[HECnet] netowrk flapping....

I guess that's the issue - you (or your router) really needs a way to statically define these associations (at least in some specific cases). I sort of assumed all routers could do that, but maybe I expect too much. Yup, that's basically a deficiency I've got... well, that and the fact that I can't stop it from changing my source port numbers. I needed this kind of router for VLAN support, so I'm missing a few features that lower-end models would offer like UPnP. --Marc
