What is your MTU? If your router is connected to ADSL, that may be it.
Set it to a smaller 1492.
PPPoE adds 8 bytes of extra overhead to the ethernet frames and the
correct initial maximum setting for the ppp0 interface MTU is 1492. If
the MTU is set too high, it may cause a fubar packet fragmentation
scenario, known as the Path MTU Discovery blackhole where the two ends
of the connection fail to communicate. A typical symptom would be the
failure of some web pages to load properly, and possibly other annoying
problems. You may need to also set the MTU for interfaces on any
masqueraded LAN connections MTU to 1452. This does not apply to PPPoA,
bridged, or routed configurations, just PPPoE! See rfc2923 for a
