our NJE Bridge and see if it's an implementation-dependent thing. That would at least identify which implementation is doing something weird.
