This machine is acting as a gateway, and throughput between the networks seems fine, but destinations local to the server have issues. >How-To-Repeat: I first noticed the issue with Mediatomb, a upnp media server from the ports collection. The server would appear as a destination on my client devices, but it appeared as though no data was returning from the server - I could not browse the contents. As part of troubleshooting, I ran the daemon in debug mode, and it looked like it was outputting the data correctly. I noticed then that there was data being built up in the Send-Q in netstat output. mcj@ark ~ % netstat Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 1551 ark.49152 192.168.1.50.61681 FIN_WAIT_1 I attempted to try the same thing with a different media server, ushare (also from the ports collection), and I got the same results, suggesting that the problem is not specific to Mediatomb. This machine also runs apache, which serves up some logfiles and mrtg-type graphs. When pulling up pages there, the HTML portion loads file, but the images referenced do not. Again, the data is getting stuck in the Send-Q. This suggests that the issue is not specific to the upnp protocol. mcj@ark ~ % netstat Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 25234 ark.http chibi.61526 FIN_WAIT_1 I have seen some discussion of this issue on the mailing lists, and it seems that Pyun YongHyeon is looking into the problem, but he does not currently have the hardware. I checked in the pr database, and did not see this issue reported, so I thought I'd go ahead and send it in myself. >Fix: None known. I have tried forcing the adapter to 100mbit, half-duplex, etc, but no setting seems to make a difference. >Release-Note: >Audit-Trail: >Unformatted:
