512 is really low - analog modem style low, and not even "modern" v.90 modems, but old v.42 modems (which used 768 bytes IIRC). This accounts for the very slow speed, but it also indicates a very serious problem. But 512 is too a nice a number to be attributed to line noise, I think. I would suspect something wacky going on with hardware somewhere - either your DSL modem or the Bezeq DSLAM. > 2 - Although I can work, none of the other machines on my network (Linux or > Windows) can do anything on the Internet. You need to make sure that none of the other machines use MTU larger then 512. Its easy to do automatically by adding a "clamp MSS" entry to your iptables masquerading setup: STFW for "clamp-mss-to-pmtu". -- Oded ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
