Packet size issues - PPPoE connections are infamous for silently discarding oversized packets with no notification and, thus, breaking PMTU discovery. This discusses the problem and solutions under Linux: <http://linux-universe.com/HOWTO/IP-Masquerade-HOWTO/mtu-issues.html#AEN2563> This is usually visible as small packets working, but large packets failing. So, you see connection and can ping things, but your web request gets a tiny way and then stalls on large packets. :/ Daniel -- Copyright law is totally out of date. It is a Gutenburg artifact.
