Dear All,
I just received the below mail from my ISP

-----------------
  On May 5th 2010 domain name system (DNS) will switch over to a new, more
secure protocol “DNSSEC”. DNSSEC adds digital signatures to normal DNS
queries, substantially reducing the risk of attacks such as the Kaminsky
exploit, which caused widespread panic in July 2008.

Here at FASTtelco we have taken all the necessary precautions on our DNS
and security equipments. Therefore if you own any security equipments such
as a PIX or an ASA please do the following changes at your end.  Below is
the configuration that needs to be changed on a Cisco PIX and a Cisco ASA
series firewall;

ASA:

policy-map type inspect dns preset_dns_map

parameters

message-length maximum 4096

policy-map global_policy

class inspection_default

inspect dns preset_dns_map

PIX:

fixup protocol dns maximum-length 4096

------------------

On further query wth the ISP it was told that if the firewall does not
have the neccessary changes we will not be able to browse.

Now I have our own Primary & Secondary DNS server running and I use
shorewall-4.0.14-1 as our firewall and its been working fine for the past
3 years or so .

the name servers are

1) ns1.kmun.gov.kw
2) ns2.kmun.gov.kw.

Now I would really apprecte if someone could advise me and help me on the
above issue. do I need to do any change in our firewall or no

we do hosts our company websites , mail servers , etc and the DNS servers
are authorative for these zones

wait for your kind help
if any more information is required pls do let me know

regards

simon
