I don't know about ADSL specifics but there are some routine tests
which probably need to carried out:
1. If there is a firewall, have you fully adopted it to the new
situation?
2. What is the output of route?
3. Are there messages in the log about the IP of the ISP machine that
is next to you?
4. Have you tried to traceroute to some of the ISP machines? As far as
I remember from my israsrv experience, the sysadmin, not the support
desk, might need to set up some things which he forgot. Actually,
the best advise might be to talk with the sysadmin. I believe this
is Ronen who is also the son of the owner.

Most probably a DNS problem.

I would try with numerical IPs. I would also try numerical IPs for
servers inside the israsrv network, like 192.115.3.200 ==
www.israsrv.net.il.

The gateway in the routing table comes to mind as to something that
should been changed. I don't know if your scripts are clever enough to
do that by themselves.
