Alcatel ADSL modem, Linux and Bezeq ADSL



We connected a LAN to the Internet via Alcatel's Speed Touch HOME ADSL
modem.  This modem is an Ethernet modem, and works with a regular phone
line (i.e. not ISDN).
The gateway is Linux-based, and we use Mulix' patched pptp (with the
--quirks option).

We use a Linux-based gateway/firewall (with kernel 2.2 and ipchains).

The connection works - we can fetch and send E-mail, telnet, FTP and surf
to several Web sites.

However:
1. This works with and without the --quirks=BEZEQ_ISRAEL option.
2. We can't surf to some Web sites both in Israel and abroad.

   Working in Israel:
     www.zak.co.il works, and so do news.walla.co.il, www.pointer.co.il.
   Working abroad:
     www.slashdot.com works, and so does newsforge.com.

   Do not work in Israel:
     quotes.globes.co.il does not work.
   Do not work abroad:
     linuxtoday.com, dailynews.yahoo.com.
3. The problem was experienced equally by MS-Windows NT, 2000 and Linux
   machines in the LAN.

According to tcpdump logs and firewall's logs, Web communication ceases
after 5 packets between the Web browser and the Web site, with no
indication of packets rejected by the firewall (and the firewall logs most
rejected packets).

I compared the tcpdump log of a successful Web surfing and a failed Web
surfing, and saw nothing relevant.

The MTU is set correctly (1500 in Ethernet interfaces, 1452 in pptp/ppp0).
The HOWTO-ADSL-BEZEQ (Ver 2.2 Sep 2001) was RTFMed.

>From Bezeq's side, the ADSL is correctly set up - a MS-Windows 2000 test
machine connected to the ADSL modem (with our gateway + network
disconnected) had no problems surfing the Internet.

Does anyone have experience with configuration similar to ours, or has a
clue where we should check further?

Will we need to have another --quirks option, for BEZEQ_ISRAEL_ALCATEL?

There is no IGLU Cabal.
There is a huge Israeli conspiracy to drown the Cabal members with trivia
having to do with quirks of connecting to broadband Internet in Israel.
