Questions about PPPoE

Hello,

I have configured my PPPoE connection using pppoe-setup, with a standalone firewall choice, nothing fancy. I have a couple questions:

1. In /var/log/syslog, there are lines for what seems to be packets. Lots of them. The destination is always the same, but the source is different every couple of lines. They look like this:

Code:

IN=ppp0 OUT= MAC= SRC=a.b.c.d DST=e.f.g.h LEN=40 TOS=0x00 PREC=0x00 TTL=251 ID=54321 PROTO=TCP SPT=51333 DPT=21320 WINDOW=65535 RES=0x00 SYN URGP=0

I've googled around, but I've found nothing. What do they mean?
2. At times, pppoe-start does its thing successfully, but pinging an ip or a site times out. And the terminal hangs after each command. After a while it returns to a normal state.
Anybody ever experienced this? Or have any ideas about it?

Thanks.
Ethan

1. I've googled around and found this. http://dnsbl.inps.de/query.cgi?lang=...=check&quick=0
If the packets are in your log, then your firewall is doing it's job. If they annoy you, write a rule to drop them completely without being logged.

2. Sometimes you are at the mercy of your service provider when it comes to quality of service.

1. I see, so it's just the firewall. Good to know.
2. So there's nothing I can optimise. Oh well.

Thanks for your opinion, allend.
