btw--I set up the G4 with LW to share only the test magnet, and a request there also triggered the NPE (the magnet was received correctly--thanks guys).

This revealed quite a few other issues. Comment, suggestions and info would be appreciated. I'm probably misunderstanding something here.

--should I send in every automatic bug report of the same error? (I only send in one per session and discard the others)

--Which help the gnet more--sharing or running as an UP? Both LW's do run as UltraPeers simultaneously. The G4 only shares 1 file, but running by itself 24/7 will use up almost all of my "ISP-below-the-horizon" allocation of 1 GB/day. Would sharing only 1 file but serving as an Ultrapeer be perceived as leeching?

--both machines are set with Force IP checked. I can't tell if this potentially confuses incoming requests, or if the Linksys router is handling them correctly.

-- uploads throttled ~75% (100KB/s) on both means that Ethernet speeds are also limited to 100KB/s, instead of >700KB/s seen before. Can the upload throttle be bypassed just for ethernet transfers?

--I can browse the G3 from the G4, but not vice-versa

--ethernet downloads from either machine are split into two streams. One downloads from the NAT address (192.168.*.3 or .2), the other stream from the router (192.168.*.0). I cna't understand the reason, and I hope such transfers remain within the LAN and do not register on the ISP's routers.
