G'day all, Somewhere between 4.3-RELEASE and 4.4-RELEASE something has changed which makes my PPPoE connection to Telstra ADSL (Australia) not work anymore. Has anyone else had this problem? More details follow: I have been using a regularly updated 4-STABLE machine running PPPoE with Telstra ADSL as my internet gateway since the beginning of the year. Before that I had used FreeBSD as a gateway for my dial-up account for a year and a half so I have some experience with this. Around late August after a cvsup, make buildworld, make installworld etc. I had trouble where certain types of traffic would start and then hang, mainly web traffic and certain things through ssh such as listing long directories. (Reminiscent of the MTU problems in the early 4 series but I don't think this is the issue as shown below.) I stuffed around but couldn't solve the issue so I backdated to 4.3-RELEASE and forgot about it for a while. Recently I decided to consolidate my machines and change my gateway so was brought back to this problem once more. I have now discovered that it seems to be the PPPoE connection itself which causes the trouble. I have done "identical" fresh installs of 4.3-RELEASE and 4.4-RELEASE on the same box. On each I have copied the attached ppp.conf then: kldload netgraph ppp -ddial -quiet -nat bigpond I also compiled all the netgraph stuff into the kernel to see if the behaviour differed from loading the modules. It didn't. Using 4.3 everything is fine. I run lynx and can happily browse the web directly from the box. I set up forwarding and then my linux, beos, freebsd, win2k boxes can all do whatever through it. Using 4.4 however, a http request starts but then sits "waiting for response" when using lynx straight from the box. Similar behaviour occurs for other hosts using it as a gateway. ssh will connect OK from and through the gateway, but certain actions hang the connection, e.g. ls -l of a big directory. I'm at my wit's end having searched newsgroups, mailing lists, and done the best crawl through the cvs changes that I can with my limited C skills. My best guess was that something changed sometime in or around August based on my notes from the time and the file dates on the gateway when I reinstalled 4.3-release to get things going again. Has anyone (particularly Aussies using Telstra ADSL) noticed this problem? Even better, can someone solve it for me?
