G'day everyone, Sorry I was out of the loop for a couple of days. One of our students handed in his thesis. It has been a tad busy. I did the following tests on my laptop by just remaking ppp alone (rather than the world like in my first attempts to track down the problem) using source from 12am 30th july and 12am 1st August. This was with a 4.4-stable kernel and userland. A few people with Telstra ADSL emailed me saying they have no problems at all using recent versions, (4.4 release and very recent 4.4-stable). However, it appears they have all used values of 1492 rather than 1454 for mtu/mru. Phillip Crumpler stated that he found these values by removing the set lines from his ppp.conf and letting it autonegotiate. I tried that and it indeed auto-negotiated values of 1492 and worked AOK. Directly setting the values to 1492 with: set mru 1492 set mtu 1492 worked OK too. However setting to 1454 didn't work in two aspects. First, rather than setting to 1454, the mtu was set to 1492 which agrees with the behaviour in the PR of Jim Housley: http://www.freebsd.org/cgi/query-pr.cgi?pr=32040 where the "set" option was observed not to "set" at all. Secondly, traffic with "large" packets failed to flow. On Brian's suggestion I tried set mru max 1454 set mtu max 1454 with the Aug 1st version which happily set the mtu and mru to 1454 and worked without a problem. Once I knew I could reproduce everything, I updated my gateway box to 4.4-stable, made the world and confirmed that the behaviour was the same on it as in my laptop tests with ppp from Aug 1st. So the strange behaviour was introduced on July 30th. I have emailed the ppp connection logs direct to Brian rather than send an (even more!) lengthy email to the lists. So the upshot is I now have a working 4-STABLE gateway (hooray!!) and can confirm the PR of Jim Housley. If anyone is using more recent versions of stable (post Jul 30th) with Telstra ADSL I am pretty sure they will have trouble if they follow Paul Hoadley's instructions (www.logicsquad.net) exactly. The "set mt[ur] 1454" has to be changed to either "set mt[ur] max 1454" or "set mt[ur] 1492". A big thanks to everyone who responded!! I really appreciate it.
